Abstract

This relates to a sound-absorbing panel with a multiple elastic membrane provided with dampers which absorb vibrations. The membrane consists of two panels of sound- absorbing material with an interposed metal acoustic insulation sheet. The panel is particularly suitable for anti-noise barriers for roads, railways, rapid-transit systems, etc. <IMAGE>
