A programmable apparatus improves perception of sound by a person. The ap paratus includes a processor, digital-to-analog converter, audio output sect ion and means for generating first and second control signals. The processor executes one or more available programs for processing digital audio signal s based on control signals. The digital-to-analog converter generates output analog audio signals based on the digital audio signals. The audio output s ection receives and amplifies the output analog audio signals, generates aud ible sound based thereon and provides the audible sound to the person. The m emory stores programs for processing the digital audio signals. Based on an action by the person, a first control signal is generated which causes the p rocessor to switch from one available program to another available program s o that the person may cycle through and evaluate each of the available progr ams. Also based on an action by the person, a second control signal is gener ated which causes the processor to designate at least one of the available p rograms as a chosen program for continued use. The apparatus may include a c ounter that counts the number of times that power is applied to or removed f rom the apparatus. After a predetermined elapsed time, the processor determi nes which of the available programs has been used most in processing the dig ital audio signals, where the determination of elapsed time is based at leas t in part on the counter value.
