I'm in my early thirties and could hear everything. Just like on my last medical, I could detect everything the hearing machine got. In the real world that translates into me returning things like computer parts or alarm clocks because of coil whining, which no-one else can hear, so there's always an argument... I read about some places even using high-frequency sound (which causes discomfort) in combination with classical music to disperse teenagers. You want Trayvon to move on, put on some 18th-century baroque music. That's one stop and frisk alternative they can't pin down.

As to the sounds… My wife and I and daughter listened. Daughter claimed to hear stuff. Wife and I didn’t.

Ah at 1080, that time heard everything up thru 18kHz, which puts my hearing at much MUCH younger than I am and would have expected (1984 Who concert inter alia gave me permanent hearing loss and mild tinnitis I s’pect)… and then the falloff to 19k was complete… I’m still a bit skeptical. I’m constantly saying “What?” and “Speak up, sonny”.

Apparently you’re supposed to set the quality to 1080p, the highest setting YouTube currently offers, and even then one of the higher-frequency samples gets garbled. You’re also supposed to use headphones.

Can compressed digital video (mpeg??) reliably transmit 16 KHz and higher sounds??
