AI summary

A programmable apparatus improves perception of sound by a person. The apparatus includes a processor, digital-to-analog converter, audio output section and means for generating first and second control signals. The processor executes one or more available programs for processing digital audio signals based on control signals. The digital-to-analog converter generates output analog audio signals based on the digital audio signals. The audio output section receives and amplifies the output analog audio signals, generates audible sound based thereon and provides the audible sound to the person. The memory stores programs for processing the digital audio signals. Based on an action by the person, a first control signal is generated which causes the processor to switch from one available program to another available program so that the person may cycle through and evaluate each of the available programs. Also based on an action by the person, a second control signal is generated which causes the processor to designate at least one of the available programs as a chosen program for continued use. The apparatus may include a counter that counts the number of times that power is applied to or removed from the apparatus. After a predetermined elapsed time, the processor determines which of the available programs has been used most in processing the digital audio signals, where the determination of elapsed time is based at least in part on the counter value.
