This test only detects the most common type of hearing loss. The sound response of computers, speakers and headphones varies and can effect this test.

To run this test:

1. Make sure the room is quiet.
2. Push the "Set Level" button and a sound will play for 10 seconds. Adjust your speaker or headphone volume until you can just barely hear the sound (headphones preferred). If using headphones, test one ear at a time.
3. Push the 500, 1000, 2000, 4000 and 8000 Hz buttons without re-adjusting anything. Skip the 500 Hz tone unless your environment is really quiet.
4. If you are not able to hear one of these tones you may have a hearing problem.
5. Try increasing the sound level of the tones you didn't hear to verify the tone was playing on your device.
6. Have another person check the tones you are not hearing to see if they can hear them.
