Abstract
A new method and apparatus for fluid sound amplification and detection having enclosed within a predetermined sized housing a fluid supply emitter in combination with a signal input port and spaced a predetermined distance therefrom along an axis offset a determined distance from the fluid supply emitter axis, at least one receiver, the receiver being responsive to gradient differences in fluid pressure as effected by laminar flow of the fluid from the emitter, a filter connected to the receiver for removing relatively high frequency noise, a diaphragm coupler receiving the output of the filter, the coupler having an output for use as a signal input to another predetermined sized housing, emitter, signal input port and at least one receiver combination. A suitable input transducer is connected to the signal input port of the first housing combination and a suitable output transducer such as a recording microphone and oscilloscope is connected to a receiver output of the second housing combination.
