The last omnibus report on noise in New Zealand workplaces was carried out in 1984 when 15,957 workers in high noise-risk areas showed 6,493 (40%) were actually exposed above the exposure standard of 85 dB(A) and of the 3,700 (23%) who had audiometric screening, 15% had evidence (a loss at 4 kHz of 35 dB hearing at age 25 or 50 or more at any age) of noise-induced hearing loss (NIHL).1 A recent review showed that the numbers of new claims incurring a cost to ACC in 2005-6 (5,580 cases) were approximately double the figure in 1995-1996 (2,823), and the costs of NIHL have been estimated as NZ$198.32 million since 1995.2 Despite knowledge of effective controls since the mid-80s, there is no evidence that the prevalence of the condition is decreasing.
