摘要:
The present invention relates to a novel sound attenuating system. More particularly, the invention relates to a simpler, lighter, and more effective noise attenuating laminate which is made up of five specific layers of material. The laminate includes a duct liner, a moisture barrier, a fire barrier, acoustic attenuating material, and a solid backing sheet. The laminate is readily inserted into various sections of a jet engine compartment in order to attenuate the sound produced by the jet engine. Hollow rivets are used to conduct acoustical energy to the noise attenuating laminate. This novel means for conducting the acoustical energy to the laminate of the jet engine compartment allows for an improved anti-icing system, for more efficient jet engine operation, and for more efficient dissipation of acoustic energy.
