<p>A panel (1) for the production of a sound-deadening conveyor duct (10) which can be incorporated in a conveyor system (20) for aeriform media, in particular for conditioned air, comprises a sound-deadening layer, inner surface (211), a support layer (3) of substantially rigid material connected uniformly to the outer surface (21) of the sound-deadening layer, and a filtering layer (5) which is formed of gas-permeable material and is connected uniformly to the inner surface (211) of the sound-deadening layer (2) and which is intended to delimit a conveying space (15) so as to allow sound waves to pass from the conveying space (15) into the sound-deadening layer (2) and to prevent impurities passing from the conveying space (15) into the sound-deadening layer (2) and from the sound-deadening layer (2) into the conveying space (15).</p> |
