How to design the formula of underwater sound-absorbing rubber?

Hydroacoustic sound-absorbing rubber is used on the non-emitting surface of the inner wall of the ship's sonar dome to eliminate sound reflection and noise; used on propellers to reduce noise; used on submarines and mines to counteract enemy sonar detection. The reason why underwater sound-absorbing rubber can be used as a sound-absorbing material is that it meets two requirements: first, the characteristic acoustic impedance of rubber matches the acoustic impedance of the sound wave propagation medium (water); second, the rubber must have high damping. When sound energy enters the material layer, the energy attenuation is extremely high, ensuring that all sound energy is absorbed in the material layer. The elasticity of rubber is the main reason why rubber is used as an underwater sound-absorbing material. When sound waves act on the rubber material, the rubber material deforms, and the relaxation process of the rubber molecular chain causes a hysteresis effect in which the strain lags behind the stress, resulting in energy loss. Butyl rubber and nitrile rubber have high internal friction, so they are suitable for sound-absorbing rubber. Natural rubber and styrene-butadiene rubber have the lowest internal friction, and chloroprene rubber is among them. Butyl rubber is commonly used to make hydroacoustic rubber because of its high internal friction, excellent water resistance and aging resistance, and is suitable for long-term use underwater
