Sound Filters for Open Windows
I want a sound filter for my windows. With all those smart people out there on the internet, it can't be so hard to make one. The sound filter works much like the mosquito nets I already have: It's cheap and you fasten it on the outside of your window. It'll keep out all the street noise, but it will let in the fresh air, which is especially good in summers.
Reward: I want sound filters for ALL my windows.
