Use tight, heavily weather stripped, exterior entrance doors inside. I've done that and it makes all the difference.
Has anyone used "Quiet Rock" sheet rock in room?
Has anyone used "Quiet Rock" sheet rock on the walls and/or ceiling in their listening room? I am building a new dedicated sound room and I am trying to do all the "small stuff" (i.e. clean power and a well built/designed/acoustically treated room). All input would be appreciated.
