METHOD FOR ACOUSTIC REVERBERATION REMOVAL |
摘要 |
Disclosed herein are methods for canceling acoustic reverberations caused when acoustic energy impinges a medium. In one method, a series of positive pulses of acoustic energy are transmitted and the amplitudes of the resulting acoustic reverberations are measured. Negative pulses of acoustic energy are then transmitted having amplitudes equal to the immediately preceding received acoustic reverberation and at a time later than the positive pulses so that the acoustic reverberations are driven to a null. 86315ART0264 |
