Windows in a listening room


My 12.5' x 15' listening room has an 8'-wide patio door on the long side. I was concerned that the large glass area might be hurting sound quality, and even got an estimate on a sound-absorbing curtain—about $600. Then I watch this video1, and now I don't worry about it any more.

Glass is bad for sound. For starters it’s very transparent to rf. It also rings like a banshee and flutters like a wounded duck. The room is like the inside of a drum. Some ideas: Marigo VTS Dots for Windows, crystals, just open the windows, that helps the sound. There’s always Flying Saucers 👽 for Windows for the more adventurous, or the Silver Rainbow MagnaBlock from PWB Electronics, only $20.  

Whilst using absorption one must always be on the lookout 👀 for what Acoustic Revive refers to as “over-dumping.” It can sneak up on you, before you know it you’ll be living with over-dumping forever. It’s an excellent example of expectation bias, that absorption is always good.
Windows let in noise and light. I shuttered mine, more like doors really, solid MDF panels dramatically reduce noise and light. Closed flush, its almost like no windows at all.

When I first put them on it was fun to bring people in the room, close the door, let them get used to the quiet. Then close one shutter. Watch the look on their face. The noise that comes through a window, we are so used to it, its so nearly white-noise diffuse, its hard to notice until its gone.


geoffkait, I went and looked at Marigo’s tuning dots and must say:  the web site doesn’t do a great job of explaining their virtues.

@geoffkait   Does this serve 'less pressurization' (versus more)? Thanks.
I've got two large windows in my room that I was convinced were causing problems.Until I began placing bass traps and panels over them.It surprisingly did nothing to improve the sound.The corners and the front wall were the culprits.I live in a rural area so soundproofing isn't an issue.
