On a fast hearing test method according to sub-band listening frequency

Abstract

Modern man is exposed to an environment where hearing is susceptible. Hearing generally worsens in the higher frequencies as the body ages. However, in the case of noise-induced hearing loss, there is a possibility of partial hearing loss. The pure sound hearing test listens to the pure tone of each frequency for 250–8 kHz sound, which is used in everyday conversation, and grasps the response of the sound, but it takes a lot of time to measure the hearing. In this paper, we propose a new method for screening hearing in the sub-band area without being examined in the hospital. We extended the pure audio hearing measurement method by voice sub-band and examined the noise-induced hearing loss by band. The sound is divided into sub-bands, and the number of sounds heard is applied. The sound source heard at this time is nine pure tones with the frequency increased by Mel scale from 500 to 8000 Hz. If the number of sounds perceived in the sound source heard first is greater than the number of sounds perceived in the sound source heard later, the person with partial hearing loss is determined. In 12 trials, one of them was identified as suspected partial hearing impairment. By using this method, you can conveniently and easily determine whether you are hearing impaired to maintain a healthy life.
