Which type of sound should you use when?

Behavioral intent —

Behavioral intent in sound design goes beyond mere notification. Our approach actively conveys the action your user should take through the shape and tone of the sounds we design for you. It also considers the emotional impact of sounds, critical for people with cognitive and sensory disabilities. This ensures clear guidance and support across all disabilities.

1. Guidance . Streamline your signup, onboarding, and account set.

Behavioral intent: Alleviate confusion and frustration. Guide users through tasks with clear instructions. Signify task completion so people know when to move to the next step.
Characteristics: Voice prompts should sound warm and friendly, with a clear and conversational tone. Successful completion should be indicated with a forward motion sound.

2. Alerts . Accessible marketing communication.

Behavioral Intent: Ensure important alerts, like trigger warnings, capture attention without causing panic or anxiety.
When cautioning, use a gentle yet firm tone. The shape of the melody or sound design should infer a question to prompt a decision.
"Are you sure"

3. Confirmations . Security and peace of mind

Behavioral Intent: Provide assurance and confirmation of successful actions or critical decisions to reinforce trust and confidence.
Characteristics: Use reassuring, and positive tones to convey completion, reliability and success.
