Toronto is not known for its earthquakes but I believe that would be the loudest. db Sent from my iPhone > On Mar 16, 2015, at 9:38 AM, Tom Fine <[log in to unmask]> wrote: > > Hi Patrick: > > Maybe you could release a 2x speed version (an octave higher in pitch). Probably still taxing on the woofers, but maybe a better idea of the impact of big guns. Back in my newspaper reporter days, I covered some heavy weapons demonstrations at Fort Drum, NY. Big guns make big noises, to say the least! I was happy to be on the sending end of the business, as opposed to the receiving end. > > This brings up a question for the house -- what is the loudest naturally occuring sound as far as SPL's -- a massive earthquake, a massive hurricane or tornado, or the thunder after a big nearly lightening-to-ground strike (or perhaps the thunder overhead after a big cloud-to-cloud strike)? As far as human hearing goes, I'd think thunder would sound loudest, but I wonder if earthquake is most SPLs because of the subsonic waves? > > -- Tom Fine > > ----- Original Message ----- From: "Patrick Feaster" <[log in to unmask]> > To: <[log in to unmask]> > Sent: Monday, March 16, 2015 9:10 AM > Subject: Re: [ARSCLIST] "Sound" of the end of WWI > > >> The sound of the end of World War One certainly seems worth trying to play >> back.
