air explusion - the passage of air through a tube; usually heard as a whistle or hiss.
arthropods - The largest animal phylum, including insects, arachnids, and crustaceans, characterized by segmented bodies and paired, jointed antennae, wings, or legs.
bending waves - the form of vibrations traveling through a substrate
bioacoustics - the study of sound production and reception in organisms other than humans. Also, the study of the effects of sounds
on living things.
Crystal Phonograph Cartridge (CPC) - A device that converts mechanical or acoustical signals into electrical ones, especially such a device used in a microphone.
energy attenuation - decrease in energy due to the absorption of the waves as it travels through a substrate. Decrease in amplitude.
Faraday Cage - An electrostatic shield made of a series of parallel wires connected to a common conductor at one end that provides shielding while permitting the passage of electromagnetic waves. Also, Faraday screen.
Faraday?s Law - a law stating that the electromotive force induced in a circuit is proportional to
the time rate of magnetic flux change linked with the circuit.
frequency - The number of cycles or oscillations per unit time in a periodic system.
magnetic field - an oscillating electric field and its associated magnetic field acting at right angles to each other and at right angles to their direction of motion.
neuroanatomy - the division of anatomy involving the study of the nervous system.
neuron - one of the two principal types of nerve cells in the nervous system, usually consisting of a cell body, an axon, several dendrites, and specialized axon terminals, that is able to receive and conduct electrical impulses.
neurophysiology - the discipline involving the study of the makeup and function of the nervous system; makeup of the nerves.
neuroscience - Any of the branches of science that deal with the anatomy, physiology, biochemistry, or molecular biology of the nervous system, especially as related to behavior and learning.
oscilloscope - an instrument that uses a cathode-ray tube or similar instrument to display fluctuating electrical signals on a fluorescent screen; common applications include the testing of electronic equipment and the monitoring of electrical impulses from the heart or brain.
phonograph cartridge - a transducer that is located at the end of a turntable arm and converts variations in grooves on a record, as sensed by a pickup needle, into a signal for processing by a phonograph.
preamplifier - A circuit that increases the strength of a signal from a low-level source, so that it can be amplified further without appreciable degradation.
propagation velocity - the velocity of electromagnetic movement through a given medium.
phylogeny - history of a species or other taxonomic group. Also, phylogenesis.
shielded cables - a metal wire running down the cable end of the phonograph cartridge sheathed in aluminum foil, acting as a Faraday Cage, reducing electrical interference from outside sources.
stridulation - the friction of two body parts, usually heard as chirping.
substrate - the medium through which vibrations travel
tibia - the inner and larger bone of the leg between the knee and
ankle; the shinbone.
transduction - the conversion of mechanical impulses into electrical impulses.
tymbal mechanism - the quick contraction and release of tymbal muscles, usually heard as a series of clicking sounds.
tymbal muscles - Used in arthropod communication. In leafhoppers, two muscles found in the tymbal mechanism in the abdominal segment that flex from convex to concave, transferring vibrations to the leg.
vibration - the oscillation of body parts such as wings; usually heard as humming or rumbling.
voltage - the potential difference or electromotive force as measured in volts. (electromotive Physical Chemistry. relating to or producing an electric
current.)
wavelength - The distance between crests of waves.
