One hertz

The number of times the vibration is completed per unit time is called the frequency. The unit of frequency is Hertz, and the vibration of 1 seconds is called 1 Hertz (Hz).

Sound can be quantified in both time and space. Quantification from the perspective of time refers to the cycle and frequency. Quantitatively in terms of space, mainly refers to amplitude and wavelength.

The time required to periodically vibrate once is the reciprocal of the frequency, usually in milliseconds (ms). For example, a pure tone with a frequency of 1000 Hertz, the period is 1 milliseconds.
