## 2 Materials and Methods
The three most common techniques for evaluating the effects of vibrations on individuals in structures are as follows:  
* Root mean square method (RMS);
* Vibration dose method (VDV);
* Maximum instantaneous vibration value (MTVV). The Root Mean Square (RMS) approach, a widely favored method for gauging the impact of vibrations on individuals in built structures [3], follows a specific procedure outlined in Equation (1). Each signal amplitude is squared to eliminate negative values, and then averaged to get a representative value which is finally square rooted. \[\text{RMS}=\sqrt{\frac{1}{N}\sum_{i=1}^{N}x_{i}^{2}} \tag{1}\]  
where  
\(x_{i}\) represents signal measured values;  
\(N\) is the number of samples. To conduct a comprehensive analysis, RMS values are computed across frequencies spanning 1 Hz up to 80 Hz, against the set thresholds in the established normative guidelines [25]. Valued for its application in industrial standards such as [13; 23], this method offers a dependable evaluation of prevailing vibrational conditions. It particularly excels in assessing human comfort in the face of gradual or consistent vibration variations. However, its limitation lies in its inability to effectively capture short-lived or high-intensity vibrations. This technique's efficiency shines in providing an accurate depiction of ongoing vibration levels within structures. Simultaneously, it gives a precise measure of comfort levels in the presence of slight or steady oscillations. Nonetheless, it remains challenged by its underperformance when it comes to identifying abrupt or intense vibration occurrences, which demand more specialized detection methods. The second method, VDV, represents an innovative approach that assesses the cumulative impact of vibration exposure over an extended period. This technique not only provides a more complex analysis but also simplifies a comprehensive evaluation of the persistent effects generated by prolonged vibration exposure. The VDV calculation, which involves raising the acceleration to the fourth power, places a significant emphasis on larger vibrations due to their heightened impact. This mathematical formulation, as depicted by Equation (2), emphasize the importance of accurately quantifying the effects of varying vibration levels on human responses. \[\text{VDV}=\left[\int_{0}^{T}a_{w}^{4}(t)dt\right]^{\frac{1}{2}} \tag{2}\]  
where  
\(a_{w}(t)\) is the weighted value of vibration acceleration as a function of time;  
\(T\) is the measurement time. In the field of vibration evaluation, the VDV method stands out as a valuable tool for predicting potential adverse reactions in individuals exposed to vibrations. The standardized procedures outlined in the international standard [23; 24] and national standards [13; 25] provide a structured framework for implementing the VDV approach effectively. However, one notable limitation of this method is its inherent complexity, necessitating more advanced data processing techniques and a larger dataset to derive meaningful insights and ensure accurate assessments of vibration-related risks and potential health implications [9]. Despite its analytical complexity, the VDV method remains a necessary component in the assessment of vibration exposure and its impacts on human well-being, offering a robust framework for understanding and managing vibration-induced health risks in various occupational settings. The final approach considers MTVV, which highlights the peak value of transient vibrations (see Equations (3a) and (3b)); it provides a measurement of the highest vibration intensity. The MTVV method enhances the RMS and VDV methods by offering additional details regarding the peak vibration level, thereby providing a comprehensive analysis of vibration characteristics [9]. This technique is typically applied to vibrations resulting from construction activities or heavy vehicle movement, serving as a valuable tool for assessing the impact of these activities on surrounding structures and environments.
