I am going to be sealing the wall when making the basement a family room. Between the sump pump shooting out and the water traveling through the pipe, it's noisy. Anything that will quiet this?
You will never get rid of all the sound, but you might dampen it a bit by insulating around the pipes. You can use fiberglass insulation (batts) and stuff it around the pipe before you close them up. If you insulate the entire ceiling it will also keep the family room noise from disturbing people upstairs from noisy people down stairs. (I almost said from teenagers, but that might not be politically correct LOL).
