Active Noise Curtain by Waves
« on: February 03, 2006, 06:52:37 PM »
Once I have seen a ANC system in Turkey brought from USA , which was isolating a huge theatre music sound without any seen curtain but may be microwaves. Any step you get through the electronic curtain there was a huge sound of a pop concert, but when one step back , there were no sound. Imagine the system was outputting more than 20.000watts. Is there any one who knows, which company manufactures susch a system , or any web sites, or any information about such a technology?
