I've had to learn breathing control even with the Telinga. When
recording in quiet situations I have to be careful to stay directly
behind the reflector and breathe quietly and smoothly.

Out with Lang last year with his ultra quiet setup we were constantly
bothered by cars on the road, about 4 miles away. And a airplane in any
part of the sky from horizon to horizon was a problem. And we were
recording frogs right out in front of his mics, hardly any distance at all.
