What does hearing loss sound like?


To have a hearing loss can be a very challenging problem to have, and it can be difficult to describe to someone who has ‘normal’ hearing what everyday noises now sound like to a person experiencing a hearing problem.

To gain an understanding of what it is like to have a hearing loss, please use the simulator below to experience the affects of different degrees of hearing loss

The mild loss simulator is a reflection of the average hearing loss of a person aged 60. The severe loss demonstrates the amount of information a person with this type of hearing loss misses out on

The hearing loss simulation is based on two algorithms which simulate recruitment [1] and spectral smearing [2].
