Why would you want to make the cable wet? That's what dampen means. I believe the word you're looking for is "damp".

Certainly it could be damped, but not by traditional means, as there's nothing to push against for damping at the free end, and no effective bracing near the middle to attach damping equipment.

FTFY

Are these the jerks that call me twice a week with my "final notice" to be able to lower my mortgage and credit card rates? And won't identify what company they are? I'm on the Do Not Call list. I've ignored them for weeks, just deleting their message. I've tried telling them I don't have a mortgage and don't use credit cards. (It's true.) I've asked them nicely not to call me anymore. I've offered to buy them a dictionary so they'd know what "final" means and wouldn't look like idiots. I've told them no way would I do business with a company with ethics like theirs. The last time I talked to someone, she said hurriedly, "You're going to keep getting called.", and hung up. I hope it's them, and they got nailed for every time they called me. Twice. At least. And that this is their "final" penalty, using their definition.

Especially if you spell it backwards!
