Need advice on how to sound insulate my room


Need advice on how to insulate my stereo room. My rig is is in the finished basement of my home. Problem is that the house is old'ish and the sound reverberates throughout the house - probably through the basement drywall and ceiling.

The upstairs floors are hardwood, with throw rugs. The walls are plaster on lathe.

The basement ceiling is drywall. However, the ceiling height is only about 8 feet, so a drop ceiling is not an option.

Not sure there's much I can do, but any suggestions have to be aesthetically nice or my wife will object.

Thanks

You might want to look at the tread on building a home theater on AVS forum. This is a very common topic in building a theater. Insulation is not a very good insulator. You should look at applying another layer of drywall, especially in the ceiling, using Green Glue between the layers. It is not really a glue, but a viscoelastic material that dissipates the sound. The Sound Proofing Company has a lot of material on their website on how to approach this problem. Ted White from their is active on the AVS forum. The bass is the hardest problem and low bass is almost impossible to totally block without a lot of rebuilding. But a Green Glue ceiling will greatly help the problem and will not reduce the ceiling height by much.
Green glue plus the extra drywall will really help with everything but the low base. The "glue" name is misleading. It really does work. Resilient channel is an option, but more work, plus you loss a little height. I don't believe that the resilient channel will give much better results than a green glue/drywall solution for the ceiling. You might give Ted White at Sound Proofing Company a call. He knows the details of both solutions.
