The PB -2720 piezoelectric transducer is a super efficient electric to acoustic power converter. Note that a good output level is available across a wide frequency band but this peaks at about 4.5 kHz, at which point an output sound level of roughly 85 dB is obtained at a range of 10 cm from a 1V5 RMS input.
