Abstract
The concept of a sound reduction structure is proposed as a new method for reducing noises generated by vibrating solids. The proposed concept involves directly attaching hard sound absorbing materials to the vibrating surfaces of noise sources so as to provide a back air space. The effectiveness of the proposed concept is verified theoretically and experimentally using a one-dimensional acoustic field model. Then, the sound reduction characteristics in the three-dimensional acoustic field are clarified in detail through experiments using vibrating piston plates and a flexible flat plate with vibration modes.
