Hearing loss is one of the most common causes of disability in the world today,affecting about one-sixth of the world's population,20％of which is caused by noise exposure.Young people with normal hearing can hear tones at 20 Hz～20 kHz.Currently,conventional pure tone audiometry(125 Hz～8 kHz)is widely used in clinical prac-tice,and extended high-frequency audiometry(EHFA)(9 kHz～20 kHz)is not readily available in clinical services.There is growing evidence that extended high frequency audiometry can provide information on early hearing condi-tions such as latent hearing loss and decreased speech recognition,as well as senile hearing loss,with better sensitivity than that of conventional audiometry and otoacoustic emission testing.This paper discusses the progress of research on EHFA in noise-induced hearing loss.
