Abstract
Suppression of tapping noise caused by tapping an acoustically coupled touchscreen. When a tapping event is detected on the touchscreen, a tapping noise suppressor is alerted of the event, and responds by at least temporarily mitigating the tapping noise in the audio stream. The suppression occurs temporarily for at least part of the duration of surge in audio levels that occurs as a result of the tapping event, and in a manner that reduces the psychoacoustic impact on the conversation. Suppression may be performed by first placing the tapping noise suppressors in an alert mode when a tapping event occurs. The tapping noise suppressor then monitors the audio stream generated by the microphone for the beginning of the tapping event—which will be represented in the form of a surge in volume. The tapping noise suppressor then temporarily applies the suppression window.
