Chimney noise stoppers

This was a post about Chimney balloons as a noise stopper or noise barrier found on Google groups at this link: I thought it was interesting. http://groups.google.com/group/alt.home.repair/browse_thread/thread/5d0efc3c31e9eac4?hl=en

Q: I’m having troubles with my fireplace insert. I’m having a quite tall chimney and for some reason, there’s no top or bottom damper in the chimney. When’s a windy weather, it makes very unpleasant noise in the fireplace insert, I hear the wind very loud. How can this be solved, please? – Matt

A: I was having trouble with street noise and pigeon cooing noise coming from my fireplace chimney. It was quite annoying, especially at night. I put in a Chimney Balloon to buffer the noise and it has helped quite a bit. It seems to have stopped some of the cold air passage as well. I also put out some of those pigeon spikes near the top of the chimney but that didn’t deter the little flying rats.
