Wave frequency

Frequency vs. Time, consider the wave as the movement of a diaphragm.

This article is about the unit for frequency. For the car audio company, see Hertz (company).

The hertz (abbreviated "Hz") is a unit for frequency, defined as "cycles per second" of a phenomenon. In car audio, we will consider the phenomenon to be the movement of a speaker or subwoofer diaphragm (cone). For example, when reproducing a 35Hz note, a subwoofer will move through its full range of motion 35 times per second. 

ApplicationsEdit

Like other metric units, the hertz can be prefixed. For example, the most commonly used form dealt with in car audio other than the regular Hz form is kHz. One kHz is equal to 1,000 Hz.

Sound travels as vibrations. The average adult ear can hear frequencies in the range of 20Hz to 16kHz.
