Make sure that any background audio is not distracting, or can be controlled.
What can I do?
If your videos have background audio, i.e. they have speech in the foreground and a background track, make sure that:
- Either the learner can control the background sound, i.e. turn it off.
- Or the background sound is low, ideally 20 decibels lower than the foreground speech.
Better still, do not have background audio.
- Background audio can be distracting for all learners.
- People who have a hearing impairment, often have great difficulty separating speech from background sound.
The following video clip demonstrates how background audio can make it difficult for your learners to hear the audio narration in the foreground.
