The use of silicone membranes in aviation. In modern aircraft, structural panels are often used extensively in the cabin and wings, although they help reduce
weight while maintaining strength, but there is no doubt that during the flight will create serious noise. To that end, scientists from North Carolina State
University and the Massachusetts Institute of Technology have successfully developed new thin films that help silence the panels. The film is made of rubber
and is only a quarter of a millimeter thick, allowing it to adhere tightly to the edges of the panels. During flight, the film acts like the drum face of a drum and
bounces back the vibrations of the incoming sound. According to the actual test, the film can effectively resist the low frequency sound produced by the aircraft
engine and so on, can block 100 to 1000 times the sound vibration in the laboratory test.
