If a loudspeaker cone is made to vibrate with simple harmonic motion at a given frequency, ... it gives rise to a sinusoidal disturbance in the atmosphere. This sound is known as a pure tone. Examples of noise sources which contain pure tones include fans, engine exhausts, pumps, compressors, gears, bearings and electric motors.  6, record 1, English, - pure%20tone
