Amos Emerson Dolbear, an American physicist and naturalist, calculated the relationship between air temperature and the rate at which crickets chirp
Subsequently, the frequencies we report might not accurately reflect the true frequency of each chirp

Generally, a sine-wave chirp
signal with instantaneous phase [theta](t) can be described mathematically as c(t) = sin([theta](t)) = sin(2[pi][integral]f(t)dt), instantaneous frequency of which changes in time as f(t) = (d[theta](t)/dt)/2[pi].

He was heading straight in my direction closing the distance and as he passed by at 21 yards, I drew my bow, let out a chirp
and stopped him broadside.
A gene or two happened to change, or mutate, so that the cricket wing couldn't chirp

You can figure out the temperature by listening to a cricket chirp
Unless Americans understand from whom the gradual, persistent, and stealthily-imposed destruction of the family in America originated--and what organizations have been promulgating this process persistently and continually from behind the scenes for generations without so much as a chirp
from the already managed mass media--the problem of the family will get worse, and the impoverishment and enslavement of the American people by a central, socialist government will be complete.
boreale produces a distinctive calling song consisting of a series of chirps
normally composed of 2 to 3 pulses per chirp
To determine the actual radiation level, the owner refers to a table located on the back of the device with a chirp
Other survey sensors include a chirp
