C weighted sound
WebC-weighted exposure level. If C-weighted levels are not available, 7 dB must be subtracted from the NRR to obtain the A-weighted sound level at the ear. Training and education sessions must be given at least annually to workers exposed above 85 dB(A). These sessions must include information on the effects of noise on hearing, the purposes and WebSound pressureor acoustic pressureis the local pressuredeviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unitof sound pressure is the pascal(Pa). [1] Mathematical definition[edit] Sound …
