Fig. 12.2: The human hearing range | The human ear can normally only hear frequencies from 16 to 20000 Hz. Higher frequencies are described as supersonic, lower ones as infrasonic. The perceptible sound pressure is between 10 - 5 Pa and 100 Pa, whereby a sound pressure of 100 Pa nearly always leads to the immediate loss of hearing in humans.
The human sense of hearing does not perceive the various sound pressures and frequencies with the same intensity. The audibility range offers a summary of the sound pressure and frequency ranges perceptible to humans. The bottom limit of the curve shows the audibility threshold and top curve the pain threshold. The largest range of sound pressure perceptible to the human ear is at around 1 000 Hz. |
