1. A hearing system including a fitting equipment and a hearing aid, the fitting equipment comprising a computer having a
display, where the computer is provided with a fitting software adapted for controlling parameters of the hearing aid upon
control of indicators in the software, where the indicators are visible on the display, where a control with three alternative
settings are selectable to change the manner in which the gain, amount of compression, and compression type are implemented
in the fitting, in that a default fitting rationale is selectable and may be chosen and where further, in the fitting software,
at least two variant settings which are offset in relation to the default setting are selectable provided and may be activated
from the software by means of the computer, wherein:
the default fitting combines fast acting compression in the LF channel with slow acting Adaptive Gain in the HF channel,
the first variant setting combines lengthening of the release time in both the LF and HF channels with reduction of the amount
of gain for soft inputs in both the LF and HF channel, and
the second variant setting combines shortening of the release time in the HF channel with increase of soft gain in both the
LF and HF channels.
