Dosimetry is a common method for evaluating noise exposure levels in the workplace, as it involves the use of noise dosimeters that measure the cumulative noise exposure of an individual over a specified period. These devices are typically worn by workers during their shifts and provide data that reflects the actual noise levels they encounter, which is essential for assessing compliance with occupational safety standards and determining the need for hearing conservation programs.

In contrast, noise mapping involves creating a visual representation of noise levels across different areas, which, while valuable for understanding general noise patterns, does not provide specific information about individual worker exposure. Sound level measurement can assess instantaneous noise levels at specific points in time, but it does not account for the duration of exposure across an entire work shift, which is crucial for a complete evaluation. Employee surveys can gather subjective experiences related to noise but lack the quantitative data necessary for a comprehensive assessment of actual noise exposure levels experienced in the workplace.
