Harmonic Motion

Doppler effect shift in frequency caused by motion
Frequency sound tells you how fast the pressure oscillates
Pitch different sounds
Decibels loudness of sound
Speaker a device that is specially designed to reproduce sounds accurately
Longitudinal waves air is compressed in the direction of travel
Subsonic moving slower than sound
Resonance spaces enclosed by boundaries,with sound waves
Reverberation multiple echo
Fourier's theorem any wave form can be represented as a sum of single frequency waves
Frequency spectrum a graph that shows the amplitude of each component frequency in a complex wave
Sonogram a special kind of graph that shows how loud sound is different frequencies
Cochlea a tiny-filled organ in the inner ear
Rhythm a regular time pattern in a sound
Musical scale pattern of frequencies
Consonance more than one frequency of sound and the combination sounds good
Dissonance combination sounds bad or unsettling
Beat the phase of the two waves changes in a way that makes the loudness of the sound seem to oscillate
Variation comes from harmonics
