It might then paint a picture of what the sound bounced off of, like a college of fish. Frequencies range from infrasonic, which suggests very low, to ultrasonic, which implies very high.

Specifications. The EFF described here’s a differential amplifier designed to simply accept indicators from a submerged, grounded dipole electrode via a differential input. Amplification is managed by a 3 position change: off; low-achieve (x a hundred); and high-achieve (x 500). For either low or excessive-gain, the signal is further amplified (x 20) and converted into sound via an integrated loud speaker.
