Part 3 sounds the same as Part 2. It
starts as a low-pitched sound from
your speaker. The sound's pitch
increases smoothly until it reaches a
peak, stays steady for a second and
then diminishes until the sound is
gone. After this part of the Sound
Test is complete, a third speaker with
a flashing "9" underneath it appears
on the screen.
