Abstract

The invention relates to an acoustic insulation screen. The screen comprises a mat (5) constituted by a flexible envelope (4) inflated by a gas under pressure and permitting free circulation of the gas inside the envelope, this envelope being chosen so as not to transmit the vibrational energy from one point to another of the envelope and the gas being chosen from those gases in which the speed of sound is greater than the speed of sound in air. The invention applies especially to the protection of the compartment for the payload of a launcher.
