| Abstract: |
| The rubber materials had the characteristics of excellent damping performance，adjustable
acoustic impedance，easy formulation adjustment and simple processing，so it had a wide range of applications
in the underwater acoustic field. Based on the viscous absorption mechanism，thermal conduction absorption
mechanism and molecular relaxation absorption mechanism，it was concluded that the main approaches
to improve the sound-absorbing properties of the rubber materials were to design filler-filled or rubberblended
sound-absorbing materials. Moreover，the research progress of the sound-transmitting and soundreflecting
rubber materials was discussed based on the theoretical design and practical applications. Finally，
the challenges and future development directions of underwater acoustic rubber materials were pointed out. |
