IPC: G10K11/16
Filed: 1989-05-26
Abstract: PURPOSE:To obtain the high-performance sound insulating panel of a lightweight and thin type by providing fibrous materials which generate heat when conducted between front and rear plates. CONSTITUTION:The fibrous materials 1 which exhibit an exothermic effect when conducted are disposed as a phase control element and sound absorbing element for sound waves between the front and rear plates 2 and 3.

The sound waves are theoretically totally reflected when the difference increases to a certain incident angle or above and, therefore, the transmission energy is diminished and the sounds are insulated over the entire part of frequencies. The total reflecting phenomenon and sound absorbing effect of the sound waves are generated in this way, by which the high performance is obtd. with the light weight and the small thickness.
