An acoustic compressor is built using the acoustic resonator which shape was optimized for a maximum acoustic pressure amplitude and a low-cost compression driver. Acoustic compressor is built by installing a suction port in the resonator wall where the standing wave has its pressure node and a delivery port with a valve in the resonator wall where the standing wave has its pressure anti-node. Different reeds, serving as delivery valves, are tested and their performance is investigated. It was shown that the performance of such simple compressor is comparable, or better, than the acoustic compressors built previously by other researchers using non-optimally shaped resonators with more sophisticated driving mechanisms and valve arrangements.
