Abstract: A hearing test system includes a sound generating unit, an user interface, and a control unit. The sound generating unit is configured to generate a first testing sound at a frequency for a subject. The user interface is configured to receive a first feedback of the subject based on the first testing sound. The control unit is configured to determine whether the first feedback is of heard response or an unheard response. When the control unit confirms that the first feedback is of the heard response, the control unit drives the sound generating unit to generate a second testing sound based on a lower testing limit at the frequency, in which a volume of the second testing sound is less than or substantially equal to a volume of the first testing sound.

The neckband defines a virtual datum plane and a first virtual plane parallel to each other, wherein the virtual datum plane overlaps a coronal plane of the user when the neckband is worn by the user, and a skin portion, furthest from the virtual datum plane, of a throat of the user is located on the first virtual plane. The first virtual plane is distant from the virtual datum plane by the first distance. The first microphone is disposed on the neckband, and is distant from the virtual datum plane by the second distance, wherein the second distance is less than the first distance.
