Self-service Hearing Estimation Software Using Computer Sound Card

Abstract

The implementation of pure tone threshold hearing estimation method into self-service screening software is described in this paper. The purpose of software is to determine the hearing threshold by a graph of the lowest signal intensity as a function of signal frequency which can the person under test hear during certain measurement conditions. The proposed solution can be integrated for use in mobile system for screening and monitoring as well as used for self-screening in household use. The results of hearing test can be stored in data base for each individual and used for further analysis in order to determine the presence of hearing disorders. Proposed software implements flexible use of sound recording and playback features through computer peripherals, more important, calibration and noise measurement is used in this software to obtain reliable results.
