1.4.7 Low or No Background Audio

(Level AAA)

For prerecorded audio-only content that (1) contains primarily speech in the foreground, (2) is not an audio CAPTCHA or audio logo, and (3) is not vocalization intended to be primarily musical expression such as singing or rapping, at least one of the following is true:

No Background
The audio does not contain background sounds.
Turn Off
The background sounds can be turned off.
20 dB
The background sounds are at least 20 decibels lower than the foreground speech content, with the exception of occasional sounds that last for only one or two seconds.

NOTE Per the definition of "decibel," background sound that meets this requirement will be approximately four times quieter than the foreground speech content.

Applying SC 1.4.7 Low or No Background Audio to Non-Web Documents and Software

This applies directly as written, and as described in Intent from Understanding Success Criterion 1.4.7.

For WCAG2ICT consideration: This doesn't seem to require additional notes. Do you agree? Thumbs up if agree.
