The application of high temperature damping technology in aerospace industry is increasing day by day, and some applications are very successful. The problems related to the stability of large spacecraft and the problems related to engine vibration, noise control and aircraft cabin noise control are all the applications of high temperature damping technology.

In view of the fact that the vibration and noise inside the cockpit is too large under special circumstances, the acoustic environment inside the cockpit has been paid more and more attention by airlines and aircraft manufacturers. How to reduce the noise inside the cockpit and improve the comfort of the aircraft has become one of the hot issues in aircraft research.

The noise in the cabin mainly comes from the structure sound and the air sound. In the control of the noise in the cabin, the medium and high frequency air noise can be effectively isolated by laying sound insulation and absorption materials, such as heat insulation and sound insulation cotton, and improving the air tightness of the fuselage. However, the medium and low frequency noise caused by the vibration of the engine structure is less attenuated with the distance in the structure, which is difficult to be suppressed System. Especially for aircraft design, the weight and space are strictly controlled, and the medium and low frequency noise is always a problem in the control of aircraft cabin noise.
