Industrial deafness (noise-induced hearing loss) claims

Hearing loss from work creeps up so slowly that most people put it down to getting older. But if you spent years in a noisy factory, foundry, shipyard, mine, on a building site or in a band, and you now strain to follow conversation or live with constant ringing in your ears, the cause may be occupational noise — and that is something the law has required employers to control for decades.

What noise-induced hearing loss is

Loud sound destroys the tiny hair cells in the cochlea that convert vibration into the nerve signals we hear as sound. Unlike a cut or a fracture, these cells do not regenerate, so the damage is permanent and cumulative. NIHL typically affects the higher frequencies first, which is why consonants blur and conversation in background noise becomes exhausting long before quiet speech does. Many people also develop tinnitus — ringing, hissing or buzzing — which can be more disabling than the hearing loss itself because it interferes with sleep and concentration.

How workplace noise causes it — and the employer’s duty

The Control of Noise at Work Regulations 2005 require employers to assess noise, reduce it at source, and provide health surveillance where workers are exposed above the action values. The lower action value is a daily exposure of 80 dB(A) and the upper is 85 dB(A); above the upper value, hearing protection zones and mandatory protection apply, with an exposure limit of 87 dB(A) taking protection into account. Crucially, hearing protection is a last resort — employers must engineer noise down first. Earlier law going back to the 1960s placed similar duties on employers once the risks of industrial noise were well known. A claim generally succeeds where an employer exposed workers to harmful noise without assessment, controls, protection or hearing tests.

Proving an industrial deafness claim

The cornerstone is an audiogram — a hearing test whose pattern an ENT or audiology expert can read to distinguish noise damage from age-related loss, which have characteristically different shapes. Alongside it, a claim is built from your noise history (the jobs, machinery and years involved), evidence of the employer’s failings (no assessments, no protection, no tests), and records of any financial loss such as hearing aids. Colleagues from the same workplace can corroborate the conditions you describe.

Date of knowledge and time limits

The usual three-year limit runs from your date of knowledge — when you first reasonably linked your hearing or tinnitus to noisy work, often after a hearing test — not from the exposure itself. Because NIHL is gradual and easily mistaken for ageing, that date is frequently far later than people expect, so do not assume a claim from decades-old work is automatically too late. See our time-limits guide.

How much an NIHL claim is worth

General damages are assessed against the Judicial College Guidelines (17th edition, 2024). The figures below are illustrative ranges; severe tinnitus or total deafness in one or both ears attracts substantially higher awards.

Worked example

Brian worked 20 years in a press shop with no hearing protection until the late 1990s. He now has moderate high-frequency loss and persistent tinnitus that disturbs his sleep. His general damages are valued around £18,000 within the moderate bracket. Because he relies on digital hearing aids that need replacing every few years, a lifetime aids figure is added as special damages, lifting the claim well above the injury award alone.
