'Quietest place on Earth' anechoic chamber

Utterly fascinating, check this out. Negative decibels. 

" This room in south Minneapolis, is so quiet that it measures negative 13 decibels. So quiet that Guinness World Records called it “the quietest place on Earth.” So quiet that film crews, acoustics nerds and curious kids journey here just to sit inside it. "

I once went into an anechoic chamber designed to test people with hearing aids. It was very un-nerving. I couldn't stand it.

Coffin.

Including its final location.

Guinness ever measure one of those?

I don't think so but Edgar Allen Poe wrote that it was impossible to hear anyone in one.

FYI

0 db is the human threshold of hearing. so that’s why you can have negative db as the negitive is sound that is below human hearing.


I argue the space center in Florida is the "quietest - Loudest" place on earth. just think ambient sound levels then 10-9-8-7-6-5-4-3-2-1......ignition, boom loudest place ...

ok not from silent but that range from ambient to the rocket ignition must be huge.


Ok maybe death valley July 16th at around 05:29:45 1945 silence then BOOM well you know what ... ;-)
