Membrane-type acoustic metamaterials (MAM) are composed of a thin, prestressed membrane with periodically attached masses. This design allows for a very thin and lightweight construction that, in combination with a back cavity, can achieve perfect sound absorption at subwavelength length scales. However, MAM-based sound absorbers achieve significant sound absorption values only in a narrow frequency band. This means that when tonal noise from sources with varying tonal frequencies (e.g. propeller engines) should be reduced using these absorbers, the noise reduction will be significantly impaired as soon as the tonal frequency of the source falls outside the sound absorption frequency band of the MAM. In this contribution, a preliminary investigation of an active MAM-based absorber with re-configurable sound absorption frequency bands will be presented. The proposed active MAM consists of a MAM with attached electrodynamic actuators and sensors, which could enable an in-situ modification of the MAM properties. An analytical model of the active MAM absorber will be used to study different sensor-actuator combinations that could be used to achieve the control of the sound absorption band over a wide frequency range.
