You used to hear the kettle click off from the next room. Now you do not. Your grandchildren’s voices sound clear when they are right beside you, then turn into a soft mumble the moment they walk away. You catch every third word in a busy cafe and fill in the rest from context. The doorbell, the smoke alarm beep, the high notes in a familiar song: all noticeably quieter than they used to be.
Most people put this down to getting older. Often, it is not. High-frequency hearing loss has a very specific shape on a hearing test, and that shape often points to noise damage from years, sometimes decades, earlier at work.
Around 15,000 people in Great Britain develop hearing problems caused or made worse by their job each year, and more than 2 million UK workers are still being exposed to unacceptable levels of noise on shift today (Health and Safety Executive, Noise-induced hearing loss in Great Britain, statistics for 2022/23 to 2024/25). Many of those affected do not realise the link until long after the damage has been done.
Why am I struggling with high-pitched sounds first?
The high-frequency hair cells in your inner ear are the first to be damaged by loud noise. These tiny sensory cells, called outer hair cells, sit in the part of the cochlea that processes high pitches. Once they are destroyed, they do not regenerate. That is why noise damage typically shows itself as trouble hearing consonants (“s”, “f”, “t”, “th”), children’s and women’s voices, and high-pitched alerts before it affects deeper sounds.
This is also why the world can sound loud enough overall, yet speech can feel mumbled. The vowels that carry volume are mostly low and mid-frequency. The consonants that carry meaning are mostly high-frequency. Lose the high frequencies and you lose clarity, even though loudness feels broadly normal.
How is noise damage different from age-related hearing loss?
The two conditions look distinct on an audiogram. Age-related hearing loss, known medically as presbycusis, produces a gentle, gradual slope downward across the high frequencies on both ears. Noise-induced hearing loss produces a different and very recognisable pattern: a sudden dip, called a “notch,” centred around 4,000 Hz (4 kHz), with hearing improving slightly again at 6,000 and 8,000 Hz before declining once more.
Audiology textbooks describe the 4 kHz notch as the signature pattern of noise damage. Where the notch is present in someone with a long history of noisy work, it is strongly suggestive of an occupational cause rather than ageing alone. In older workers, the notch can be partially obscured as age-related decline catches up with the surrounding frequencies, but a trained audiologist or medico-legal expert can usually still identify it.
What does the 4 kHz notch actually mean?
It means a specific part of the cochlea has taken disproportionate damage compared to the rest. That pattern almost never arises from ageing on its own. It does arise from prolonged exposure to noise at the levels typically found in factories, construction sites, printworks, foundries, shipyards, agricultural settings and music venues.
The Control of Noise at Work Regulations 2005 set the lower action value at 80 decibels (dB(A)) averaged across a working day, and the upper action value at 85 dB(A). For context, a busy main road sits at around 80 dB(A); a power drill at arm’s length, around 95 dB(A). Sustained exposure above 85 dB(A) without proper hearing protection causes the kind of cumulative damage that produces the 4 kHz notch on an audiogram years later.

Could past work be responsible if I don’t work there now?
Yes. Noise damage is cumulative and permanent. Hair cells destroyed in your twenties and thirties do not return when you move into a quieter role in your fifties or sixties. The hearing difficulty you notice now may be the long delayed consequence of work you did decades ago, in a different industry, for an employer who no longer exists.
This is one of the reasons that occupational hearing loss is so often under-recognised. The exposure happened a long time ago. The symptoms creep in slowly. By the time the difficulty becomes obvious, the connection to historical work feels like ancient history rather than a current problem.
It is not. The law explicitly recognises that you cannot reasonably be expected to act on hearing damage you did not yet know was caused by work.
Can I still bring a claim if my noisy job ended decades ago?
In many cases, yes. Personal injury claims in England and Wales must usually be brought within three years, but for industrial disease the three-year clock does not start running on the day you were exposed. It starts on your “date of knowledge” under sections 11 and 14 of the Limitation Act 1980.
Date of knowledge is the point at which you first knew, or should reasonably have known, three things together:
- That your hearing loss was significant
- That it was attributable to your work
- The identity of the responsible employer
For most people with noise-induced hearing loss, that point is a recent audiology appointment or GP visit, not the date they were exposed to the noise. Even if the exposure was in the 1980s or 1990s, your case may still be in time today.
What does the law require employers to do?
Under the Control of Noise at Work Regulations 2005, your employer is legally required to:
- Assess workplace noise levels (Regulation 5)
- Reduce noise at source where reasonably practicable (Regulation 6)
- Provide suitable hearing protection where exposure cannot be reduced below 85 dB(A) (Regulation 7)
- Make sure protection is actually worn and maintained (Regulation 8)
- Provide regular hearing tests (health surveillance) for workers exposed above the upper action value (Regulation 9)
- Inform, instruct and train workers about noise risks (Regulation 10)
Where these duties were breached and you have hearing damage as a result, you may have grounds for a hearing loss claim.
WE Solicitors’ experience
WE Solicitors has handled industrial disease and hearing loss claims for over 24 years from our offices in the North West, with clients across England. We currently act for workers from a range of historically noisy industries, including the printing trade, who developed noise-induced hearing loss after decades of exposure that was only properly identified years later.
Every case is handled on a No Win, No Fee basis. There is nothing to pay up front and nothing to pay if your claim does not succeed.
Frequently asked questions
Do I have to be totally deaf to claim?
No. Compensation is available across the full range, from slight noise-induced hearing loss with occasional tinnitus through to total deafness with severe tinnitus. What matters is that the damage is measurable on an audiogram and linked to historical noise exposure at work.
What if I never had a hearing test at work?
Many older workers were never offered audiometry, particularly before the 2005 Regulations tightened. The absence of historical hearing tests does not weaken your claim. A current audiogram, combined with your work history, is usually enough for a medical expert to assess the likely occupational contribution.
Could it be something other than noise damage?
Possibly. A range of conditions can affect hearing, including ear infections, certain medications and genetic factors. A medico-legal audiologist will rule these out as part of any claim. The presence of a 4 kHz notch in someone with a long history of noisy work is, however, a strong indicator of occupational cause.
Will making a claim affect my old employer’s business?
Claims are made against the employer’s liability insurer at the time you worked there, not the company itself. Your former employer does not pay personally. WE Solicitors routinely traces historic insurers, including for companies that have long since closed.
How do I find out if I have a claim?
Call 0800 294 3065 for a free, no obligation conversation, or use our online contact form. We will talk through your work history and current symptoms and tell you honestly whether a claim is likely to be worth pursuing.
