Sound Vocabulary~S.M

Definition's of Sound!

Decibel a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale
Compression the action of compressing or being compressed
Rarefaction diminution in the density of something, especially air or a gas.
Doppler Effect an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other.
Vacuum a space entirely devoid of matter.
Frequency the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
Hertz the SI unit of frequency, equal to one cycle per second.
Ultrasonic of or involving sound waves with a frequency above the upper limit of human hearing.
Infrasonic relating to or denoting sound waves with a frequency below the lower limit of human audibility
Echo a sound or series of sounds caused by the reflection of sound waves from a surface back to the listener
Interference the action of interfering or the process of being interfered with
Reverberation prolongation of a sound; resonance.
Pitch the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
Rhythm a strong, regular, repeated pattern of movement or sound

Wavelenght the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Trough a long, narrow open container for animals to eat or drink out of.
Kilohertz a measure of frequency equivalent to 1,000 cycles per second.
Megahertz one million hertz, especially as a measure of the frequency of radio transmissions or the clock speed of a computer.
Echolocation the location of objects by reflected sound, in particular that used by animals such as dolphins and bats.
