Interesting that he seems able to narrow down all orchestras to a 1dB
range like that. Reminiscent of the way undergrads sometimes write
down a lab experiment result to as many significant figures as their
hand calculator displays - regardless of having input figures only
roughly accurate. :-)


I've just flown back from the USA on a plane that was, according to the
"flight information" channel on the in-flight entertainment screen,
flying at a constant height of 37,000 feet - or 11277m. (Actually,
according to my calculations, to the nearest metre, that should have
been 11278m). Or is it possible that the actual height was 37,000 feet
plus or minus quite a bit, and that there was a spurious precision to
the "11277"?

I suspect your plane was more than 1 metre tall. :-) Did they say if the
height was measured to the seat of the pilot's chair, or to some other
reference? :-)

Slainte,

Jim
