KeypointsThe screening criteria provided by the Health Service Executive (HSE) for noise induced hearing loss (NIHL) in Control of Noise at Work Regulations, 2005 differ from the medico‐legal criteria of NIHL. NIHL is underestimated by the HSE criteria, specially in people over 40 years of age.We provide an alternative method of screening in “Brewster‘s Rule”, aligned with the medico‐legal criteria, which helps to identify early NIHL giving us a chance to prevent further deterioration of hearing.The HSE criteria in the UK needs review to reduce NIHL.INTRODUCTIONThe damage caused to hearing by excessive noise is termed as noise‐induced hearing loss (NIHL). Occupational sources of noise have long been identified as a cause of NIHL. The assessment of noise‐induced hearing loss can be problematic, as there is an overlap with other causes of gradual deterioration of hearing—most importantly age‐related hearing loss (ARHL). The relationship between NIHL and ARHL is complex, as with increasing age, NIHL slows down while ARHL increases. In addition, there is enormous biological variability and individual susceptibility to the effects of noise, thus making the estimation of the exact amount of hearing loss as a result of noise exposure difficult. Other causes of hearing loss, for example middle
