A study on the self partial hearing test for voice sub-band

Abstract

Hearing ability does not recover once damaged. Therefore, in order to live a happy life, care must be taken to avoid hearing loss. Hearing loss due to the noise environment can cause partial hearing loss, in which the specific frequency band is damaged first. However, hearing loss is painless and difficult to detect at an early stage. In this study, we proposed a method to measure partial hearing loss by voice sub-band. As in Chapter 4, this method is used to discriminate partial hearing loss by listening to nine pure tones of different frequencies in the voice sub-band. As a result of Chapter 5, one out of twelve experiment participants was identified as suspected partial hearing loss. In addition, when the proposed participant described the proposed partial hearing test method, all the experiment participants discriminated themselves for partial hearing loss. These experiments confirmed that the proposed method is indeed a suitable method for partial hearing self test. © International Research Publication House.
