What Is Auditory Stimulation?

A suitable stimulus for hearing is a sound wave emitted by the vibration of an object. Under the most suitable conditions, the human ear can hear sounds in the frequency range of about 20 to 20000 Hz. Sounds in this frequency range are often called audible sounds. In speech analysis and hearing tests, the frequency range of 125 ~ 8000Hz is most commonly used. The degree of hearing loss is generally measured by the average hearing loss of pure tones at three frequencies of 500, 1000, and 2000 Hz, because these three frequencies are areas where speech frequencies are relatively concentrated.
