Military hyperacusis claim: sound sensitivity, noise exposure, and compensation
TL;DR
- A military hyperacusis claim is a civil claim against the MoD for abnormal sensitivity to everyday sounds caused by noise exposure during service. Hyperacusis frequently accompanies tinnitus and can be claimed alongside or independently of noise-induced hearing loss.
- Hyperacusis most commonly follows acute acoustic trauma such as an IED blast, weapon discharge close to the ear, or demolition event. It can also develop from cumulative noise exposure where cochlear damage alters how the auditory system processes sound.
- The MoD owed a duty to prevent noise exposure causing hyperacusis to the same extent it owed a duty to prevent hearing loss and tinnitus. The legal route is identical.
- Matrix Agreement registration deadline: 31 July 2026. A free eligibility assessment carries no obligation to proceed.
Hyperacusis is a condition in which everyday sounds that most people tolerate without difficulty become painful or distressing. Conversations in busy rooms, traffic noise, a television at normal volume, or a dropped object can trigger a disproportionate and sometimes debilitating response. For veterans whose hyperacusis developed during or after service, a military hyperacusis claim against the Ministry of Defence may be available where the condition was caused by noise exposure the MoD failed to prevent.
This page explains what hyperacusis is, how it arises from military service, how a claim is established, and what compensation is available.
What is a military hyperacusis claim?
A military hyperacusis claim is a civil negligence claim against the Ministry of Defence for hyperacusis caused or materially contributed to by excessive noise exposure during service, on the basis that the MoD breached its duty to protect service personnel from harmful noise.
The legal framework is the same as for tinnitus and noise-induced hearing loss claims. The Crown Proceedings Act (Armed Forces) 1987 enables civil claims against the MoD for service injuries sustained on or after 15 May 1987. The 2005 Regulations reinforce the duty with specific obligations to assess noise levels, provide suitable protection, and enforce its use. Hyperacusis arising from a breach of those obligations is compensable in the same way as hearing loss and tinnitus. The conditions page on this site sets out the clinical profile of hyperacusis and the other conditions recognised in military hearing loss claims.
All service branches are covered: British Army, Royal Navy, Royal Marines, Royal Air Force, and Reserve forces.
What causes hyperacusis in military service?
Hyperacusis in military service is caused by cochlear and central auditory system damage from excessive noise, which alters the brain's calibration of sound intensity.
The condition most commonly follows acute acoustic trauma: a single extremely loud event such as an IED detonation, a weapon firing close to an unprotected ear, a demolition charge at short range, or a grenade detonating nearby. In those cases, the pressure wave and acoustic shock can alter cochlear hair cell function and the central gain processes that regulate how sound is perceived. Survivors of IED blasts who develop hyperacusis typically notice the onset within hours or days of the incident: everyday sounds that previously caused no distress become intolerable.
Hyperacusis can also develop from cumulative noise exposure over a career of range work, vehicle operations, or aircraft maintenance. In those cases, the progressive cochlear damage gradually shifts the auditory system's sensitivity threshold. The veteran may notice increasing discomfort in noisy environments before the condition is formally identified as hyperacusis.
Hyperacusis is frequently associated with tinnitus and may co-exist with noise-induced hearing loss. A veteran may have all three conditions from the same noise exposure. Each is separately compensable, and a claim can be brought for all three together.
Can you claim for hyperacusis without hearing loss?
Yes. A military hyperacusis claim can succeed without measurable hearing loss on an audiogram, just as a tinnitus claim can succeed without NIHL.
Hyperacusis is a disorder of sound tolerance, not of hearing threshold. A veteran with hyperacusis may hear sounds at normal or near-normal thresholds but experience pain or distress at intensities that most people tolerate. The absence of a hearing loss does not affect the validity of a hyperacusis claim: the condition arises from a different mechanism and is assessed by reference to its own clinical presentation and impact on the veteran's daily life. What is required is a credible account of onset connected to service noise exposure, supported where possible by service records, audiological assessment, and any medical or GP notes recording the condition.
Abbott and Others v Ministry of Defence [2026] EWHC 941 (KB) confirmed the principle for tinnitus that subjective noise-related conditions can succeed without audiogram evidence of threshold shift. That reasoning applies equally to hyperacusis.
What is the difference between hyperacusis and tinnitus?
Hyperacusis and tinnitus are related but distinct conditions that are assessed and compensated separately in a military hearing loss claim.
Tinnitus is a perceived sound with no external source: ringing, buzzing, hissing, or pulsing that the veteran experiences internally. It can be constant or intermittent, and its impact ranges from mild background noise to severely disruptive. Hyperacusis is an abnormal sensitivity to external sounds that are actually present: the issue is not a phantom sound but an abnormal and painful response to real sounds in the environment.
The two conditions frequently co-exist. A veteran with both tinnitus and hyperacusis from the same service noise exposure can bring a combined claim covering both conditions. The Judicial College Guidelines assess them separately and apply different brackets for each. Where both are present, the overall award reflects the combined impact on the veteran's daily life, work, sleep, and social functioning.
How is a military hyperacusis claim proved?
A military hyperacusis claim is proved through a combination of service records documenting noise exposure, audiological assessment, and clinical evidence of the condition and its impact.
Service records establish the nature and intensity of the noise exposure: the weapons fired, the demolition events attended, the vehicles operated, or the aircraft maintenance carried out. An independent audiologist assesses the veteran's hearing and sound tolerance, producing a report that identifies hyperacusis and links it to the exposure history where the evidence supports that conclusion. A detailed account of the onset and progression of symptoms, including how hyperacusis affects daily activities, relationships, and work capacity, provides the basis for the damages assessment.
Where hyperacusis followed a specific incident such as a blast or weapon discharge, the link between the event and the condition onset is often direct and clinically straightforward. Where it developed gradually from cumulative exposure, the causation analysis follows the same approach as for cumulative NIHL.
How much does a military hyperacusis claim pay?
A military hyperacusis claim's general damages are assessed against the Judicial College Guidelines by reference to the severity of the condition and its impact on the veteran's life. The compensation amounts page on this site sets out the full JCG brackets for hearing conditions including tinnitus, NIHL, and total deafness.
Hyperacusis that prevents employment in noisy environments, curtails social activities, or requires ongoing clinical treatment attracts higher general damages than a mild form that causes occasional discomfort. Where hyperacusis co-exists with tinnitus and NIHL, the combined award reflects all three conditions. Special damages cover the financial consequences: private sound therapy, cognitive behavioural therapy for sound sensitivity, tinnitus retraining therapy, acoustic therapy devices, and any loss of earnings where the condition prevented work in certain environments.
The 18th edition of the Judicial College Guidelines, published in April 2026, carries an uplift across hearing and noise-related condition categories. Confirm current figures with a specialist before relying on them for any individual estimate.
Hyperacusis, tinnitus, and NIHL in the same claim
Many veterans with hyperacusis also have tinnitus and some degree of noise-induced hearing loss from the same service exposure. A single claim can cover all three conditions, and the compensation is assessed for each on its own facts without double-counting the same underlying noise exposure.
Where all three conditions are present, the claim is built around the full audiological picture: the hearing threshold results under rM-NIHL, the tinnitus assessment, and the hyperacusis evaluation. The solicitor instructs an audiologist experienced in all three presentations. Each head of claim is valued separately and the total settlement reflects the combined impact.
For veterans unsure whether they have hyperacusis in addition to tinnitus or hearing loss, the free eligibility assessment is the starting point. A specialist will identify which conditions should be included in the claim based on the veteran's description of their symptoms.
Starting your military hyperacusis claim
If you have abnormal sensitivity to sound that you believe is connected to noise exposure during service, a free eligibility assessment confirms whether a military hyperacusis claim is available to you.
The assessment covers your service history, the noise events you experienced, and your current symptoms. It takes around 15 minutes and commits you to nothing. If your claim has merit, an independent audiologist carries out a hearing and sound tolerance assessment, and service records are obtained from the relevant records office. Most claims settle without going to court. You pay nothing upfront and nothing if the claim is unsuccessful.
The Matrix Agreement registration deadline of 31 July 2026 means acting now preserves the scheme's procedural advantages. You can check your eligibility criteria on this site at no cost, or begin directly with a free assessment online or by telephone.
