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.

90dB peaks. 70-75 dB average. (for my needs) This would be at the higher end of day to day volume for me. For example, I’m currently listening to Indian Classical at an average of low 60 dBs with peaks in the mid 70s. These are measured at the listening position.
Sound pressure peaks in the room are much higher than average sound pressure levels in the room. And the vibration nodes of a wall or glass window probably require “node dampers” for best results. That’s where the Marigo VTS Dots are suggested to be placed. Or any damper. I suspect the only way to find out is experiment.
I’d rather listen in a normal room with light and windows that is comfortable vs. an audio dungeon any day of the week.
