Age Test is a fun gadget to find if you can hear different frequency of sounds. This sound is so called Mosquito Sound, which gives off high-frequency noise. In humans the maximum range of audible frequencies normally lies between 16 Hz and 16,384 Hz (16.384 kHz); not to be confused with the common sound system speaker range of 20 Hz to 20 kHz (Hz is the standardised term for cycles per second), although there is considerable variation between individuals, especially at the high frequency end, where a gradual decline with age is considered normal.

Do you or someone you know think you have a hearing loss? Often times it is difficult to tell because hearing loss usually occurs gradually such that the person is not aware of it. Results obtained using the tone test are not a substitute for a valid hearing test under the supervision of a trained professional in a controlled environment.
