3.7.13 OSPL90

The OSPL90 is defined as the maximum output level of the hearing aid measured at an input level of 90 dB.
This particular input level has been chosen as standard as it is enough to saturate the hearing aid in most
cases except if the volume control is set to an extremely low level.
The OSPL90 is often used when doing paediatric fittings in the coupler. This way you can ensure that the
output of the hearing aids never becomes uncomfortable for the child. It can, however, be recommended that
the hearing aid maximum is evaluated on all clients.
Below is an example:
