OK gang, I just thought that I would share some pics from the process of building my new dedicated listening room, which is now completed.\r\n\r\n[IMG]http://img393.imageshack.us/img393/3551/dlr53gw7.jpg[/IMG]\r\n[IMG]http://img293.imageshack.us/img293/9182/p1020274ssf0.jpg[/IMG]\r\n\r\nIt took me one year and a half to complete, but it was well worth the wait. I simply love it.\r\n\r\nThe room size is 555 (L) x 430 (W) x 255 (H) cm.\r\n\r\nThe room was designed by a company that specialises in acoustic design. The room acoustics was was first designed in a digital domain and then improved upon with the real world measurements taken during all stages of construction work.\r\n\r\n[IMG]http://img87.imageshack.us/img87/4867/dlr9vw9.jpg[/IMG]\r\n\r\nThe room is soundproof and - among other things - features soundproof windows, double doors and 22cm thick double walls. The measured noise level inside the room is 26dB during the day (measured during rush hours, at 16:00), so it is almost dead quiet.\r\n\r\nI always dreamed about a dedicated listening room, but never had a chance to build one. The opportunity arouse when I bought a new appartment. In a true act of generosity, my wife let me take 2 out of 4 bedrooms for my future project (who needs 4 bedrooms anyway, when you have just one baby, right ? ;) ).\r\n\r\nThe appartment I bought was unfinished. \r\n\r\n[IMG]http://img140.imageshack.us/img140/4666/dlr1de9.jpg[/IMG]\r\n\r\nAs it quickly turned out, the existing walls needed to be razed to ground. Both my architect and acoustic engineer agreed that they need to be moved, although for a different reasons :-)\r\n\r\nAnother reason to dismantle them was insufficient soundproofing - and making the room sound proof was one of my highest priorities (my listening room is adjacent to my baby room, which in normal circumstances would preclude late night listening).\r\n\r\n[IMG]http://img388.imageshack.us/img388/4940/dlr2vo5.jpg[/IMG]\r\n\r\nWe decided to build the new walls from Fermacell (TM) boards. Our first thought was to build the brick wall, but as it turned out, the 30cm thick concrete floor was not strong enough to support several TONS of walls (yeah, brick wall weigh a lot more than one may think). Fermacell is somehow similar to the popular plasterboard, but is much stronger and three times heavier. And the mass is the key word in soundproofing.\r\n\r\n[IMG]http://img396.imageshack.us/img396/7527/dlr3eh0.jpg[/IMG]\r\n\r\nAfter rising the steel skeleton and feeling it with a heavy mineral fiber, the whole wall was covered with a Acoustical Sound Barrier - vinyl sheet material used to block and reduce sound transmissions through walls, ceilings, and floors.\r\n\r\n[IMG]http://img252.imageshack.us/img252/8198/dlr6vr0.jpg[/IMG]\r\n\r\nAfter completing the first wall, we build the SECOND wall to improve the soundproofing characteristics. So what we got is basicly "a room inside the room". The spacing between the two walls is 2cm.\r\n\r\n[IMG]http://img406.imageshack.us/img406/3654/dlr7wu3.jpg[/IMG]\r\n\r\nThe outer wall was covered with the more conventional plasterboards.\r\n\r\n[IMG]http://img53.imageshack.us/img53/7221/dlr13qk0.jpg[/IMG]\r\n\r\n\r\nto be continued.
