piezoelectric transducer (PZT). The relationship between source impedance and sound pressure level is measured, single-ended (S/E) and bridge-tied load (BTL) driving schemes are compared and the input impedance of a PZT is characterized. Audible piezoelectric transducers (PZTs) are often used as warning devices or alarms. Manufacturers of piezo transducers publish

https://www.cuidevices.com/blog/how-to-increase-the-audio-output-of-a-piezoelectric-transducer-buzzer
In most applications the reason for utilizing a piezoelectric transducer buzzer is to create a loud sound, where the amplitude of the sound produced by a buzzer is dependent upon both the specific buzzer selected and the signal used to drive the buzzer. There are several ways to affect the audio output of a piezo buzzer based upon the design of the driver circuit.
