In my home i have a room which is relatively silent. I can convert it into my home studio but have two problems.
1. The window. The sound of my noisy neighbors come from there whole day. What can i do on this window to reduce the noise? Instead of curtains if i put thick blanket will it help?

2. Door : On the right side i have this door. The noise passes through the wooden door. Also the noise passes through the gap between floor and door. What can be done here?

Because of these two i have to wait till the environment gets quiet or its night. This leaves me with only few hours to record. If these two problems are solved then i will be able to record round the clock.
Any advice on both of these problems?
