Abstract
A human hearing test method relates to the following procedures: a musical note from a pre-recorded music in a storage device is loaded by a controller; a next test sound is then selected and played randomly from one of the pre-designed octaves and test frequency bands by using a random number and the musical note loaded by the controller; the sound level of the next test sound is then increasing or decreasing determined by a testing subject's last response to the last test sound and its sound level loaded by the controller from the data recorded earlier in the storage device; a next test sound is determined by the corresponding sound octave number and the musical note loaded by the controller from the storage device, and by the sound level of the test sound.
