And a link that talks about how much silencing this is capable of.

They should use some big speaker arrays that fire a negative pulse to cancel out the sound more or less completely. Like noise canceling headphones only bigger.

Active cancellation FTW.

How do you explain to airport security that you are taking these as carry-ons because ASR measurements showed they cancel noise better than the Bose QC and the Sony NC headphones, plus they have larger Dynamic Range?

Some kid got bullied at school, then later he found a dusty old lamp in the school's attic where he was hiding from the bullies, and he rubbed it and a genie popped out and told him, "Okay, lad, you woke me up from a long nap. You get only one wish, so quit playing with your toy cannon and make it count ...".
