Applies to all technologies except those for voice interaction.
This technique relates to Success Criterion 1.4.2: Audio Control (Failure).
This describes a failure condition for Success Criteria involving sound. If sound does not turn off automatically within 3 seconds and there is no way to turn the sound off then Success Criterion 1.4.2 would not be met. Sounds that play over 3 seconds when there is no mechanism to turn off the sound included in the content would fall within this failure condition.
- A site that plays continuous background music
- A site with a narrator that lasts more than 3 seconds before stopping, and there is no mechanism to stop it.
- Check that there is a way in a Web page to turn off any sound that plays automatically for more than three seconds.
- If step #1 is not true then content fails Success Criterion 1.4.2
