The sound of silence

David Jones

Nature, 2000, vol. 407, issue 6802, 315-315

Abstract: Mobile phone users frequently annoy those around them by talking loudly into the phone. Daedalus has an idea for a phone that can be spoken into silently by using an ultrasonic signal to record the movements of the mouth and palate. Peace at last.
