Gain is the ratio of output amplitude to input amplitude of a booster or a horn. When the gain is greater than one, the output amplification is larger than the input amplitude.

Gain is utilized as a way to increase or decrease the amplitude of an ultrasonic system. Each plastic and each application have different amplitude requirements and thus different combinations of boosters and horns are required to achieve the appropriate gain.
