Noise (dBA)
CAS Number:
N/A
Occupational noise is one of the most prevalent workplace hazards, affecting millions of workers across manufacturing, construction, mining, agriculture, transportation, and entertainment industries. Prolonged exposure to high sound levels causes noise-induced hearing loss (NIHL), a permanent and irreversible condition. Noise can also contribute to elevated stress, communication difficulties, and increased risk of accidents. Industrial hygienists measure noise exposure using sound level meters and personal noise dosimeters, expressed in decibels A-weighted (dBA). OSHA's Hearing Conservation Standard (29 CFR 1910.95) requires employers to implement hearing conservation programs when noise exposures meet or exceed the action level.
Noise exposure monitoring helps measure worker sound levels for hearing conservation and compliance. Use it in manufacturing, construction, mining, and heavy equipment operations where exposure varies by task and shift.
