Sound Level Suppressors for Firearm Noise Reduction: Implications for Hearing Conservation

Sound level suppressors (also known as “silencers”) on firearms reduce—but do not eliminate—hazardous noise exposure, especially for AR-15 or similar semiautomatic rifles. At this time, the best advice is dual use of both HPDs and suppressors—particularly for those shooting weapons that produce dangerously high sound levels. For shooters who are reluctant to use HPDs, electronic HPDs should be considered as an option.
