kiintoisa tarina pörriäisten maailmasta:
OTHER INTERESTING EFFECTS: INSECT WING SOUNDS
A very interesting electrical effect easily observed with the WR-3 are insect wing sounds caused when insects such as bees, flies, and mosquitoes fly within a couple of feet of the WR-3 whip antenna. The resulting sound is a buzzing sound very similar to what can be heard by ear, however, this effect is caused by electrostatic discharges each time the insect's wings flap. It is thought that electrostatic charges (static electricity) are collected on the insect's wings and then and dumped during each wing beat, creating a "modulated" electrical field around the insect at the same frequency as the wings beat. Large insects, such as wasps, Yellowjackets, Bumblebees and honeybees, make particularly strong buzzing sounds in the WR-3 headphones-easily heard when those insect fly within 3-4 feet (1 meter) of the WR-3 antenna. High-pitched Mosquito wing beat sounds can be heard the small insects fly within a few inches of the WR-3 Receiver's whip antenna.
Certain kinds of flies and other insects have much more electrostatic "buzz" from them than other kinds - Bees and Horse Flies, in our observations, have the loudest "buzz" in the headphones! This may also have something to do with the composition of the insect's wing, with certain type of insect wings more prone to static electricity accumulation and subsequent discharge. There may also be insect bodily electrical discharges generated within the insect's wing muscles that contribute to this effect, and a some believe that the insect's carapace ( outer body shell) has a piezo-electric effect similar to quartz crystals, but not much is understood about this phenomenon yet and further studies are encouraged.
