Hero sounds are representations of a product and brand that highlight an important moment, evoke an emotional state, or express celebration.

They occur in pivotal interactions, such as those that:

- Celebrate a significant positive action the user has taken
- Welcome users to a new app or experience
- Confirm a key moment of a product’s purpose

Hero sounds occur infrequently, and because of their prominence, they should be applied in consistent ways.

Sound use cases

Hero sounds

Notifications are prominent requests for user attention. Their primary role is to help direct user attention, and they provide an opportunity to give a custom sound identity to emphasized interactions. Because they occur more frequently in a UI than other sounds, they should generally be shorter than hero sounds and crafted in a way that is suitable for being played multiple times.
