Title: The effect of transducer directivity on properties of time reversal focusing
Abstract: This presentation explores the effect of transducer directivity on the focusing properties of time reversal acoustics. Time reversal is a signal processing technique that can be used to focus sound to a location in space for source reconstruction, communication, and intentional sound focusing. One loudspeaker and one microphone are used to produce a time reversal focus in a reverberation chamber. The primary axis of the loudspeaker is oriented in various different directions to produce a time reversal focus for each orientation. Since source directivity depends on the frequency of the sound emitted, these experiments are conducted for a low frequency band and a high frequency band such that these two frequency bands have fairly different directivities. Properties of these foci are compared to determine the overall effect of directivity on the time reversal focus.
