Re: [Phys-l] Whistling at 2.4 atm



Supposing that an elastic interaction between the lips and airstream might be involved
it seemed sensible to suggest a mechanical whistle that would remove some experimental variability.
Whistles come in two flavors- the comma shaped whistle that sometimes features
a dried pea (or a surrogate) and the tubular whistle that has a similar knife edge
for separating the air flow. This latter would remove another variability - the speed
of rotation associated with blowing into the comma shaped whistle.

So for me - the tubular whistle which has a clear cut relation between internal
volume, length and emitted note would be a useful carry-along.

A friend is currently partaking of hyperbaric O2 treatments and needs to keep his mind off of the somewhat confined space.
One of his diversions was to try whistling.
Doesn't work.
His PhD is in Chemistry so he obviously had no clue as to WHY he couldn't whistle at 2.4 atm of O2.
I assured him that the lack of N2 probably isn't a factor and suggested that he try changing things like the size of the lip pucker, volume of the mouth, speed of the wind etc.

Any other suggestions for a fellow curious soul to try??

He was a wrestling coach for a while - so maybe he could try that the extremely loud and obnoxious 'two finger' whistle technique.
