Idly flipping through "Physics for Entertainment, Vol2", 2nd ed (trans from
the 18th russian ed), Mir Publishers, Moscow, 1975, I came across the
following passage:-
""
It would really not be devoid of interest to wonder what we would really
feel if we did have magnetic sensitivity. Kriedel managed to impart a
sort of magnetic sensitivity to crawfish. He noticed that young crawfish
poked tiny pebbles into their auditory organs, which tended to weigh on
the sensitive hair comprising a component part of their balancing organ.
The human ear also has similar pebbles or stones called otoliths. They
are located near the main auditory organ. Acting in the vertical
direction, these stones point to the direction of the force of gravity.
Kriedel was able unnoticeably to insert iron filings instead of these
stones into the ears of the crawfish. When a magnet was brought up, the
crawfish disposed itself in a plane perpendicular to the resultant of the
magnetic force and force of gravity.
Of late a modification of these experiments has been staged on a human
being. Kehler glued minute iron filings to the ear drum, the result being
that the ear received the oscillations of magnetic force as a sound. [Prof.
O.Wiener].
""
Despite the fact that this stuff reads like pure Raymond Roussel, I suspect
that its all true. But who were Kriedel and Kehler, who was it that
volunteered to have iron filings glued to his eardrums and what is
Wiener's name doing suspended in brackets at the end?
Surely being able to directly sense magnetic
fields as sound has great applications for hi-fi and loud music fans.
By doing away with the cones of loudspeakers and headphones they could
listen to music of awsome loudness without disturbing anyone, with exceptional
fidelity to the original signal and without the annoyance of room accoustics
or local interference.
If anyone can point me in the direction of the original research papers
on any of this useful stuff, I'd be most thankful.
Regards.
