    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.

    摘要翻译： 本发明涉及一种新型的声音衰减系统。 更具体地说，本发明涉及一种由五个特定材料层组成的更简单，更轻和更有效的噪声衰减层压板。 层压板包括管道衬垫，防潮层，防火屏障，声衰减材料和固体背衬片材。 层压板容易地插入到喷气发动机室的各个部分中，以便减弱由喷气发动机产生的声音。 空心铆钉用于对噪音衰减层压板进行声能。 这种用于对喷气发动机舱的层压板进行声能的新颖手段允许改进的防冰系统，用于更有效的喷气发动机操作，以及更有效地消散声能。

    摘要： The present invention relates to a novel sound attenuating laminate. More particularly, the invention relates to a simpler, lighter, and more effective noise attenuating laminate which is made up of seven layers of material. The laminate includes a duct liner, a moisture barrier, a first protecting layer, a screen, acoustic attenuating material, a second protecting layer, and a solid backing sheet. The laminate is readily incorporated 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 intermediary layers of the noise attenuating laminate.
