A low-order simulation model for wind turbine infrasound prediction
Authors: He Dazhuang , Liu Yangfan
Published: June 2023

Wind energy is one of the fastest-growing renewable energy technologies. One of the environmental concerns associated with wind energy development is noise emission from wind energy facilities, especially the low-frequency noise and infrasound that allegedly raises public health concerns.
In order to analyze the noise emission from wind turbines and to aid future wind energy development, a numerical simulation tool for the prediction of low-frequency noise and infrasound emission from wind turbines is developed. The simulation tool is a low-order model developed by combining
aerodynamic noise theories and basic working principles of wind turbines. 2-D airfoil aerodynamics calculation is coupled with a subroutine that solves Ffowcs Williams-Hawkings (FW-H) equation in time domain. By omitting unsteady aeroacoustics mechanisms, the low-order simulation model is
capable of computing infrasound emissions from multiple wind turbines simultaneously. By utilizing the low-order simulation model, the effects of wind directions, wind turbine locations, and phases of wind turbine rotations on the consequent aerodynamic infrasound are studied. Results of aerodynamic
infrasound computation imply that wind farm configuration or wind turbine phase adjustment can help reduce the noise level at certain locations, which makes the low-order simulation model a useful tool to aid wind farm siting and controlling.

Published: June 2023

Corsi-Rosenthal (CR) boxes efficiently and cost-effectively clean the air in an environment; however, the constant broadband noise they produce is a concern. Measuring sound power levels of CR boxes would provide a metric for noise comparisons, but traditional sound power level measurements
are not readily adaptable for the average consumer. Measuring the sound power level in a free field over a reflecting plane is an accurate method but is complicated and expensive involving multiple microphones in an anechoic chamber (ANSI S12.54-1999). The Comparison Method is a simpler procedure
that can be performed directly in the environment of interest but requires an expensive calibrated source (ANSI S12.57-2011). To allow for simple and inexpensive sound power measurements of CR boxes, we used ANSI S12.54-1999 to measure the sound power of a $30 hand vacuum (Black+Decker
HNVC115JB06) to explore its potential as a DIY calibrated source for the Comparison Method. The reproducibility and uncertainty of this DIY method will be discussed. The DIY method has the potential to enable noise comparison of air cleaners or other devices for the average consumer.

Published: June 2023

Agricultural tractors are special purpose machines that perform agricultural operation in harsh environments such as unpaved roads and farmlands, and generate high levels of noise and vibration. Eco-friendly tractors using electric drivetrains and hydrogen fuel cells are being developed
to reduce exhaust gas in accordance with global environmental regulations. Unlike traditional tractor structures, these electrified tractors are being developed as modular and shared platforms. Therefore, it is changing into a system that is easy to apply component-based transfer path analysis
(C-TPA) to reduce noise and vibration of tractors. In this paper, the noise and vibration contributions of an agricultural tractor were analyzed using C-TPA, and the blocked force usable as the excitation force of the virtual model was derived. The accuracy of transfer path analysis was improved
by applying transfer functions including the rotational directions using virtual point transformation technique. The prediction result of developed experimental model were similar to the vibration response of the actual tractor, and the contribution of structure-borne noise could be quantitatively
evaluated.

Noise engineering is not a new field of study but statistics showed that experts in the field are on a decline. Observing that motivation and curiosity are among the hallmarks of any workforce development pipeline, the study developed an experiment-centric pedagogy to detect and measure
noise from pollution using low-cost hands-on devices with the aim of motivating learners. The study design was a pre- and post-test method. The learners were enrolled in a transportation course and the noise detection and measurement strategies course module was used for the study. Motivated
Strategies Learning Questionnaire was adopted for the study. Learners response to the use of technological tools incorporated in learning was predominantly positive revealing that the learners' gain extensively. More so, significant improvement was observed in the critical thinking of leaners
(p < 0 .05) and overall, there was an increase in their motivation at the post-test. Significant improvement in academic performance of learners was also observed at post-test (p < 0 .05). It is therefore posited that there is need for effective engagement with learners with similar
low-cost hands-on to lead to better understand and motivation that can lead to development of workforce in noise engineering.
Laboratory measurements of lightweight floating floor systems on cross-laminated timber (CLT) slabs
Authors: Hunt Bradlay , Wells Adam , Rodrigues Marina
Published: June 2023

Mass timber family of products (including cross-laminated timber - CLT) offer an alternative to fossil fuel-intensive materials for many applications and an opportunity to reduce the carbon footprint of the built environment. However, the use of mass timber in multi-family and commercial
buildings presents unique acoustic challenges. Additionally, one of the most desired aspects of mass timber construction is the ability to leave a building's structure exposed as finish, which creates the need for asymmetric assemblies. This means that when speaking about floor/ceiling applications,
preferentially any acoustical component should be installed on top of the assembly. To measure airborne sound reduction and impact noise isolation of lightweight floating floor systems and confirm CLT assemblies can provide satisfactory sound insulation, CDM Stravitec launched a testing campaign
(done on Belgian Building Research Institute, institution recognized by application of the decree-law of the 30th of January 1947), where measurements were made considering several types of decouplers, such as: discrete bearings with multiple thickness and/or different void depth (filled in
totally or partially with insulation material) and mats and strips placed between the CLT slab and different timber, cement and gypsum-based boards with and without use of the well-known constrained layer damping technique. This paper will present the findings of the test campaign.
Development, Construction and Certification of a Facility for Exterior Noise Regulatory Compliance Testing
Authors: Sorenson Steve , Rasmussen Robert , Rollison Jim
Published: June 2023

OEMs are required to meet applicable regulations for exterior noise. Acceleration noise (typically called pass-by noise) regulations have an upper limit for noise emission. In addition, vehicles which can operate without a combustion engine must comply with regulations for minimum noise
emitted during low speed driving. In order to make regulation-compliant measurements for global destinations, a test track meeting requirements of ISO 10844 may be necessary. However, strictly meeting this requirement doesn't guarantee a usable facility for efficient measurements. This paper
describes design goals, challenges and construction of a regulation compliant facility in Arizona. The intent was to build a facility with a long usable life before requiring repaving, sufficient isolation from nearby test roads, 24-hour usability and onsite amenities to accommodate technical
staffs and vehicle retrofits. Consideration of needs of all stakeholders was necessary to make a facility not only regulation-compliant but also attractive to internal and external customers.

Published: June 2023

Fast NVH analysis from the start of the motor design is important to speed up product development by avoiding major NVH issues later. In this paper, different methods for electric motor noise and vibration predictions are proposed for different stages in the design process. The results
are compared to previous experimental validation [1]. The first method combines electromagnetic finite element analysis to calculate the forces, with analytical models for the stator vibration and acoustic response [2]. This requires minimal structural design data, and can be carried out rapidly,
allowing the exploration of many design possibilities in the early design stage, and is implemented in Ansys Motor-CAD. This is compared with the full structural finite element analysis (FEA) [1]. It is shown that the fast analytical NVH process provides a good prediction for the motor noise
level early in the design process. The structural FEA approach provides additional information about the structural response at a later stage to refine the design. The use of frequency response functions (FRF) derived from the structural FEA are demonstrated, allowing the rapid calculation
of noise results from the electromagnetic forces.

Published: June 2023

Ensuring the robustness of vehicle systems and features is a key aspect of customer satisfaction and therefore is of vital importance to Original Equipment Manufacturers (OEMs). Both initial quality and quality over the life of the vehicle are important aspects to customers. Therefore,
some features and systems require an active approach at monitoring system health. The intent of Active Noise Cancellation (ANC) systems in vehicles is to increase the customer's perception of vehicle refinement and brand quality. Due to the nature of ANC system operation, it is critical that
the system does not go divergent resulting in unwanted noise being heard by the customer. So, a method to monitor the ANC system operation and performance is required to ensure robustness. Despite tuning ANC systems considering expected vehicle build tolerances, vehicle aging and customer
specific use cases, an ANC system can occasionally still go divergent in the field. An ANC audit procedure is included in the system software to verify functionality and performance at End of Line (EOL), repair centers or verified though an Over the Air (OTA) procedure. This type of procedure
can verify the vehicle's acoustic cavity response and update ANC tuning parameters to account for any changes. This paper will show vehicle examples of why an ANC health monitoring system is needed and how we developed, implemented, and utilized an ANC audit procedure to improve ANC system
robustness and customer satisfaction.
Feedforward Harmonic Suppression for Noise Control of Piezoelectric Synthetic Jet Actuators
Authors: He Zixin , Mongeau Luc , Taduri Rahul , Menicovich David
Published: June 2023

Piezoelectrically driven Synthetic Jet Actuators (SJAs) are a class of pulsatile flow generation devices that promises to improve upon steady forced cooling methods in air flow generation, surface cleaning and heat transfer applications. Their acoustic emissions and vibrations, an intrinsic
by-product of their operation, needs to be mitigated for applications in noise-sensitive contexts. Already used for aerodynamic control [1, 2], thrust vectoring [3], spray control [4], and heat transfer [5, 6], they are increasingly being considered for sensor lens cleaning in automobiles.
In this study, the sound generation mechanisms of SJAs are discussed and an active noise reduction method is proposed and evaluated. Driven with a single frequency sinusoidal input, SJAs produce acoustic emissions at harmonic frequencies within the frequency range of speech communication.
The sound pressure levels of those emissions are commensurate with that of other automotive subsystems and electronic components. Previous attempts at noise control include passive strategies, such as, nozzle design [7, 8], enclosure design [5], and mufflers. Active strategies, such as out-of-phase
actuator pairs [9], and signal modulation have also been considered. Given their relative novelty, further reduction is possible at the source through the tuning of prominent tonal components of their emissions. The present study demonstrates that feedforward active control, achieved through
input harmonic tuning, results in significant drops in the loudness of the radiated sound with minimal effects on flow and cleaning performance. Acoustic emissions from all prominent harmonics could be reduced using this method. Tuning is local to the location of the error microphone and further
work is required to achieve global tuning. Preliminary performance investigations are presented.
Active Vibration Control of Motor Driven Power Steering for Reduction of Interior Noise
Authors: An Kanghyun , Baek Jiseon , Lee Sang-Kwon , Jang Daewon , Shin Soohyun
Published: June 2023

This study presents a novel active vibration control (AVC) system on motor driven power steering (MDPS) to reduce interior noise reduction caused by operating the MDPS in an electric vehicle. MDPS is electronic power steering (EPS). The MDPS attached to the rack gear of power steering
system is called R-MDPS. Operating of the R-MDPS generates a structural vibration of R-MDPS, and the vibration is transmitted to car body through mounts of car subframe. The vibrating body of car becomes a monopole and dipole sources of vibroacoustic noise generated inside car. This vibracoustic
noise is a structure borne noise and makes passenger annoyance. To reduce interior noise inside a car directly, active noise control (ANC) has been used as active method and is a useful method for active cancellation of the low frequency noises less than 400Hz. However, in this study, because
the frequency range of interior noise due to operation of R-MDPS is higher than 400Hz, the AVC system is employed and is applied to active cancellation of the vibration transmitted to car body through the subframe mounts. For application of AVC to test car, the control force is required and
the actuator for generation of control force should be install on the mounts. For application of AVC to test car, the control force is required and the actuator for generation of control force should be inserted in the mount between subframe and R-MDPS. It requires an extra rework of test
car. In this study to study the feasibility for the application of AVC system to R-MDPS, the test jig, which composes of R-MDPS and subframe of test car, is made and is set up in the laboratory. All study on AVC is performed in the laboratory. The proposed method is successfully applied to
the active cancellation of vibration at target point of subframe. The developed method is going to be applied to the AVC of real test vehicle.

Published: June 2023

The implementation of enablers on a luxury sport utility vehicle is used to illustrate the development process for reduction of road noise. The vehicle in this case study was launched into production with two tuned mass dampers for reduction of low frequency road noise content which
was amplified by frame modes. Additionally, resonators were integrated into the wheels (rims) to address the dominant cavity resonance frequencies. The results of this successful production implementation are illustrated herein. An RNC (road noise cancellation) system was integrated into the
case vehicle to assess its performance relative to the passive enablers listed above. This production representative (embedded software solution) RNC system utilized the vehicle's existing audio system for creation of active noise to cancel noise content which was predicted using accelerometers
mounted to the vehicle chassis. A comparison of in-vehicle noise indicated a significant reduction at low frequencies (at all seating locations) when utilizing the active noise control solution. These noise improvements are coupled with a vehicle mass reduction of greater than 4 kg, when compared
to the passive enabler solution.

Published: June 2023

HVAC systems are of critical importance in ensuring passengers' thermal comfort inside the car cabin as well as safety requirements for defogging functions. These systems involve various components and subcomponents such as blowers, thermal exchangers or actuators, with a wide range
of well-known technologies and also new ones on recently introduced innovative products. Currently, within established electrification trends worldwide, the HVAC system is becoming the most important embedded system that can induce major contribution of noise and vibration. These NVH issues
can emerge through different transfer paths inside the car cabin possibly causing significant discomfort to passengers. During developments, the NVH issues are mastered and contained by both suppliers according to internal requirements and OEMs according to specifications. However, OEM specifications
are mainly defined by overall noise levels and improvements over the years are generally consisting of reducing these specified levels. Furthermore, some HVAC NVH issues may not be well detected when using regular NVH metrics. This raises concerns about the limitations of the regularly used
metrics in ensuring specification compliance and, above all, in depicting a subjective assessment at component level. Throughout a statistical analysis of HVAC systems population, this paper first focuses on the discrepancies between the data provided by traditional NVH metrics and subjective
evaluations. Then, a deeper analysis involving psychoacoustic metrics provides a relevance overview of the applied metrics depending on the encountered issues and compared to a subjective assessment. Finally, from a responsibility perspective, these findings raise questions about the relevance
of regular metrics used by OEMs and the right way to handle HVAC NVH topics nowadays.

A multilayer acoustic treatment constructed of fibrous acoustic absorption material combined with dissipative acoustic material achieves a low profile and is lightweight and multi-functional, with properties that are desirable for NVH (noise, vibration, and harshness) treatments. The
dissipative material consists of microfibers and acoustically active particles; this material was introduced in the last SAE NVH conference: A Novel Dissipative Acoustic Material [1]. In this paper, the acoustic performance of the multilayer treatment was evaluated by using random incidence
absorption and transmission loss measurements, as well as in-vehicle experiments. Absorption and transmission loss were additionally modeled using the transmission matrix method (TMM). In the in-vehicle test, an OEM wheelhouse liner with Trim, for an SUV, was evaluated utilizing this new multilayer
3M treatment.
Noise footprint assessment at a vertiport for different approach and departure procedures of a tilt-wing air-taxi
Authors: Bauer Michael
Published: June 2023

Community noise at vertiports is one of the most important questions related to upcoming urban air mobility (UAM) operations. While fixed-wing and/or fixed-rotor aircraft can mainly be treated by their changing operational parameters, such as rotor or propeller rpm, tilt-wing or tilt-engine
configurations are more difficult to simulate because of their constantly changing noise emission and spatial radiation characteristics. The work presented in this paper is providing an overview of the noise situation at a virtual vertiport which is being approached and departed by a tilt-wing
air-taxi in different ways. Several different departure procedures are simulated with the same generic air-taxi. For the noise emission semi-empiric methods were used. During the air-taxi's descent and climb, different tilt configurations are included, mainly defined by the time dependent
engine's tilt-angle, but also related to different approach paths. Each approach or departure procedure is generating individually time dependent changing noise emission characteristics which are used for noise footprint mapping around the touch-down or lift-off point. Different noise metrics
are computed, including some which are representative to indicate noise annoyance among the vertiport's neighborhood. It is expected that each procedure will generate its own specific community noise situation in the vicinity of the vertiport, and thus may provide an early recommenddation
for later operations. The results are compared towards each other. Additionally, a simulated certification flyover according to ICAO Chapter 13 - which is about the noise certification of tilt-rotor aircraft - is set into relation to the vertiport's community noise.

Published: June 2023

Numerical methodologies for aeroacoustic analyses are increasingly crucial for car manufacturers to optimize the effectiveness of vehicle development. In the present work, a hybrid numerical tool based on the combination of a delayed detached-eddy simulation and a finite element model,
which relies on the Lighthill's acoustic analogy and the acoustic perturbation equations, is presented. The computational aeroacoustics is performed by the software OpenFOAM and Actran, concerning respectively the CFD and the FEM. The aeroacoustic behavior of the SUV Lamborghini Urus at a
cruising speed of 140 km/h has been investigated. The main aerodynamic noise phenomena occurring in the side mirror region in a frequency range up to 5 kHz are discussed. The numerical simulations have been verified against the measurements performed in the aeroacoustic wind tunnel of the
University of Stuttgart, operated by FKFS. The predicted exterior noise propagation into the far field has been validated by comparing the sound pressure level with the experimental data measured by exterior microphones, which were located outside the turbulent region beside the wake of the
side mirror. Furthermore, the noise transmission into the cabin through the side window has been modeled. Simulation results have been validated by means of interior microphones installed on the driver seat. Both the exterior and the interior noise predictions show very good correlations with
experiments. Lastly, a comprehensive investigation of the most critical aeroacoustic sources has been carried out. The numerical tool has been proven to be in good accordance with the microphone array with respect to the distribution of the sound pressure level in the proximity of the side
mirror. Besides, the main vortex structures involved in the generation mechanisms of wind noise have been investigated by a CFD analysis. The entire CAA process has been proven to be accurate and suitable for combined analysis between the generation mechanisms of wind noise and the resulting
transfer into the interior cabin to the driver's ear as well.
Improvements to a Method to Simulate Non-Stationary Wind Noise in Vehicles
Authors: Yu Jinghe , Davies Patricia
Published: June 2023

As the vehicle and wind speeds and directions change, the unsteady flow creates non-stationary wind noise. To investigate people's perceptions of non-stationary wind noise, a method to simulate the non-stationary wind noise is needed. Previously, a method was developed that used stationary
recordings taken at several speeds and directions to create a set of sound pressure level predictions in each one-third octave band that are a function of wind speed and direction. These functions are used to create time-varying filters based on provided wind profiles. A reference wind noise
measurement is then filtered to produce the sounds. A drawback of this method is that many stationary wind condition measurements are needed to form accurate sound pressure level functions, which can be time consuming. A method requiring fewer measurements was investigated. At each yaw angle
one non-stationary noise measurement and one stationary reference measurement are used to estimate the relationship between sound power and wind speed. The accuracy of the estimation was validated by comparing wind noise simulations with wind tunnel measurements, A further improvement is to
use partially correlated white noise signals to simulate binaural sounds that have a similar coherence structure between the left and right ear sounds to that observed in binaural measurements in the vehicle.
Aeroacoustic Vehicle Development Method Considering Realistic Wind Conditions
Authors: Staron Domenic , Riegel Matthias , Blumrich Reinhard , Wagner Andreas
Published: June 2023

The aeroacoustic development of vehicles is still mainly carried out in wind tunnels under steady flow conditions, although the real situation is different. However, as discussed in several earlier publications, a vehicle experiences unsteady, turbulent flow on road, which results for
example from natural wind, wakes of other vehicles, or obstacles at the roadside in combination with side wind. The resulting temporal variations of the wind noise inside the cabin affect the passengers' comfort and safety through fatigue. To be able to also consider the unsteady aeroacoustics
in the vehicle development process, a comprehensive method has been developed that is presented in full for the first time in this paper. The on-road situation is simulated in a realistic and reproducible manner in the full-scale wind tunnel of the University of Stuttgart by means of an active
turbulence generator, developed by FKFS. The turbulence generator allows to dynamically vary the flow angle with frequency components of up to 10 Hz. By comparing the unsteady wind noise for different flow situations and different vehicles, a flow scenario has been derived which leads to representative
and meaningful aeroacoustic results. The measured temporal wind noise variations are investigated using modulation analysis, which has been adapted to show only relevant information in a comprehensible way. Finally, a psychoacoustic metric for rating the annoyance of unsteady, as well as steady,
wind noise has been developed based on listening studies. The metric describes the subjective perception and allows evaluation and optimization of the aeroacoustic behavior specifically regarding the passengers' comfort. With this new method all wind noise aspects, steady as well as unsteady,
can be determined and taken into account for vehicle development. The evaluation and comparison of vehicles and variants is comprehensive and is focused on the passengers' comfort.

The purpose of this study is to examine the impact of CSR disclosure and EPS on firm value in mining companies listed on the ISSI, with size acting as a moderating variable. This is based on the fluctuating firm value, the increase in conflicts related to CSR, and the difference in firm value proxied by Tobin's Q and EPS. A purposive sampling technique was used to obtain the number of research samples, with 15 mining companies consistently registered at ISSI for the 2016-2020 period. This is a quantitative study that employs multiple regression analysis with panel data and moderated regression analysis with a statistical data processing application. According to the results, CSR disclosure has a negative and insignificant effect, whereas EPS has a positive and significant effect on firm value. Simultaneously, CSR and EPS disclosures have a significant effect, and the size variable is unable to moderate this effect.

The continuous combustion of non-renewable fossil fuels and the depletion of the natural resources from which they come and, consequently, the continuous increase of carbon dioxide (CO2) emissions into the atmosphere are intensifying the search for the conversion of carbon dioxide to fuels and value-added chemicals, with the main objective of reducing emissions and creating renewable and sustainable energy sources. In this sense, there is a lot of interest in the photocatalytic reduction of CO2 with H2O, mainly using solar energy, which is a renewable source with a continuous and easily available light supply. Recent progress in this area has focused on the development of promising photocatalysts, primarily based on TiO2. In this context, this article analyzes: (i) the role of CO2 in the treatment of problems related to energy and global warming, (ii) the fundamental knowledge of the photocatalytic reduction of CO2, (iii) the role of the catalysts of copper-doped TiO2 in the photocatalytic transformation CO2; as well as (iv) emerging and crucial opportunities for future research employing Cu-TiO2 photocatalysts; mentioning the most up-to-date relevant references.

A população transexual possui um histórico de dificuldades para acessar os serviços de saúde pública, seja qual for o motivo de procura de atendimento. Porém, no que se diz respeito ao acesso ao processo transexualizador, os desafios são ainda maiores. Mesmo com a implementação do Processo Transexualizador do SUS em 2008, as pessoas trans ainda enfrentam dificuldades, seja por preconceito ou por falhas das próprias diretrizes do processo. Dessa forma, o objetivo desse estudo é identificar os principais desafios encontrados por pessoas que precisam realizar o processo transexualizador no SUS. Trata-se de uma revisão integrativa, na qual, através de conhecimentos prévios de outros autores, formula-se informações sobre o objetivo proposto, o qual fará uso de critérios de inclusão, como estar disponível na integra em português, inglês ou espanhol e ter alguma perspectiva ou ponto de vista sobre o tema proposto, e exclusão, como monografias e teses de doutorado, para seleção desses estudos nas bases de dados BVS, LILACS e SciELO a partir das palavras-chave: “Transexualidade”, “Travestilidade”, “Acesso e Cobertura Universal de Saúde” e “Sistema Único de Saúde”. Espera-se, que os desafios enfrentados por uma pessoa que precisa realizar o processo transexualizador no SUS, sejam minimizados, e que mais profissionais sejam capacitados garantindo o direito de acesso ao sistema de saúde livre de discriminação, bem como, um atendimento acolhedor e respeitoso, sem deixar de lado o uso do nome social. Em síntese, acontece discriminação nos serviços, falta de qualificação dos profissionais, acolhimento inadequado, discriminação baseado em crenças, entre outras dificuldades. Logo, é fundamental que aconteça a mudança nesse cenário, e assim, aconteça um atendimento no sistema de saúde livre de discriminação e outros tabus existentes.
