A double acoustic resonator is a device which can cut down two resonance peaks of an acoustic cavity excited by sound sources in the ‘low frequency’ range. A straightforward design method is proposed; with this method a double resonator is designed in order to cut down two resonance peaks of an experimental cavity. Then the extensive series of test which was performed to assess double resonator performance is described and the sensitivity of the system to resonator tuning errors is discussed.

Abstract
A double acoustic resonator is a device which can cut down two resonance peaks of an acoustic cavity excited by sound sources in the ‘low frequency’ range. A straightforward design method is proposed; with this method a double resonator is designed in order to cut down two resonance peaks of an experimental cavity. Then the extensive series of test which was performed to assess double resonator performance is described and the sensitivity of the system to resonator tuning errors is discussed.
