On a high-speed hearing measurement compen-sated for gain for each sub-band

Abstract

Hearing loss is an inevitable problem for hu-mans. It gradually deteriorates with age. Excessive expo-sure to noise can cause further deterioration. Because hearing cannot be recovered once damaged, it is important to prevent and slow down the hearing loss. This requires a timely understanding of hearing loss and relevant protec-tive measures. This research proposes a sub-band method that can High-Speed measure hearing damage by itself. This method can be extended to the home without going to the hospital. In this method, by listening to 9 pure tones in sequence, you can detect your hearing impairment at high speed. The frequency gain compensation method is used to define each frequency band's reference critical value, and the cross-band test is used to determine the hearing loss part. The results showed that 1 out of 12 subjects was de-termined to be suspected of partial hearing loss. It has been confirmed that this experimental method can be judged within 30 seconds with a smartphone, compared to the detection method in the hospital. The detection speed has been greatly improved. It allows more people to learn about their hearing health easily. © 2020 Seventh Sense Research Group®.
