You've
probably seen these on the sidelines at football games.
"Parabolic" mikes look like those little
satellite dishes--and they work under the same basic
principle. That is, the parabola works to concentrate
a weak signal. So anytime you want to hear something
that's very far away, a parabolic mike might be in order.
Examples include the quarterback barking plays or the
chirping of the rare yellowbelly sapsucker.
Good
parabolic mikes are a lot of fun--for example, you could
hear a private conversation from across the park. This
is why spies use parabolic mikes all the time. Gosh,
with a parabolic mike and night-vision goggles, you
could set up your own counterintelligence agency (Just
kidding. While the gear is legal, poking into people's
private affairs could land you in jail!)
