Hi,
  My listening room is next to the heat/air condition unit. Every time it runs, the room is kind of  noisy. Behind the room , there is fiberglass inslulation. I would like to hang something acoustically such as acoustic blanket or something not expensive like that to reduce or absort the noise. Please recommend .

THanks

Thanks. It's interesting and not expensive.
