Set computer volume level at normal. Using headphones or your speakers, play each tone, gradually decreasing the volume until you cannot detect it. Note the volume setting (I know, this isn't easy if you don't have a graduated control, but you can make some arbitrary levels using whatever indicator you have on your OS).
Repeat with next tone. Try the test with headphones if you were using your speakers, or vice versa.
