Sound

Sounds in One UI help make interactions easier and more intuitive while also providing emotional stimulation.

Sound is used to convey necessary information and draw the user's attention when they're not looking at the screen. One UI sounds are designed considering the type and importance of information, the frequency and register of the sound, and the environment and situation where the sound will be heard. This minimizes auditory fatigue and gives users a positive perception of the sound experience.

To avoid irritating users, sounds should only be used when necessary.

Clear and immediate auditory feedback

Feedback sounds respond instantly to user actions and help reduce the burden of unintended actions and increase the level of trust with the device.

Keyboard input sounds are played quickly and repeatedly. Auditory fatigue is minimized by carefully considering the frequency and length of each sound. Users feel comfortable even when hearing keyboard sounds repeatedly.

One UI provides different sounds for general input and cancel/delete actions. This helps users avoid mistakes and type more accurately.

A harmoniously articulated hearing experience

Sounds in One UI blend in naturally with other UI elements, such as motions and haptics, to create an immersive experience.

The Bixby sound prompt is minimalist, intelligent, and lively. It's carefully timed to match the motion. It uses a clear sound range that is easy to hear, so the user knows when to start talking and when to stop.

We will continue to improve audio prompts and accessibility sounds in One UI to help users who are heavily dependent on hearing due to disabilities.

Sound identity

Sounds make it easier for users to recognize the device's brand identity and can have a lasting impact.

One UI sounds match the visual language of soft curves. The sine waveform is used to provide a soft and clean feel. Austere and deep tones express a sense of space and contribute to One UI's uniqueness.

A consistent style of sound is provided for notifications, charging, changing the sound mode, and battery warnings which help users recognize the product and brand.
