Abstract:
A hearing aid, comprising:an input transducer for converting sound into an input signal; a signal processing circuit for filtering and amplifying the input signal in accordance with a set of specified signal processing parameters to thereby produce an output signal; an output transducer for converting the output signal into sound; a timer; a programmable controller for specifying processing parameters to the signal processing circuit; wherein the controller is programmed to select a signal processing parameter set for specifying to the signal processing circuit from a group of such parameter sets and sequence through the group of parameter sets from an initial parameter set to a final parameter set; wherein the controller is programmed to sequence through the group of parameter sets in accordance with elapsed operating time intervals and to select a next parameter set from the group of parameter sets after an operating time interval specified for each parameter set; and, wherein the sequence of parameter sets represent gradual hearing compensation at increasingly optimal levels until the final signal processing parameter set is reached which represents optimal hearing compensation.
