A huge difference
We renovated our home and put a music room above our garage, trying to isolate my 15 year-old son and his drums, as well as my guitar amps, from the rest of our home. Needless to say, until we set up our new ClearSonic panels, when my son practices his drums it was still difficult to carry on a conversation downstairs. No longer! The drum shields have reduced the sound downstairs by 90%. Thank you!
