Paper Abstract

Acoustic power amplifiers have low efficiency. It can amount to 60 - 70% in ideal conditions. Due to this efficiency, high power amplifiers weigh a lot and are large in size. Improvement of the efficiency of an acoustic amplifier can be achieved through supplying a given amplifier with a voltage that is proportional to the input signal. Our paper describes how to increase the efficiency.
