Sounds at or below 70 A-weighted decibels (dBA), even after long exposure, are unlikely to cause hearing loss. However, long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. The louder the sound, the shorter the amount of time it takes for NIHL to happen.

What dB rating should I use for shooting?

28 to 31A product with a 28 to 31 NRR is recommended for indoor shooting. There are two different kinds of hearing protection, ear plugs and ear muffs. The National Institute for Occupational Safety and Health actually recommends using both earplugs and earmuffs together when shooting.

Multiple sources identify this level at 194 dB SPL peak re 20 µPa.
