Agree, then you could hold your hand against the panel before application and feel it vibrate. It was simple to measure, a tangible thing.
Yeah, that’s why I treated all the internals and drawers of my 3 drawer cabinet below my desk, the sub used to make it vibrate and resonant like a tin can but 2 kg of spare dynamat extreme later and it doesn’t make a squeak
