Noise Monitoring: 29 CFR 1910.95(d) requires that monitoring be conducted when "any employee's exposure may equal or exceed an 8-hour time-weighted average of 85 decibels. Audiometric Testing: 29 CFR 1910.95(g) requires an "audiometric testing program" for "all employees whose exposures equal or exceed an 8-hour time-weighted average of 85 ...
Personal noise dosimeters. A noise dosimeter (American English) or noise dosemeter (British English) is a specialized sound level meter intended specifically to measure the noise exposure of a person integrated over a period of time; usually to comply with Health and Safety regulations such as the Occupational Safety and Health (OSHA) 29 CFR 1910.95 Occupational Noise Exposure Standard [1] or ...
Occupational noise. Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage. Occupational noise is considered an ...

Mine Safety and Health Administration (1999; 30 CFR Part 62) [55] provides similar regulations as OSHA (above), but further requires simultaneous use of both earplugs and earmuffs when exposure levels exceed a time-weighted average of 105 dB-A. U.S. Department of Defense (2004; Instruction 6055.12, Hearing Conservation Program, March 5, 2004) [56]
Earplug. Pre-molded earplugs (left), formable earplugs (center), and roll-down foam earplugs (right) An earplug is a device that is inserted in the ear canal to protect the user's ears from loud noises, intrusion of water, foreign bodies, dust or excessive wind. Since they reduce the sound volume, earplugs may prevent hearing loss and tinnitus ...
OSHA's requirements state that when workers are exposed to noise levels above 90 A-weighted decibels (dBA) in 8-hour time-weighted averages (TWA), administrative controls and/or new engineering controls must be implemented in the workplace.
ITU-R 468 (originally defined in CCIR recommendation 468-4, therefore formerly also known as CCIR weighting; sometimes referred to as CCIR-1k) is a standard relating to noise measurement, widely used when measuring noise in audio systems. The standard, [ 1] now referred to as ITU-R BS.468-4, defines a weighting filter curve, together with a ...
