Audio Icon

A non-speech sound used in a user interface to represent an object, action, or event, analogous to how visual icons represent concepts graphically. Audio icons use everyday sounds that have a natural association with what they represent (e.g., a crumpling sound for deleting a file), while earcons use abstract musical tones with learned associations. In accessible application design, audio icons are used to create multimodal interfaces that combine visual and auditory representations, enabling interaction by both sighted users and users with visual impairments through the same interface elements.
