I’m autistic with relatively high sound sensitivity. I’m wondering if another autistic person in this community used any soundproofing in an apartment that actually reduced noise coming from a busy street. There are a lot of different products out there and I don’t want to buy something that doesn’t work.
Foam board is light and flexible, therefore bad at blocking noise. Plastic film is even worse, unless several millimeters thick like window glass. Acoustic foam is light and flexible too, that’s why it’s supposed to be glued to a wall or ceiling to connect the missing necessary properties to the foam so it can work.
Glass is heavy, so it blocks noise well. Adding a better window on the noise leaking one will help a lot.
I agree about the weatherstrips, but if the missing strips (or open-cell foam strips) are a purposeful air intake, then you’ll have a ventilation problem to solve after sealing the window airtight.
Fair. I had done this on my house, so perhaps the distance from the street meant only a small amount of noise needed to be blocked
