Soundproofing With Miracle Holes
A Patented Technology (2013)
The soundproofing wall with high ventilation capability.
The traditional ways of soundproofing are cutting off the boundary by the sealed wall or door.
The new technology does not need the sealed plates and walls for the soundproofing. Additional electric energy and driving tools are also unnecessary to use this technology.
It can be applied to curtains and walls between rooms to reduce voice and sounds. As holes in the soundproofing wall make the air circulation free, the air-flow from the air-conditioner is not obstructed. Also, this structure enables drastic cost reduction to construct soundproofing walls which require high aerodynamic loading such as for highways and railways.
This is the patented technology.
