Dynamat and similar products are supposed to be damping pads, or a constrained layer damping, and the idea is to add just enough to stop the panel resonating.
By adding too much, you go past the point of damping the panel and just end up mass loading it. It still works, just adds unnecessary weight. And cost. Especially if you're then putting mass loaded vinyl over the top anyway.
I've been looking through the 'what are you doing in the lockdown' threads and maybe I should make use of the isolation time (and 20+ years as an NVH engineer in the auto industry) to do a write up on making a Deafener less deafening!
