Q: I live in a large city so there is a lot of outside noise, and it echoes down my chimney. To make matters worse pigeons often roost on the chimney top and I can hear their cooing. - Ed
A: Hi Ed, Chimneys can function as a megaphone and carry noise right down into your home. It is especially annoying that birds tend to use chimneys as little rooftop lounges to hang out and sing karioke. A Chimney Balloon will really help to baffle down the noise infiltration. The air cushion inside the balloon absorbs sound waves and buffers out the sounds.
