Here are some important considerations for adding sound into your design.


Where does sound go?

Sounds is an important interface tool for all applications, including Internet of Things, Home Automation, Wearables, Medical, Fire/Safety/Security, Point of Sales Terminals, Handheld Readers, Industrial Products

Look and Listen for: Buzzers, Beepers, Transducers, Indicators, Speakers, Microphones, Piezo, Sounders, Horns and Custom Audio Devices

They are found wherever there is a user interface: Controls: Buttons, Keypads, Control Panels, Displays, LEDs, Beacons Audible Feedback: Confirmation, Rejection or Warning Tones


Do I need sound?

How do you know if you need sound? Here are some signs:


Look and Listen. Ask yourself these questions about your product

Does your product provide audible user feedback or warnings?

Does it beep when you press buttons?

Does it offer confirmation, rejection or warning tones?

Does it play one tone, multiple tones, voice or music?

Consider the added value of added buzzers, beepers, transducers, indicators, speakers, microphones,

piezos or horns.
