ABSTRACT:
A digital signal processing hearing aid is disclosed having a plurality of digital signal processing means for processing input digital signals, and a selector switch manipulable by a user for choosing which of the processing means to utilize. Each of the digital signal processing means is designed to provide optimal results in a particular listening environment. Since the user is allowed to choose which of the plurality of processing means to invoke, and since each processing means is specifically designed to operate in a particular listening environment, the hearing aid is capable of providing excellent results in a plurality of listening environments.
