I need help!...I just moved into a nice apt but my apt bedroom faces the street and I can hear all of the street noise, cars, alarms, conversations,etc. and the windows let in a lot of sun so I can't sleep at the night or during the daytime. But the other problem is that the apt is old and I don't know if the acoustic plug/mat will work on the my windows. It is one frame, but with 2 windows that meet in the middle...what do you recommend?
