Material Design Documentation

Principles of sound

"The sounds in a UI should work like a well-coordinated orchestra, both with each other and within the surrounding interface.

Three types of sound occur in a UI: 
- sound design
- music, and 
- voice. 

Each type communicates information and brand identity in different ways. Different types of sound can be used to create a particular effect, and multiple sounds can exist separately or together in the same UI.

While music and voice are part of a product’s soundscape, these guidelines focus on UX sound."
