Propulsion by water jet, again one in each hull, gives a low acoustic signature.

By tying the received acoustic signature to the known type of programmed signal code, a specific fish is identified.

Measures were also taken to reduce electrical and acoustic signature.

The acoustic signature is made up of a number of individual elements.

For submarines, as a prime factor in how they can be detected the reduction of the acoustic signature is a primary goal.

These would have had a very low acoustic signature.

No special provision was made to minimise acoustic or pressure signature.

The bubbles, according to the Taylor statement, "have an acoustic signature and may produce a visible wake."

Its low magnetic and acoustic signatures reduces the possibility of setting off mines.

Each key on the keyboard makes a subtly different acoustic signature when struck.
