Mole crickets have three life stages, eggs, exponential horn.
3.
It was a pure exponential horn-loaded bi-amped quadraphonic sound system.
4.
Exponential horns are used in special applications that require minimum signal loss, such as satellite antennas and radio telescopes.
5.
Male mole crickets sing by exponential horn with twin openings at the soil surface; at the other end there is a constriction, then a resonating bulb, and then an escape tunnel.
6.
A spiral exponential horn shape ( sometimes called the " snail " ) is cast into the body of the horn, to better match the acoustical impedance of the diaphragm with open air, and thus more effectively transfer the sound energy.
7.
The researchers invented the exponential horn, and, on realizing that it needed to be nine feet long to reproduce the lowest frequencies on the new discs, designed a method for " folding " the horn into a cabinet of practical size.
8.
It has been documented that a train's whistle, when operating on compressed air, driving an exponential horn, has been measured at a higher decibel levels within the homes of nearby residents than within the cab of a vehicle sitting at the grade crossing.

The Strangers set an exceptional standard for live sound, using the best and'cleanest'equipment they could procure : German Dynacord microphones and public address systems, multiple guitar effects units, an exponential horn for the bass guitar, and carefully selected and matching guitars ( e . g.
