We talk about hearing loss when we perceive a difference between the minimum sound level perceived normally (also called normal hearing threshold) and the level perceived by the affected individual.

These levels are calculated in decibels (dB) knowing that we are talking about normal hearing when the average loss is between 0 and 20 dB.

We can distinguish 4 degrees of disabilities :

– the mild hearing loss : with a loss of between 20 and 40 dB.

– hearing impairment medium : with a loss of between 40 and 70dB.

– hearing impairment-severe : with a loss of between 70 and 90 dB.

– the profound loss : with a loss is greater than 90dB.
