Noise induced hearing loss claims




Historical perspective
The first controlled epidemiological study into the effects of occupational noise was conducted by Thomas Barr in 1886.

A description of the medical condition
How Does the Ear Perceive Sound? The ear consists of 3 basic parts; the outer ear, the middle ear and the inner ear.

Medical causation issues
All claims for noise induced hearing loss must be supported by a medico-legal report prepared by an ENT Surgeon or Consultant Otolaryngologist.

Regulatory framework
In the same way, the ‘Code of Practice’ superseded the guidelines of the ‘Noise & The Worker’ Booklet, the formal ratification and subsequent issue of the ‘Noise at Work Regulations, 1989’, effectively replaced the ’72 Code.

Noise at work regulations
The ‘Noise at Work Regulations, 1989’ were laid before Parliament in October 1989, taking effect from 1 January 1990.

Date of knowledge
Justice Mustill in the case of thompson –v- smith’s ship repairers (1984), queen’s bench division.

Breach of duty
The so called conventional position for occupational noise exposure prior to 1 January 1990 is that a claimant must establish that he was exposed to levels of noise at or in excess of 90dB(A) leq time weighted over an 8 hour day.

Limitation
The reader is referred in the first instance to the general section on limitation which touches in general terms upon limitation issues involving noise induced hearing loss claims.

Quantum
The assessment of general damages for noise induced hearing loss cases.

Apportionment and contributions
Deafness is generally recognised to be a divisible disease/condition and the principals laid down in the Court of Appeal’s decision in holtby -v- brigham & cowan limited will ordinarily apply.
