What do the UDL Guidelines suggest?
1.2 Options that provide alternatives for auditory information
Sound is a particularly effective way to convey the impact or "energetics" of information, which is why sound design is so important in movies and why the human voice is particularly effective for conveying emotion and significance. However, information conveyed solely through sound is not equally accessible to all students and is especially inaccessible for students with hearing disabilities, for students who need more time to process information, or for students who have memory difficulties. To ensure that all students have equivalent access to learning, options should be available for any information, including emphasis, presented aurally.
