There are nine million deaf and hard of hearing people in the UK – a seventh of the population.
This number is increasing as the number of people over 60 rises.
While noise levels at work are better regulated now than in the past, people still lose their hearing as a result of their occupation.
Those working in the entertainment and leisure industries, including DJs, bar staff, broadcasters and fitness instructors, are among those at risk.
Being hard of hearing can cause people to withdraw from social interaction and lose their confidence, their independence and their sense of security.
The safe level of noise is 85 decibels, which is equivalent to being in a normal office environment.
The NHS does provide hearing aids but there is a two-year waiting list.
