title: A compact infrasound and pressure waveform generator for use with small cavities.
abstract: The described apparatus is a small portable sound and pressure-step generator capable of producting pressure levels of over 150 dB into cavities of maximum volume 30 cm3. The form of the pressure waveform is an exact replica of the electrical input waveform independent of leakage and flexibility in the cavity. Complex sound waveforms can be easily produced with the aid of a function generator.
