Confidence votes 7. The highness or lowness of a sound is determined by its frequency, measured in Hertz. (Hz) The lower a sound is, the more distance it can travel. A low sound is felt as well as heard. (Hence, the term Feel the Bass.) The higher a sound is, the less distance it can travel.
Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, high pitch means very rapid oscillation, and low pitch corresponds to slower oscillation.
