01. Principle

In UX design, sound is a means of delivering key information that can be used to assist visual information.
You can use sounds to support visual experiences when describing the system or app’s state or giving feedback on user interactions. Sometimes, you may also use sounds to deliver information more effectively when there is a lack of visual information available.

Sound design principles

1Use sound consistently
Sound feedback should be used consistently and appropriately. Unexpected sounds may confuse the user, making them feel as though the system is hard to understand or unpredictable.

2Provide positive sound feedback
Provide positive sound feedback when a goal is accomplished or a task is completed. This will ensure a better user experience and also help the user better remember its meaning.

3Avoid using repetitive sounds
It’s possible that the user may find auditory stimuli rather annoying than visual stimuli.Don’t use sounds excessively or force the user to hear the same sounds repeatedly, no matter how pleasant the sounds are.
For example, when the user uploads a photo, it’s better to give sound feedback only once after the photo is uploaded, rather than giving sound feedback repeatedly while the photo is being uploaded.
