AUTOMATIC SYSTEM FOR OPTIMIZING HEARING AID ADJUSTMENTS

摘要

A system for optimizing hearing aid adjustments is disclosed. The system includes a computer (10). Speech material consisting of nonsense sentences or unrelated words from a word list is provided (12). The words are rich in frequency content and replete with time and amplitude variations. The speech material is presented aurally by a computer system (10) to a hearing impaired individual wearing an electronically adjustable hearing aid (14). The individual repeats the words, and the computer system (10) compares the repeated words to the original speech material and identifies the incorrect words in an error file. The system considers the incorrectly identified words and uses pre-knowledge of their frequency content and their time and amplitude variations to calculate an imputed inverse transform for a digital (DSP) aid.
