A DSP-Based Solution to the Early Identification of Hearing Impairment

Abstract

This paper describes the development of a low cost DSP solution for the early identification of hearing impairment. The desire is to develop a cost-effective, highly sensitive, and easily administered screening system for the evaluation of human hearing acuity.

The proposed system is called EARTEST. EARTEST is basically a DSP-based screening audiometer capable of performing pure tone air conduction testing.
