1866 results about "Acoustic board" patented technology

An acoustic board is a special kind of board made of sound absorbing materials. Its job is to provide sound insulation. Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, when sound passes through an acoustic board, the intensity of sound is decreased. The loss of sound energy is balanced by producing heat energy.

Gas film structure capable of effectively reducing sound focusing in gas film

The utility model belongs to the technical field of gas film buildings, and particularly relates to a gas film structure capable of effectively reducing sound focusing in a gas film, which comprises a gas film, a steel wire rope, a sound-absorbing plate and a reinforcing rope, a plurality of hanging rings are arranged at the top of the gas film, one end of the steel wire rope is connected with the hanging rings in a hanging manner, and the other end of the steel wire rope is connected with the sound-absorbing plate in a hanging manner. The adjacent sound absorption plates are arranged in an up-down staggered mode, and the reinforcing rope is connected with a plurality of steel wire ropes in a tying and hanging mode. The plurality of sound-absorbing plates which are arranged in an up-down staggered manner can enable part of sound waves reflected by the upper sound-absorbing plate to be reflected by the lower sound-absorbing plate again, so that the sound waves are absorbed for multiple times, and the sound attenuation effect is effectively improved; a plurality of steel wire ropes can be connected into a whole through the reinforcing ropes, and the hanging stability of the acoustic board is improved.
