Hearing Protection After Military Hearing Damage: What Veterans Should Do Now

That distinction matters particularly for veterans who have hearing loss, tinnitus, hyperacusis, a history of acoustic trauma, continuing noisy employment, recreational shooting or noisy hobbies. NHS guidance tells people with hearing loss to use protection around loud noise while continuing normal communication and everyday activity, and HSE rejects a blanket approach — protection should be targeted at genuinely noisy tasks.

The short version

• Existing NIHL generally cannot be reversed, but further harmful exposure can still be avoided.
• Use protection for hazardous noise, not automatically for ordinary life.
• Reduce the noise itself before relying on earplugs or earmuffs. MOD policy calls hearing protection the "last line of defence"; HSE applies the same principle.
• The strongest protector is not automatically the best. Too much attenuation interferes with speech, hides warning signals, increases isolation and gets protection removed.
• HSE says occupational protection should generally avoid reducing noise below about 70 dB(A) at the ear.
• Correct fit matters enormously. Hair, hats, glasses and jewellery can break an earmuff seal, and an earplug that looks fitted may protect poorly.
• Wearing time matters as much as the device. HSE's own example: a protector expected to give 30 dB, worn about 95% of the time, may deliver only about half the expected effective attenuation.
• Firearms create intense impulse noise. Level-dependent electronic protectors can help, because they allow communication between shots while attenuating the shot itself.
• A sound moderator reduces firearm noise but does not make gunfire harmless or silent.
• Standard hearing aids are not hearing-protection PPE. Consumer noise-cancelling headphones are not either.
• If you work around noise and already have hearing loss, tell occupational health or whoever is responsible for noise safety.
• If ordinary sounds feel painfully loud, that may be hyperacusis — and NHS guidance warns specifically against wearing protection all day for it, because that can increase sensitivity.

Why protect hearing that is already damaged?

Because hearing loss is not all-or-nothing. Someone may already have permanent high-frequency NIHL and still retain useful hearing across much of the range. Further hazardous noise can add further injury. HSE describes occupational noise damage as permanent and incurable, and emphasises preventing additional exposure.

Hearing protection cannot restore hearing. Earplugs and earmuffs reduce sound reaching the ear; they do not reverse NIHL, damaged auditory structures, tinnitus or an old acoustic trauma. They are preventive equipment. Hearing aids do a different job — improving access to sound where hearing has already been lost.

The practical objective is protecting the remaining hearing, rather than assuming the damage is already done.

Control the noise before reaching for the ear defenders

Where you can control the noise itself, do that first: quieter equipment, more distance, less time near it, isolating noisy machinery, switching it off when not needed, avoiding unnecessary exposure.

This principle runs through both civilian and MOD policy. JSP 375 calls hearing protection the last line of defence and requires technical and organisational controls to be exhausted before PPE is relied on. HSE likewise says protection must not be used as an alternative to controlling noise by technical and organisational means.

Outside work you may not be able to redesign a rifle, a concert or someone else's workshop — but you can often change distance, duration, position, equipment, or whether you stay in the noisy area at all. Protection works best as part of a broader approach, not as permission to absorb unlimited noise.

When to wear it — and when not to

Use protection where noise is genuinely hazardous: firearms, power tools, grinding, hammering metal, noisy engines, chainsaws, workshop machinery, some motorsport, concerts and clubs. The risk depends on how loud and how long — and for very intense impulse noise, the duration can be extremely short and still matter.

Normal conversation, ordinary household sounds and most everyday environments do not need to be treated like a firing range. "My hearing is damaged, therefore I must protect my ears from everything" creates its own problems.

Consider someone working around vehicles. If their protection blocks so much sound that they cannot hear reversing warnings, shouted instructions or approaching machinery, one safety problem has simply been swapped for another.

HSE also rejects making protection compulsory during quiet periods just because part of a job is noisy. The principle is all of the dangerous exposure — not all of your waking life.

Fit and wearing time beat the number on the packet

Advertised attenuation assumes the protector is working as intended. An earplug that has not sealed leaves a path for sound. An earmuff sitting over spectacles, hair or a hat may have a broken seal. HSE specifically warns that long hair, woolly hats, spectacles and earrings can all interfere with performance, and that helmet-mounted earmuffs need the correct specific helmet-and-earmuff combination rather than any cup clipped to any helmet.

An earplug can look fitted and still protect poorly. HSE says plugs can be difficult to fit and may appear properly inserted while providing little protection — so practise fitting, follow the manufacturer's instructions, get help if needed, and keep reusable plugs clean. "I had plugs in" does not mean "I received the labelled attenuation".

Real-world protection is also often lower than laboratory performance because of fit, spectacles and other PPE. For occupational assessment HSE applies a 4 dB real-world derating to standard attenuation predictions in many circumstances.

So do not simply buy the protector with the highest SNR. The right protector is enough protection, reliably worn — not the biggest number on the packet. A protector that is painful or uncomfortable is unlikely to be worn consistently, and HSE recommends offering genuine choice for exactly that reason. The best theoretical protector is useless if it spends the noisy task in your pocket.

Inspect what you already own. Effective protection depends on intact seals, headband tension, cleanliness and no unauthorised modifications. A twenty-year-old pair of defenders is not automatically still delivering what is printed on the box. Disposable plugs should not be passed between people, and shared visitor earmuffs should be cleaned between users.

Earplugs or earmuffs?

The arms of spectacles can pass under an earmuff cushion and reduce the seal. That does not mean removing safety glasses so the earmuffs work — it means the equipment needs selecting as a compatible system. Protecting hearing should not create an eye-injury risk.

Shooting and impulse noise

Firearms create intense impulse noise — exactly the exposure where protection matters even though each sound is extremely brief. If you still shoot recreationally, professionally or in service: use appropriate protection, fit it before firing starts, keep it fitted throughout the firing exposure, and follow range and equipment safety requirements.

Level-dependent protection — sometimes called sound restoration — can work well here. HSE describes these as particularly suited to intermittent hazardous noise such as gunfire: they let the wearer hear normally during quiet periods while rapidly attenuating the shot. That addresses a genuine conflict between protection and situational awareness.

These are designed as hearing-protection equipment. That is different from putting on ordinary consumer headphones and assuming the electronics make them PPE. Occupational active-noise-reduction protectors also exist, generally earmuff-based, providing extra attenuation particularly at lower frequencies — but "has active noise cancellation" does not mean "certified hearing protection for gunfire or industrial noise".

A sound moderator reduces muzzle noise but does not make the discharge silent. Current UK government material says moderators reduce sound without eliminating the bullet's audible crack, and describes them as one way of helping protect shooters' hearing. Treat source-noise reduction and personal protection as complementary, not interchangeable.

Should you double up with plugs and muffs? Very intense environments sometimes need more protection than one device alone, and an NHS audiology page notes muffs can be combined with plugs for maximum protection. But that is an option, not a universal instruction — the right answer depends on the weapon, the environment, the measured peak noise, the protector specification and the other safety requirements.

Power tools, work and everyday noise

Grinders, saws, drills, hammering, garden machinery and compressors all deserve attention. Reduce risk with quieter equipment, more distance, shorter exposure and protection suited to the task. If a task is loud enough that you must shout to be heard at close range, treat that as the warning — rather than waiting for your ears to ring afterwards.

If you work in construction, engineering or a workshop, your employer has duties on occupational noise. HSE says protection should be provided and properly used where the exposure thresholds are reached, but that it remains secondary to control at source, and must not be used as an alternative to eliminating noisy tasks, quieter processes, engineering control, separating people from noise or quieter equipment. An employer cannot simply hand out earplugs and declare the problem solved.

If you already have hearing loss, tell the appropriate occupational-health or workplace safety service. That does not automatically mean you cannot work in noise — it means the risk should be managed knowing your actual hearing.

If your job depends on hearing warning sounds, tell whoever owns the noise risk assessment. The answer is neither "work unprotected so I can hear the alarm" nor "wear something so strong I cannot". HSE requires protection to preserve appropriate safety and communication, and level-dependent or communication-capable protectors may help. Note too that protectors with audio input expose the wearer both to attenuated environmental noise and to the reproduced audio, so communications systems need setting up so they do not themselves create excessive exposure at the ear.

For concerts and festivals, RNID recommends suitable earplugs, moving further from loudspeakers and taking regular quieter breaks. Musicians' or filtered earplugs reduce level while preserving more of the character of the music. For headphones, do not turn music up to overcome background noise — take breaks, use volume-limiting features, and note that noise cancellation helps mainly by reducing the *need* to turn the volume up.

Hearing aids are not PPE

A hearing aid is designed to make useful sound more audible. HSE identifies hearing-protection PPE as devices such as earplugs, earmuffs and semi-insert or canal protectors. Do not leave hearing aids in on the basis that "they already cover my ears".

If you wear hearing aids and are entering hazardous noise, ask your audiologist, occupational-health professional or a competent safety adviser how protection should be managed with your particular devices. Earmuffs over hearing aids may be possible depending on the aid type, cup size, fit, feedback and safety requirements — but the protection depends on getting the intended seal, and not every combination works. Where it matters occupationally, it should be assessed rather than improvised.

Where you need to hear speech while protected, there are protectors designed for it: level-dependent, flat-frequency-response, systems passing more mid-frequency information for speech, and protectors with communications facilities.

Sound sensitivity: the opposite mistake

If ordinary sound feels painfully or intolerably loud, that may be hyperacusis, and it needs a different approach from hazardous noise.

So someone with hyperacusis should still protect against shooting, grinding or hazardous machinery. The distinction is between genuinely hazardous noise and ordinary sound that merely feels uncomfortable because of sound sensitivity. If ordinary sound has become intolerable, ask for audiological assessment rather than progressively isolating yourself.

Tinnitus can push people the same way. After tinnitus following gunfire or machinery, caution is understandable — but there is a difference between wearing protection for hazardous exposures and reducing unnecessary noise, and wearing plugs for normal conversation or defenders around the house. If your tinnitus rises after noise, treat that as information about your exposure. If there is new sudden hearing loss, ear injury, vertigo or acute acoustic trauma, seek medical assessment rather than simply buying stronger earplugs — see acute acoustic trauma and tinnitus management.

How to tell whether your protection is enough

For occasional use, follow the product instructions, reputable safety guidance and the requirements of the activity or venue. For occupational or seriously repetitive exposure, use actual noise information, manufacturer attenuation data and competent calculation — HSE publishes hearing-protection calculators for exactly this.

If you have significant hearing in only one ear, it is sensible to protect what remains — but there is no separate decibel rule for it. Asymmetric hearing can bring particular communication and localisation needs, so selection may need to balance attenuation against warnings, communication and situational awareness.

If you are still serving, and if you have already claimed

JSP 375 applies to Defence personnel including reservists, and to Defence activities in the UK and overseas. Where exposure reaches the policy thresholds, controls, hearing-protection zones, PPE and health surveillance can all be required. Report new hearing symptoms, tinnitus, problems with protection, communication difficulties and poor equipment fit — and do not quietly improvise around military safety equipment when it does not work with your helmet, sights or communications. That compatibility problem is one the policy expressly recognises.

If you have already had an MOD hearing claim, the prevention advice does not change. A settled claim does not make further noise harmless, and protecting your hearing afterwards does not suggest the original injury was insignificant or that the earlier exposure did not happen. Healthcare and prevention continue after litigation.

Later noise can matter to a future claim, because an expert assessing hearing years afterwards may need to know about military exposure, civilian occupational noise, shooting, noisy hobbies and any later acoustic trauma. That is another reason to protect yourself and keep an accurate history. Do not deliberately stay exposed because you think avoiding noise might weaken evidence of the original injury.

A practical protection plan

1. Identify the genuinely noisy parts of your life — work, shooting, DIY, music, machinery.
2. Reduce the noise where you can — distance, quieter tools, shorter exposure, source control.
3. Use suitable protection — not automatically the strongest available.
4. Learn how it fits, especially earplugs.
5. Keep it on during the hazardous exposure — a few unprotected periods destroy much of the benefit.
6. Maintain it — seals, plugs, headband, cleanliness.
7. Preserve communication and safety — do not over-protect blindly.
8. Treat shooting as impulse noise and use protection designed for it.
9. Do not use hearing aids as substitute PPE.
10. Do not protect against ordinary life, especially where sound sensitivity is developing.
11. Get help where it is complicated — significant existing loss, hearing aids plus noisy work, sound sensitivity, or safety-critical communication.
