listening to all that loud music. It does this by trying to find your upper
frequency hearing threshold. To ensure you don't cheat, it does three
different tests and averages the results. Just run the program and follow the
Test 1 produces a tone whose frequency steadily increases. Hit a key when you
can no longer hear it.
Test 2 produces a tone you should not, initially, be able to hear. The
frequency steadily decreases, though, and you should hit a key as soon
as you can hear it.
Test 3 invites you to use the arrow keys to adjust the frequency of a tone
until that you can just hear it. Hit [Return] to complete the test.
