Not to be picky, but... Dynamat really isn't mass loading. In fact, mass loading in a car is BAD. Not in audio terms, but in the fact that you're loading the car down with mass. Dynamat is better compared to semi-viscous damping. The softer material absorbs the sound and resonances, rather than "sandbagging" them with mass. Okay, absorb isn't exactly right. Converts the sound to heat, instead of re-radiating as resonant sound. But you get the idea. The balsa/plastic sandwich probably operates in that fasion. That, and the different layers have different resonant characteristics cancelling each other's resonances out. Unlike undamped metal, which would have a single annoying resonance. |
