Workplace Noise Exposure and Relative Health Hazardous Among the Power Loom Workers – A Cross-Sectional Study
Authors: Sen Somnath , Ravichandran Beerappa , Karunamoorthy Panjakumar 
Published: February 2025

Background
Exposure to excessive noise in the workplace is a potential risk, and higher noise levels with longer exposure can lead to increased noise-induced hearing loss (NIHL). Furthermore, noise exposure is the second most common risk factor in the workplace, after workplace injuries in an occupational exposure setting.

Objectives
The objective of this study was to find out the prevalence of NIHL among the workers in the power loom industry.

Material and Methods
This cross-sectional study was carried out at a home-based small-scale weaving factory (power looms) located in Bangalore city to find out the occupational noise exposure and NIHL during the year 2019–2020. Noise exposure monitoring was carried out in 12 power loom workplace areas using a portable integrated sound level meter along with frequency spectra bands. A total of 172 (122 male and 50 women) workers took part in the study. An audiometric test was carried out among the workers along with personal details and lifestyle factors with a predesigned questionnaire.

Results
Noise monitoring was conducted at power looms to evaluate the exposure assessment. It was found that the study population was highly exposed to noise with a full shift noise exposure of 95.7dB(A). The mean ranges of Leq and TWA in this study were 92.3–100.2 dB(A) and 84.4–95.9 dB(A), respectively. The octave band analysis of noise of high sound levels with the frequencies of 1000 Hz, 2000 Hz, and 4000 Hz was carried out, and the highest sound intensity was recorded in 2000 Hz frequency followed by 4000 Hz above 90dB(A) in both frequencies. The audiometry test was conducted on 69 workers (60 men and 9 women) who voluntarily participated in the pure-tone audiometry. Out of 69 workers, 60 (87%) of the study group suffered from noise-induced hearing loss.

Conclusion
The study was conducted in an unorganized sector where high noise in the power looms may be the use of machines without any shielding with soundproof materials/barriers from the workplace. The inadequate acoustic design and poor machinery maintenance may also be a reason. This study elucidates the trends in the burden and risk of hearing loss among workers in hazardous noise environments.

Представлена институциональная структура региональной продовольственной системы как многокомпонентная совокупность формальных и неформальных институтов. Выделены функции институтов в региональной продовольственной системе. Рассмотрены особенности функционирования продовольственной системы Удмуртии с учётом типа экономического поведения местных органов власти, традиций и обычаев сельских жителей. В качестве институционального барьера функционирования продовольственной системы Удмуртии показано отсутствие паритетности в налоговых отношениях федерального центра и региона. Сделан вывод о необходимости совершенствования внешней и внутренней институциональной среды региональной продовольственной системы.
Introduction. The coherence and balance in the functioning of all the subsystems of the food system are the obligatory conditions for the stable functioning of it in a region. Thus, the institutional provision for the food system is needful. The goal of the research is to ground the institutional conditions for the stable functioning of the regional food system. A multi-component structure of formal and informal institutions is rather typical for a food system. At that, the institutions shall belong to the field of production, distribution and consumption of food. If economic agents are ineffective in coming to an agreement with each other, a need in the external enforcement arises. The state includes such functions as assessment of current situation and definition of the measures for an adequate support of the most significant economic institutions, and performance of institutional transformations with a view to establish the conditions for the development of the entire food system. No clarity when providing state support for the regions leads to the lobbying of separate communities. This causes both concentration of food production in the developed regions and creation of work places, household income as well as a high level for food consumption. Disparity between the regions in the income level and food consumption is an institutional trap for the food system and the entire economy of the region. Results. The particularities of the food system functioning in Udmurtia with due account for the type of economic behavior of the local authorities and traditions and habits of villagers were considered. As an institutional barrier for the Udmurtia food system functioning, lack of parity in the fiscal relations of the federal authorities and the region is demonstrated. Conclusion. Institutional conditions for the functioning of the regional food system shall be improved and transformed in accordance with the changes of internal and external social and economic factors for food security of the region and all the country. In order to reduce the disparity of the regions on the level of food consumption and to alleviate the dependence of food consumption on the population income level, it is obligatory to establish appropriate institutions.

Introduction. Management decisions are a central element for complex tasks in social, economic, environmental, and political systems. The main feature of such systems is the weak structuring of knowledge about a system, strong mutual influence between the parameters of the system is the central feature of such systems. That is, there are practically no independent control parameters in the system, which significantly complicates its study. In decision-making theory, such problems are called “weakly structured” or “non-structured”. Furthermore, the main characteristics are qualitative. For this reason, sufficiently reliable quantitative models for their description and solution are missing. The goal of the research is to give a rational reasoning for application of the methods for solving complex management problems. Methods. An attempt to apply the methods of the classical theory of decision-making under the conditions of complex problems led to the development of a new direction in the theory of decision-making - “unique choice”. Methods and technologies of unique choice are developed as a result of adaptation of classical decision-making methods to the conditions of lack of information at the time of decision-making and as a result of uncertainty in the estimates of alternatives, as well as the lack of objective quantitative scales for evaluating alternatives. This inevitably leads to the growing importance and value of expert assessments in the tasks of the unique choice. At the same time, low efficiency of applying the unique selection methods for solving complex problems, even with high expert competence, is primarily due to the weak structuring of these tasks. Use of simulation modeling (system dynamics) as a tool of the system approach can significantly improve the efficiency of managerial decision-making in the conditions of weakly structured tasks. Conclusion. Simulated models built on the basis of expert knowledge are of high operational value. They enable the investigation of the dynamics of mutual influence of the parameters of a complex system, which makes it possible to identify the cause and effect relationship both “inside” the complex system and with the “host” system (archetype). Understanding of the processes of the system under study as a subsystem of the containing system significantly increases the efficiency of the decisions made to manage this system
