An electronic device may include one or more microphones that monitor ambient noise and generate ambient noise data. The electronic device may include processing circuitry that receives the ambient noise data and compares the ambient noise data to a baseline ambient noise profile to detect changes in the ambient noise. Changes in the ambient noise may be caused by user gestures. The electronic device may compare the changes in the ambient noise to characteristic changes in ambient noise that are associated with user gestures to determine the user gesture made by a user. The processing circuitry may modify the operation of the electronic device based on the user gesture. An ambient noise input device may include surface features or movable components that cause the characteristic changes in the ambient noise. Ambient noise input devices may provide feedback to guide a user to provide input using ambient noise sensing.
