Maybe it's the location? Dallas is pretty flat, but Knoxville has sirens usually on ridge tops, so they can be heard for quite a distance away if you're in the right spot.
So, for my experiment, change it to a half mile. Surely nobody is going to play the long call more than a quarter mile off stage.... -William -----Original Message----- From: Bill Gross <[email protected]> To: 'The Horn List' <[email protected]> Sent: Sun, May 29, 2011 4:04 pm Subject: Re: [Hornlist] offstage brass The range of almost all outdoor warning sirens is one mile. Strong winds can decrease the range on the up wind side, but do not increase the range on the downwind side. This for a study performed for the City of Dallas when it was trying to determine how best to warn its citizen of impending tornados. I believe the study, by a consulting firm that slips my mind, was done in the 1970s. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Sunday, May 29, 2011 2:58 PM To: [email protected] Subject: Re: [Hornlist] offstage brass Actually, a good experiment would be to wait until they test an emergency siren. Find where it is and check the pitch with a tuner - if possible. I guarantee you that if it is a clear/fair day with a constant temperature, you can drive a few miles away and if you can still hear it, the intonation would be almost if not the same. -William -----Original Message----- From: Hans Pizka <[email protected]> To: The Horn List <[email protected]> Sent: Sun, May 29, 2011 3:53 pm Subject: Re: [Hornlist] offstage brass Sometimes, when waiting for Long Call, the spotlights in my back tried to grill my ass. Nice for the horn, as it gets warm & less moist accumulates. And at the edge of the stage opening, with these 10.000 W beamers, no problem of getting to flat, but rather sharp. As the old saying "If too flat, better too sharp !" ############################################# Am 29.05.2011 um 20:57 schrieb John Baumgart: > What's the temperature on stage compared to the termperature off-stage?
