The device (D) has a layer (1) facing a sound source to be occulted and comprising a fabric occulting weight greater than 250 g per square m. Another layer (2) comprises metalized fabric that includes a metal layer (2a) placed in contact with the layers. A third layer (3) comprises scraped cotton fabric whose weight is greater than 250 g per square m, where the fabric is placed in contact with the latter layer opposed to the former layer. The fabric is formed by vacuum metallization of a previously calendared woven substrate by application of compressive force.
