Adjusting the sound
Many programs have the Macintosh make sounds when your
attention is required or when you’re giving a command or
attempting an action that the computer cannot recognize or
perform at that time.
There are two ways you can adjust the volume of the sounds that
your Macintosh plays: by using the buttons on the front of the
computer or by using the Sound control panel.

Audio Compact Discs and Audio Tracks on CD-ROM Discs”
