Indoor Noise Level Check

Why do we need Indoor Noise Level Check?

Measuring noise levels and workers’ noise exposures is the most important part of a workplace hearing conservation and noise control program. It helps identify work locations where there are noise problems, employees who may be affected, and where additional noise measurements need to be made.

How it is done?

For Indoor Sound level checking, sound level meters are used as measuring instrument to assess noise or sound levels by measuring sound pressure. They are often referred to as a sound pressure level (SPL) meters, decibel (dB) meter, noise meter or noise dosimeter. A Sound level meter uses a microphone to capture sound which is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.
