Sound Unit Flashcards
Define Vibrations
Rapid back and forth movements of particles or objects, often producing sound or transmitting energy.
Define Compressions
Regions in a wave where particles are closely packed together.
Define Rarefactions
Regions in a wave where particles are spread apart.
Define longitudinal
A type of wave motion where particles oscillate parallel to the direction of the wave.
Define wavelength
Distance between two successive points in a wave with the same phase.
Define frequency
The number or cycles of a wave that pass a given point in one second, measured in Hertz (Hz)
Define pitch
The perceived frequency of a sound, determining its high or low tone.
define amplitude
the maximum displacement of particles in a wave, indicating the intensity or loudness of a sound.
Define transverse
A type of wave motion where particles oscillate perpendicular to the direction of the wave
Define medium
the substance through which a wave travels (eg air, water, solids)
Define density
the amount of mass per until volume in a substance
Define echo
reflection of sound that arrives at the listener after bouncing off a surface
Define ear canal
the tube like structure that leads sound waves from the outer ear to the eardrum
Define choclea
the spiral shaped, fluid filled structure in the inner ear responsible for hearing
Define auditory nerve
the nerve that transmits signals from the cochlea to the brain, enabling the perception of sound.
