Ringing in the ears after shooting a firearm without adequate hearing protection typically lasts anywhere from a few minutes to a couple of days, depending on the intensity and duration of exposure. A single gunshot can produce sound levels well above 140 decibels at the shooter’s ear, far exceeding the threshold for immediate damage to the delicate structures inside the cochlea. If the ringing fades completely within 24 to 48 hours, the exposure likely caused a temporary threshold shift rather than permanent injury, but that reassuring timeline hides a more complicated picture involving damage that standard hearing tests may not detect.
Why Gunfire Is So Dangerous to Your Ears
Firearms produce what acousticians call impulse noise: an extremely loud, extremely short burst of sound pressure. An unsuppressed AR-15 rifle, for example, generates peak sound pressure levels that remain above 140 dB even at the shooter’s ear with a suppressor attached in most ammunition configurations.1PubMed. Differential effects of suppressors on hazardous sound pressure levels generated by AR-15 rifles: Considerations for recreational shooters, law enforcement, and the military For context, 140 dB is the widely accepted ceiling above which a single impulse can cause immediate cochlear damage. Many common firearms blow past that mark comfortably.
The reason impulse noise is worse than, say, standing near a loud speaker for the same total energy comes down to how the ear’s protective mechanisms work. Your middle-ear muscles can contract reflexively to dampen sustained loud sound, but a gunshot arrives and peaks in under a millisecond. The reflex simply cannot engage fast enough. The full force of the pressure wave reaches the cochlea unfiltered, smashing into rows of sensory hair cells that convert sound vibrations into nerve signals.
Indoor shooting ranges amplify the problem. Reflections off walls and ceiling create reverberant energy that adds to each blast and prolongs the time the ear spends under hazardous pressure. Research into hearing protector performance at indoor ranges found that the combination of peak pressure and sustained equivalent noise levels was severe enough that several commonly sold earmuffs and earplugs did not bring exposure below safe limits.2PubMed Central.

Temporary Ringing Versus a Sign of Lasting Damage
The ringing you hear after a gunshot is tinnitus, and in the acute phase it is part of what audiologists call a temporary threshold shift (TTS). Your hearing sensitivity drops, sounds seem muffled, and a high-pitched tone fills one or both ears. In most cases of mild exposure, TTS resolves within hours. After heavier exposure, it can take a day or two. If your hearing and the ringing return fully to normal within roughly 48 hours, the conventional view has been that no permanent harm was done.
That conventional view is increasingly contested. Research shows that even when hearing thresholds recover to pre-exposure levels on a standard audiogram, the synapses connecting hair cells to auditory nerve fibers can be permanently destroyed. This phenomenon means you can pass a hearing test and still have real, measurable auditory dysfunction, particularly in noisy environments where your brain needs every available nerve fiber to parse speech from background sound.3PubMed Central. Temporary and Permanent Noise-induced Threshold Shifts: A Review of Basic and Clinical Observations Researchers suspect that cumulative synapse loss from repeated “temporary” exposures may accelerate age-related hearing decline years later.
If ringing persists beyond 48 to 72 hours, or if it fades but returns, or if you notice that speech clarity in noisy rooms has gotten worse even though quiet sounds seem fine, these are signs that damage has crossed the line from temporary to permanent. A permanent threshold shift (PTS) means hair cells or their neural connections are gone for good, because unlike some other tissues, the mammalian cochlea does not regenerate its sensory cells.
What the Recovery Pattern Looks Like
Recovery from impulse noise does not follow a smooth, predictable curve. Animal studies of gunshot-like impulse exposure have shown that the pattern of threshold recovery is non-monotonic, meaning hearing can fluctuate unpredictably during the days after exposure rather than improving steadily.4PubMed. Changes in the stereocilia and non-monotonic pattern of threshold shift after exposure to impulse noise You might feel better in the morning and worse by evening, or notice the ringing fade and then briefly return. This is different from recovery after exposure to steady industrial noise, which tends to follow a more gradual downward slope.
Community-based research on people with new-onset tinnitus (from various causes, not exclusively gunfire) has found that tinnitus loudness and distress tend to be highest right around the time of onset and decrease over the first several months. In one longitudinal study, psychoacoustically matched tinnitus loudness dropped substantially between the acute phase and the six-month follow-up.5PubMed Central / Elsevier. Short- and long-term changes in auditory sensitivity and tinnitus distress between acute and chronic tinnitus: Longitudinal observation in a community-based sample For shooters whose ringing lasts weeks rather than hours, this trajectory offers some reassurance: the brain does adapt, even when the underlying damage persists. The tinnitus often becomes less intrusive over time even if it does not disappear entirely.
What to Do in the First 24 to 48 Hours
If your ears are ringing after shooting, the single most important step is to stop any further noise exposure immediately. Every additional shot compounds the injury. Leave the range, put in hearing protection if you must stay in the area, and give your ears silence. There is no home remedy that will reverse cochlear damage, but minimizing additional insult gives your hair cells and synapses the best chance of recovering whatever function they can.
During this period, avoid loud music, concerts, power tools, and anything else that elevates your noise exposure. Think of the cochlea like a sunburn: the tissue is inflamed and more vulnerable to additional harm. Even sounds that would normally be safe can pile on and push a temporary shift into a permanent one.
Some people find the ringing more distressing at night when background noise drops away. White noise from a fan or a sound machine can help mask the tinnitus and make sleep easier while you wait for recovery. This is symptom management, not treatment, but sleep deprivation makes everything worse, including your perception of tinnitus.
When You Should See a Doctor
If ringing, muffled hearing, or a feeling of fullness in the ear persists beyond 48 to 72 hours, you should see a physician, ideally an otolaryngologist or audiologist. Speed matters here. Sudden sensorineural hearing loss, defined clinically as a drop of 30 dB or more over three adjacent frequencies within 72 hours, is treated as a medical urgency. Guidelines recommend that diagnosis and treatment should not be delayed for audiometric testing or specialist referral if the presentation is clear.6PubMed Central. Sudden Sensorineural Hearing Loss: Primary Care Update
The standard first-line treatment is a course of oral corticosteroids, typically prednisone, started as soon as possible. The theory is that steroids reduce cochlear inflammation and swelling, giving damaged but not yet dead hair cells a chance to survive. The window for this intervention is narrow; most clinicians want treatment to begin within the first two weeks after injury, and sooner is considered better. A randomized trial comparing high-dose intravenous and oral steroid regimens against a standard lower-dose oral course for sudden hearing loss found no clear advantage to escalating the dose, and the higher-dose groups experienced more side effects.7PubMed. High-Dose Glucocorticoids for the Treatment of Sudden Hearing Loss The takeaway is that starting standard-dose steroids promptly appears to be more important than chasing a higher dose.
Hyperbaric oxygen therapy is another option that some military and specialized centers offer for acute acoustic trauma. A Japanese military study spanning two decades of treating service members with shooting-related hearing injuries found that hearing improved in about 70% of treated ears, and over 80% of ears showed improvement in subjective symptoms like tinnitus and aural fullness.8PubMed Central. Utility of Hyperbaric Oxygen Therapy for Acute Acoustic Trauma: 20 years’ Experience at the Japan Maritime Self-Defense Force Undersea Medical Center Hyperbaric oxygen is not widely available and is not standard care in most civilian settings, but if you have access to a facility and the injury is recent, it is worth discussing with your doctor.
Screening That Goes Beyond the Standard Hearing Test
A standard audiogram measures how quiet a tone you can detect at various frequencies. It is good at catching large threshold shifts but can miss subtler damage, especially the synapse loss described earlier. Researchers have found that transient evoked otoacoustic emissions (TEOAEs), a test that records faint sounds produced by healthy outer hair cells in response to clicks, can detect functional changes in shooters even when their audiograms look normal. In one study, only about 40 to 47% of ears passed the TEOAE screen after high-intensity noise exposure from shooting, a significant drop compared to pre-exposure results, despite audiometric thresholds remaining within normal limits.9Russian Otorhinolaryngology. Use of transient evoked otoacoustic emissions as a hearing screen after high-intensity noise exposure
If you are a regular shooter and want a more complete picture of your auditory health, ask your audiologist about otoacoustic emission testing and speech-in-noise testing in addition to the basic audiogram. These measures are more sensitive to early damage and can flag problems before you notice them in daily life.
Does Hearing Protection Actually Prevent Ringing?
It can, but the type of protection matters enormously. Research on firearm users who reported wearing hearing protection consistently found no statistically significant differences in cochlear or neural auditory function compared to non-shooting controls, and over 90% of the firearm users in that study said they wore protection either all the time or almost all the time.10PubMed Central. Evaluation of hidden hearing loss in normal-hearing firearm users Consistent protection works. The problem is that not all protection is equal to the task.
Studies of impulse noise attenuation have found that standard foam earplugs alone provide roughly 16 dB of reduction against rifle fire, and thin-profile earmuffs do slightly better at around 17 dB, but neither is sufficient on its own for rifle shooting.11PubMed. Physical characteristics of gunfire impulse noise and its attenuation by hearing protectors Large-volume earmuffs perform better, and for high-caliber or large-bore firearms, the recommendation is to double up with earmuffs over earplugs. Pistol and shotgun shooters can often get adequate protection from earmuffs alone, but rifle shooters and anyone using large-caliber weapons should treat dual protection as the baseline rather than the exception.
Electronic earmuffs, which amplify quiet sounds while clamping down on loud impulses, have become popular for good reason: they let you hear range commands and conversations while still blocking the blast. However, their Noise Reduction Rating (NRR) varies widely by model, and the NRR printed on the box tends to overstate real-world attenuation. If you use electronic muffs, pairing them with foam inserts underneath is a practical way to close the gap.
How Suppressors Change the Equation
Firearm suppressors (often called silencers, though they do not actually silence anything) reduce the peak sound pressure of a gunshot by roughly 17 to 24 dB at the shooter’s ear, with even greater reductions for an instructor or bystander standing behind the shooter.12PubMed Central. The reduction of gunshot noise and auditory risk through the use of firearm suppressors and low-velocity ammunition Combined with subsonic ammunition, some suppressor configurations can push sound levels near or below the 140 dB damage threshold.1PubMed. Differential effects of suppressors on hazardous sound pressure levels generated by AR-15 rifles: Considerations for recreational shooters, law enforcement, and the military
Suppressors are not a replacement for ear protection, though. With supersonic ammunition, the sonic crack of the bullet itself adds noise that the suppressor cannot eliminate, and levels at the ear often remain above safe thresholds. Think of a suppressor as one layer in a system: it brings the peak exposure closer to what hearing protection can handle on its own, making the overall situation considerably safer. A suppressed rifle plus earmuffs is a meaningfully different exposure from an unsuppressed rifle plus the same earmuffs.
Why Some People’s Ears Ring Longer Than Others
Two people can fire the same gun at the same range and walk away with very different outcomes. Individual susceptibility to noise-induced hearing loss has been recognized for decades, and the explanations remain partly unresolved. Researchers have pointed to differences in the acoustic reflex (how quickly and strongly the middle-ear muscles contract), efferent nerve function (how the brain actively protects the cochlea by sending dampening signals back down), and prior noise exposure history as factors that vary enough from person to person to account for large differences in vulnerability.13PubMed. Individual susceptibility to noise-induced hearing loss: an old topic revisited
Prior hearing loss can paradoxically change the picture in a counterintuitive way. Animal research suggests that ears that already have some permanent hearing loss from a first noise exposure may actually show less additional damage from a second exposure, likely because the effective intensity reaching the already-damaged cochlea is reduced.14PubMed. Effect of an initial noise induced hearing loss on subsequent noise induced hearing loss This does not mean a pre-existing loss is protective in any useful sense; it means there is less left to destroy. But it helps explain why a first unprotected shooting exposure can feel so much worse than subsequent ones, and why beginners at the range sometimes experience more dramatic ringing than seasoned shooters who may already have baseline losses they have adapted to.
Certain medications can also raise your vulnerability. Aminoglycoside antibiotics (used for serious infections) and cisplatin (a chemotherapy drug) are known ototoxins, and research has shown that even moderate noise levels potentiate the damage caused by these drugs, making the combined effect on the cochlea worse than either exposure alone.15PubMed Central. Potentiation of Chemical Ototoxicity by Noise If you are on any medication flagged as potentially ototoxic, your threshold for what counts as “safe” noise is effectively lower.
Tinnitus, Hyperacusis, and the Psychological Toll
Persistent tinnitus after shooting is not just an auditory problem. It spills into sleep, concentration, mood, and work performance. Survey data from military service members and veterans found that tinnitus had measurable effects on job performance, concentration, anxiety, depression, and sleep across both active-duty and veteran populations.16PubMed. Impact of Tinnitus on Military Service Members
A related condition that sometimes accompanies noise-induced tinnitus is hyperacusis, an abnormal sensitivity to everyday sounds that most people tolerate easily. In a large survey study, people who met the threshold for hyperacusis had roughly ten times the odds of also reporting tinnitus. Interestingly, after adjusting for anxiety and depression, the hyperacusis label itself lost statistical significance as a predictor of tinnitus severity, while affective states like anxiety and depression remained significant.17Taylor & Francis Online (International Journal of Audiology). An online survey study of the association between tinnitus and hyperacusis using validated questionnaires The practical implication is that if your post-shooting ringing is accompanied by heightened anxiety, depressed mood, or growing sensitivity to sound, treating the psychological dimension is not optional. Cognitive behavioral therapy for tinnitus, mindfulness-based approaches, and in some cases medication for anxiety or depression can substantially reduce the distress component even when the tinnitus signal itself remains.
Can Supplements Protect Your Ears Before a Shoot?
The idea that you could pop a pill before heading to the range and reduce your risk of noise damage is appealing, and it has a real basis in biology. Noise injury to the cochlea involves oxidative stress: the hair cells produce reactive oxygen species under mechanical assault, and these molecules trigger cell death pathways. That has led researchers to test antioxidant compounds like N-acetylcysteine (NAC), coenzyme Q10, vitamin E, and various polyphenols as pre-exposure prophylaxis.18PubMed Central. Antioxidant Therapy as an Effective Strategy against Noise-Induced Hearing Loss: From Experimental Models to Clinic
Animal studies have shown real protective effects for several of these compounds, with NAC being the most widely studied. A handful of clinical trials in humans have also shown promising results, particularly with NAC and magnesium. However, the evidence in humans is still thin compared to the animal data, doses and timing vary across studies, and no antioxidant regimen has been formally recommended by any major audiology or medical body as standard prevention. If you are interested in trying NAC or magnesium before range sessions, the risk is low and the biological rationale is sound, but do not treat it as a substitute for hearing protection. Think of it as a seatbelt backup, not the car’s brakes.
The Asymmetry Problem and Which Ear Rings More
Shooters frequently notice that one ear rings more than the other. This is not random. For a right-handed rifle shooter, the left ear is typically closer to and more directly exposed to the muzzle blast, while the right ear gets some acoustic shadow from the head itself and from the stock of the rifle. The difference in peak pressure between the two ears can be substantial. Handgun shooters see less asymmetry because the arms-extended firing position places both ears at roughly equal distances from the muzzle, but even here, the dominant hand’s side tends to be slightly more shielded.
Over years of shooting, this asymmetry accumulates. Audiologists who test long-time recreational shooters often find a characteristic notch in hearing sensitivity around 4,000 to 6,000 Hz that is deeper in the ear closer to the muzzle. If you notice persistent ringing concentrated in one ear after shooting, mention the asymmetry to your doctor, since one-sided hearing symptoms can also signal conditions unrelated to noise (such as an acoustic neuroma), and the distinction matters for determining what further evaluation is needed.
