Hearing protection standards

Hearing protection is the last line of defense against hazardous noise. But before those are used, the Occupational Safety and Health Administration (OSHA) has additional regulations in place to help mitigate injury when hazardous occupational noise exposure is present. OSHA 29 CFR 1910.95 requires employers to use engineering and administrative controls to reduce excessive noise levels. Even a reduction of a few decibels can reduce risk and noise-related annoyance, as well as improve communication. If these controls fail to reduce noise to permissible levels, a Hearing Protection Device (HPD) must be provided and used. Hearing protectors must be tested and approved by the American National Standards (ANSI) in accordance with OSHA and must be labeled with a Noise Reduction Rating (NRR) label per requirements put forth by the US Environmental Protection Agency (EPA). Additionally, when noise exposure levels equal or exceed an 8-hour time-weighted average sound level (TWA) of 85 dBA, OSHA requires a hearing conservation program to be implemented. The goal of these programs is to strive to prevent initial occupational hearing loss, preserve and protect remaining hearing, and equip workers with the knowledge and hearing protection devices necessary to safeguard themselves.

Note that in some very loud environments, workers should wear double hearing protection (earplugs and earmuffs).

Please refer to the OSHA standard for complete details.
