Quieted my cold air return
My furnace cold air return is located in my front entry hall which is right next to my TV room. When the furnace turned on I would have to turn up the TV volume. My goal was to absorb any sound within this duct. I used the 1 inch Echo absorbing cotton panels to line the cold air return duct and to line the blower compartment of my furnace. The noise reduction was noticeable, but not completely gone. My furnace air intake is very large/ oversized. Before doing this cotton panel install I removed my cold air return cover and their was no change in the noise. The noise I was trying to reduce was strictly blower / air flow noise within the blower. I no longer need to turn the TV louder when the furnace turns on. I used pin fasteners with slide on retainers along with construction adhesive. Overall the project was well worth it. The next step is to cover the outside of the cold air return duct and the outside of the blower compartment with MLV to dampen any other noises. I like this cotton panel product since it is not fiberglass.
