Does anyone have suggestions for the best kind of windows to reduce
outside noise? The master bedroom has a 6-foot fully pocketed sliding
glass door facing south, and two narrow windows facing west and that's
it. The highway is towards the west so I was thinking that maybe
replacing the windows in the master bedroom might reduce the noise
there and in the queit of morning is when you notice it the most.

Also seems that when the air is more humid the sound is louder. Not
an acoustics expert (or even a novice) but is the thicker air when
it's very humid easier for sound to travel thru?

Thanks!

We have a similar situation, and found this website:

We haven't tried any of the products though. I was thinking that a
triple pane high quality sliding glass door might give similar
results, but I'm not sure. Our issue is at a vacation place, so we
may sell instead of fix this annoyance.

From what I have read, and I'm no acoustics expert either, you need
solid density to block sounds. The thicker the better. No gaps.

I did stay in a hotel in Barcelona one time and when I saw the hotel
was right by a very busy intersection I thought I wouldn't get any
sleep. Turns out the room with a window looking at the intersection
was actually quiet. They had installed two windows, one on the
outside and one on the inside. When I opened the inside window the
noise was significantly louder, and of course very loud when I opened
the outside one. There was about 10" of gap between the two windows,
I don't know if that matters.

Let us know how it works out, success or failure.
