The main goal of a hearing conservation program is to prevent hearing loss among workers exposed to high levels of occupational noise.
Engineering controls, such as installing noise barriers or soundproofing materials, aim to reduce noise at the source or along its path to the worker.
OSHA's permissible exposure limit (PEL) for noise is 90 decibels (dB) over an 8-hour workday.
Using both earplugs and earmuffs together offers the highest level of noise reduction and is recommended in extremely loud environments.
Noise monitoring helps to evaluate the levels of noise in the workplace and ensure that they are within safe limits as defined by regulations.
