A touch input detector is disclosed. The touch input detector includes an acoustic transmitter for transmitting an acoustic wave across a touch input medium. The touch input detector also includes an acoustic receiver for receiving the transmitted acoustic wave, wherein the timing of the incidence of the acoustic wave on the acoustic receiver indicates at least a portion of a touch input location on a surface of the touch input medium. The touch input detector further includes an acoustic dampening material coupled to the touch input medium to dampen reflections of the transmitted acoustic wave.
