Estimation of Hearing Loss Using Interactive Pure Tone Audiometric Test with Embedded System Interface

Abstract

Hearing loss is a commonly occurred problem that develops with aging or caused by repeated exposure to loud sound levels. Hearing loss occurs as a result of sound signal not reaching to the brain. Audiometry is the process of measurement of hearing ability by which an audiologist performs hearing test to a person using a device called audiometer. In this process, hearing level is measured by passing audio signals from lower frequencies to higher frequencies through ear phones. The patient gives response to the heard sound pitches whether it is audible or not. The method we propose implements an automatic audiometric signal generation using an audio signal generator which is controlled by a microcontroller. The patient can give the feedback response using a ‘Yes’ or ‘No’ switches thought which the system process the collected data and compares with the played frequencies and calculate the hearing ability which can be displayed during the end of the testing process.
