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"?
