In one embodiment, a device for processing sound includes a means for acquiring an input sound signal; a means for amplifying the signal with gain under the control of a control module in accordance with a set of control parameters; a means for setting, storing, and adjusting at least two sets of control parameters suitable for a "good hearing day" when hearing is a maximum and a "bad hearing day" when hearing is at a minimum; one or more continuously variable means for interpolating and extrapolating a set of control parameters from the "good hearing day" and "bad hearing day" fittings; a means for setting the control module parameters to the interpolated or extrapolated set of control parameters; and a means of converting the amplified input sound to an acoustic output signal. The device allows a user with fluctuating hearing loss to easily adapt the fitting of the device to an arbitrary "bad hearing day" fitting, an arbitrary "good hearing day" fitting or any fitting in between. The apparatus may be implemented in dedicated hardware embodiment or by software running on a microprocessor.
