Recently I bought a new construction home, and after moving in I was fairly dismayed at how loud the master bedroom is. The home is a quarter mile to the closest busy street, but it sounds like I'm living ontop of a highway. I can hear constant low rumble, and an "accelerating" noise.
The other bedrooms are rather quiet, so it has to do with something with the orientation and acoustics of the home. After some investigating, I realized I am hearing an echo coming off some apartment buildings behind the house. Front yard is rather quiet, while the backyard is loud!
The room has two exterior walls that face the side, and rear of the house, that I'm confident the majority of the sound is transmitted through.er (There is a vented attic above the room with 18" of blown loose insulation.)
So on the two exterior walls, I double hung 5/8" drywall with green glue between the sheets. (2x4 16" OC with pink insulation, exterior is 1/2" ply with vinyl siding). This helped a bit, by dropping the perceived average noise level. It is still rather hard to sleep comfortably in the room as the noise is unrelenting. So I installed large acrylic window inserts (Indows), and this seemed to do almost nothing. Investigating further into Indows, I realized their inserts are fairly poor performers for low frequency noise.

worse at 3 inches. (Surprisingly that is the space I have to work with)
This now brings me to the real portion of this post, I have seen several times on this forum the avocation for MagnaSeals acrylic panels. At this point I am very wary that this will work for me. The idea between MagnaSeal and Indows are similar, as with the materials. This leaves me with SoundProof Windows which are the next option. Does this seem like an appropriate application for SoundProof Windows? Finding information from someone that has gone from acrylic to SoundProof Windows has been difficult.
