Volume Control

ISSUE:

The ability to hear or distinguish sounds may be difficult or impossible for some users. Individuals who are deaf or hard-of-hearing and users who work in noisy environments may require a high level of audio output. Conversely, screen-reader users may wish to decrease the volume for application sounds, so they will not conflict with synthesized speech output. An option should be available that allows the user to adjust the volume for audio output.

STANDARD:

• Applications should provide a volume control option for audio output.



• Applications should respect system volume settings.

Programmer's Note: Windows applications that play sounds by calling PlaySound and specifying a registry-based sound event do not require additional work to be accessible. Users can adjust or disable these sounds using system volume controls.
