Table 5: Noise Induced Hearing Loss (NIHL) predicted from ISO 1999 as a function of noise exposure level for 45 years (adapted from Lutman et al. 2008)
Extent of
hearing loss to be expected from a working lifetime of 45 years at daily
continuous noise levels of 80, 85, 90 and 95 dB(A).
| NIHL at 4 kHz in dB |
Daily noise level in dB(A) |
| 80 |
85 |
90 |
95 |
| The values are for hearing loss at 4 kHz, which is the frequency
predicted to give the greatest hearing loss. Values are given for the
median, and the 5th centile (value exceeded by 5% of the population). |
