BENTHOWAVE INSTRUMENT INC. Acoustic Transducer & System
Automatic Sensitivity Control Hydrophones (receivers) detect the information being carried on
by signal frequencies, and not by signal levels (amplitudes) and
phases such as Doppler sonar for speed
measurement, ASK and FSK digital communication, etc...
The hydrophone maintains suitable (or constant) voltage
amplitude at output despite the variations of the detected sound
pressures by automatically reducing its sensitivity when the sound is strong and raising it
when sound is weak. It has 80dB dynamic range
to equalize the differences in received sound intensities emitted by
different sound sources, amplitude variations in a single sound source due to
fading or reduced power, as well as varying echo levels caused by
sound propagation loss in SONAR and ultrasonic testing.
The built-in bandpass filter allows the receiver to detect the sound
of the interest and reject the sounds out of its bandwidth.
