Abstract The acoustic properties of elastic porous metal rubber (MR) are investigated. A mathematical model of acoustic properties is presented. The dependencies between the noise reduction factor and MR properties are derived that allow the noise reducing structures (NRS) effective in a wide frequency range to be developed.
