These elements, called projectors, are devices that produce the active sound pulse, or ping.
To simulate a string being plucked, Chafe and his team repeatedly sent a short sound pulse across a connection.
As range shortened, so did the time taken for the sound pulse to reach, and then return from, the target.
By firing each disc in sequence, the amplitude of the sound pulse increases along the length of the tube until it reaches the exit nozzle.
The test is carried out by generating an acoustic pulse from a speaker or spark source and this sound pulse is transmitted to the nose along a tube.
The pulse soon reaches the second disc, which is " fired " at precisely the right time so that the sound pulse it produces magnifies the pressure wave.
Sending an electrical signal to the first disc at the rear end of the tube makes it expand, sending a pressure wave _ a sound pulse _ along the tube.
This sound pulse is reflected back to a microphone and this reflection is generated according to the changes in the local acoustic impedance related to cross-sectional area of the nasal cavity.
:* Measurement of Doppler Shift : Some ships are equipped with sonar instruments that can measure the Doppler shift in a sound pulse generated by the ship's motion as it reflects off the ocean bottom.
