2019-06-26 Membrane absorbers, also known as panel and diaphragmatic absorbers, utilize the resonant properties of a membrane to absorb sound over a narrow frequency range.

In the low frequency range, the membrane-type resonator and the perforated panel constitute a two degrees-of-freedom (DOF)-resonant type sound absorption system, which generates two sound absorption peaks. Tuned Rubber Membrane Absorbers (Devices B and C) The specifically tuned low frequency absorbers, membrane type, are apparently not very successful in the performed evaluations. The room would theoretically suit itself perfectly to these types of absorbers, with modal eigentones at almost precisely 40Hz, 50Hz and 63Hz. Abstract.
