Use of Sound
Do not use:
Jingles or tunes
Loud signals
Use tones consistently
Provide unique but similar tones for similar situations
Use no more than six different tones
Ensure that people can discriminate among them
Always use in conjunction with a visual indication
Sounds, sometimes called Earcons, are useful for alerting the user:
To minor and obvious mistakes
When something unexpected happens
Where visual attention is directed away from the screen and immediate attention is required
When a long process is finished
Provide signal frequencies between 500 and 1,000 Hz
Allow the user to adjust the volume or turn the sound off altogether
Test the sounds with users over extended trial periods
Use sounds sparingly because they:
Are annoying to many people, including other users and nonusers in the vicinity
Can easily be overused, increasing the possibility that they will be ignored
Are not reliable because:
Some people are hard of hearing
If they are not heard, they leave no permanent record of having occurred
The user can turn them off
