What is a noise dosimeter used for?

A noise dosimeter is specifically designed to monitor exposure to variable noise levels in occupational settings. It measures sound intensity over time, allowing it to record both constant and fluctuating noise levels in a work environment. This is essential for ensuring worker safety, as prolonged exposure to high noise levels can lead to hearing loss or other health issues.

By recording exposure data, the dosimeter helps in compliance with regulatory limits and in making informed decisions about noise control measures. The technology used in dosimeters typically includes a microphone to capture sound levels and processing units to analyze the data in real-time, which supports health and safety efforts in various industries.

The other options represent different types of measurements and monitoring techniques not related to noise exposure. For example, measuring ambient temperature is crucial for environmental control, calibrating sound systems is related to audio fidelity rather than personal exposure, and measuring air quality involves assessing contaminants in the environment, none of which align with the primary function of a noise dosimeter.
