Noise-Induced Hearing Loss Claims — Industrial Deafness Compensation

Understanding Noise-Induced Hearing Loss

The inner ear contains thousands of microscopic hair cells that convert sound vibrations into electrical signals sent to the brain. Prolonged exposure to high noise levels damages and ultimately destroys these cells. Unlike the cells of the skin or liver, cochlear hair cells in humans cannot regenerate once destroyed — the resulting hearing loss is permanent.

Noise-induced hearing loss typically develops gradually and is bilateral (affecting both ears). The earliest sign is usually a notching of the audiogram at 4kHz, which later broadens to affect the speech frequencies. Tinnitus — a continuous ringing, buzzing or whistling in the ears — is a common associated complaint and is taken into account separately when valuing the claim.

Industries Commonly Associated with NIHL Claims

• Engineering and metal fabrication — press shops, grinding, riveting and metal-cutting
• Manufacturing — general factory noise, textile mills, woodworking
• Construction — pneumatic tools, compactors, concrete-cutting
• Mining and quarrying — drilling, blasting, heavy plant
• Shipbuilding and docks — riveting, steel fabrication
• Agriculture — tractor and machinery noise
• Armed forces — firearms, aircraft, explosive ordnance
• Music industry — musicians, sound engineers, venue workers

Employer Duties Under the Noise Regulations

The Control of Noise at Work Regulations 2005 (replacing earlier 1989 regulations) impose a hierarchy of duties on employers. Where daily or weekly personal noise exposure reaches 80dB(A), employers must carry out risk assessments and provide hearing protection on request. At 85dB(A), the use of hearing protection is mandatory and designated hearing protection zones must be marked. Employers must also implement engineering and administrative controls to reduce noise at source where reasonably practicable, provide health surveillance, and provide training and information to workers.

Prior to 2005, the Noise at Work Regulations 1989 imposed similar (though slightly less stringent) duties. For exposures in the 1970s and 1980s, the courts have assessed liability against the knowledge and guidance available to employers at the time, using the leading case of Thompson v Smiths Shiprepairers as a benchmark.

The Audiogram Test in NIHL Claims

Audiometric testing is central to a noise-induced hearing loss claim. A pure-tone audiogram is carried out by a qualified audiologist to measure hearing thresholds across a range of frequencies. The degree of hearing loss is expressed in decibels at each frequency. An ENT specialist or audiologist acting as a medico-legal expert will assess the audiogram, the occupational exposure history, and any other factors that might explain the hearing loss (such as age, ear infection history or medication) to produce a report on causation and the degree of noise-related impairment.

Compensation for NIHL

Compensation is assessed on the degree of hearing impairment caused by noise exposure. The value also reflects whether tinnitus is present — tinnitus can range from a mild background noise to a severe, intrusive and disabling condition that significantly affects sleep, concentration and emotional wellbeing, and is valued accordingly. Special damages may include the costs of hearing aids and audiological services not available on the NHS.
