I could only guess, since the sounds from yokes are usually
very high frequency waves, (~10 - 15,000hz~) this may give
the 'illusion' that the noise has stopped because these
frequencies are extremely directional (noise could have been
emanating from the top of the yoke). The lower the
frequency, the more 'omnidirectional' they are.

How does turning the yoke upside down stop it from
Buzzing?
