Preventing acoustic trauma from gunfire means wearing hearing protection for every shot, because one unprotected shot above 140 dB peak can cause permanent hearing loss or tinnitus; electronic protection lets hunters hear game while it blocks the blast.
Most hunters still go without it. That gap, and the reason for it, is most of what this article is about.
How loud gunfire is
Peak sound levels from firearms range from roughly 140 to 175 dB. Most recreational firearms, leaving aside small-calibre .17 and .22 rifles and air rifles, produce 150 to 165 dB peak, and the American Speech-Language-Hearing Association (ASHA) notes that higher-calibre rifles can exceed 175 dB.
The benchmark those numbers are measured against is 140 dB peak. OSHA's workplace noise standard says impulse noise should not exceed it, because of the risk of permanent hearing damage, and ASHA's guidance is that exposure above 140 dB peak can permanently damage hearing even from a single occurrence. Most firearms are above that line, which is why one unprotected shot carries real risk, not only a lifetime of range sessions. People who shoot without protection, or with protection that does not fit, can get hearing loss or tinnitus from as little as one shot.
Why hunters specifically are under-protected
Studies summarised by ASHA found that only about half of target shooters wear hearing protection all the time when practising, and 70% to 80% of hunters never wear it. The reason hunters give is that protection stops them hearing approaching wildlife.
That is a real tradeoff, not carelessness, which is exactly why the answer is not "always wear standard earmuffs" but protection designed for this use (see below).
A distinctive pattern: asymmetric hearing loss
Gunfire damage is often worse in the ear closer to the muzzle. With rifles and shotguns, right-handed shooters typically lose more hearing in the left ear, and left-handed shooters in the right. If your tinnitus or hearing loss is notably worse on one side and you have a shooting or hunting history, that asymmetry is a recognised pattern.
It is still worth reporting rather than explaining away yourself. European radiology recommendations list one-sided or asymmetric tinnitus, and asymmetric hearing loss, among the situations where an MRI is indicated, so the shooting history belongs in the conversation as information for the clinician, not as the conclusion. Do you need a scan for tinnitus? sets out those criteria.
What helps without sacrificing situational awareness
- Electronic hearing protection is the practical answer to the hunter's dilemma. These earmuffs or earplugs let soft and ordinary sounds through (footsteps, wildlife, conversation) and switch to protection when they detect a sudden loud impulse like a gunshot, so you keep situational awareness without taking the muzzle blast unprotected. Electronic earplugs come in custom-made and one-size styles.
- Fit matters as much as the product. Protection has to be properly selected and fitted to reduce loud sounds effectively; ASHA warns that if protection fits badly, loud sounds are not reduced and hearing damage can still result. Choosing earplugs covers what to look for, and an audiologist can advise on shooting-specific options.
- Suppressors, where legal, reduce peak levels, but by less than their reputation suggests. Measurements by NIOSH researchers found reductions of 17 to 24 dB at the shooter's ear, and a study of nine AR-15 rifles with 14 suppressors found 7 to 32 dB across conditions, with levels near the shooter's right ear staying above 140 dB peak in most combinations. The NIOSH researchers concluded that firearm users should always wear hearing protection when target shooting or hunting, suppressed or not.
- Double protection (earmuffs over earplugs) for high-exposure situations such as indoor ranges, where sound reflecting off the walls adds to the exposure beyond the muzzle blast itself. If you shoot indoors, ASHA suggests choosing a range that has been acoustically treated for reverberation.
- Choices that lower the dose. ASHA's advice includes smaller-calibre firearms for target practice and hunting, single-shot firearms rather than lever-action, pump or semi-automatic guns, and avoiding shooting in enclosed spaces.
- Distance, where the activity allows it. The distance between shooters is one of the factors that shapes risk; sound drops several decibels each time distance from the source doubles, though less predictably with several people firing close together, as at a group range session.
What repeated exposure adds up to
Firearm users tend to develop high-frequency hearing loss, which makes speech sound unclear rather than simply quiet. Even exposure below 140 dB, if frequent, follows the same cumulative pattern as any other noise-induced tinnitus: a day at an indoor range with dozens of shots, even with protection that is not perfectly fitted, is a very different exposure from a single hunting shot. Audiologists see more noise-induced hearing loss during hunting season, when hunters and bystanders are exposed to gunfire, which is a reasonable prompt to get a baseline hearing test if you shoot or hunt regularly and have not had one.
