title: Fitting Strategies for Multiple-Memory Programmable Hearing Instruments.
abstract: Fitting a multiple-memory programmable hearing instrument presents a new set of challenges to the dispenser, compared to conventional fittings. Rather than having to compromise on a single frequency-gain response (the prescriptive target), it is now possible to create a family of hearing aid responses from which the user can select an appropriate response for a given situation. This philosophy is also applicable in the prescription of compression characteristics. The flexibility designed into the 3M two-channel compression system allows the dispenser to program very different types of signal processing strategies (low frequency compression, high frequency compression, full spectrum compression, or linear processing) into a single instrument to match the requirements of different listening environments and to meet the needs of different users. Utilizing this approach, comfort, speech intelligibility, and sound quality can be optimized in a variety of situations by considering the listener's acoustic environment and the input signals to which the hearing aid must respond.
