Selecting a hearing profile for sound enhancement
The hearing profiles alter the sound of the audio signal in order to
especially improve the speech intelligibility. The profiles are used to
specifically change certain frequency ranges by e.g. boosting or
attenuating low-frequency or high-frequency tones.
All three hearing profiles feature a compression function which
compensates for volume differences by boosting the volume of
quiet passages and reducing the volume of loud passages if necessary.
The balance setting is saved on the receiver. If you are using
several receivers with a transmitter, the respective receivers
are optimally adjusted to match the personal hearing preferences of the users (e.g. you and your partner). Please note
that the personal hearing preferences can only be adjusted
when only receiver is connected to the transmitter.
