Quick Answer
Hunters can still risk losing hearing protection benefits with suppressors, but at a much lower level than traditional firearms. This is because suppressors reduce the loud noise but do not eliminate it entirely. Proper use of hearing protection is still essential.
Suppressor Effectiveness
Suppressors, also known as sound moderators, can reduce the noise level of a firearm by up to 30 decibels (dB). For example, a .308 Winchester rifle can produce a noise level of around 160 dB without a suppressor. With a suppressor, this noise level can be reduced to around 130 dB, which is still loud enough to cause hearing damage if proper hearing protection is not used. The National Institute for Occupational Safety and Health (NIOSH) recommends a maximum sound exposure level of 85 dB per 8-hour period.
Hearing Protection with Suppressors
Even with a suppressor, it is essential to use hearing protection to prevent hearing damage. The type of hearing protection used will depend on the specific application and the level of noise reduction required. Electronic ear muffs or earmuffs with active noise reduction (ANR) technology can be effective in reducing sound levels to safe levels. For example, the Howard Leight Impact Sport Electronic Earmuff can reduce sound levels by up to 22 dB, making it an effective choice for use with suppressors.
Suppressor Maintenance and Upgrades
Proper maintenance and upgrades of suppressors are crucial to ensure they continue to perform effectively. Regular cleaning and inspection of the suppressor can help maintain its effectiveness and prevent damage. Upgrading to a more advanced suppressor design or materials, such as titanium or stainless steel, can also improve its performance and durability. For example, the SilencerCo Omega 45 suppressor features a titanium construction and a proprietary flash hider that reduces muzzle flash and improves visibility.
