Building silence into a UI design is just as important as knowing when to apply sound. In many instances, sound isn’t needed and it can actually detract from user focus and comfort. Similar to using negative space in visual design, silence creates a space for other elements to receive focus.

For example, sound isn’t usually suitable for:

• UIs that require privacy or discretion
• Users who have requested no interruptions
• Actions that are performed frequently

In any context, sound should elevate the visual experience rather than detract from it.
