Hearing protection and decibel reduction
Hearing protection and decibel reduction
(OP)
We use ear plugs and ear muffs in combination at more than one process. Neither type of protection has a high enough NRR to bring the decibels down to a safe level, so we combine them. Does anyone know if this is an approved practice or what could be used instead? Is this issue cited specifically in OSHA, NIOSH, ANSI, etc?

chicopee, I've never seen any documentation that states hearing protection is not effective over 120 dB. There are many industrial/construction/military sites that have >120 dB and not had noise induced hearing loss. If you know of any published reports, please post. Thanks.
