Range of human hearing is

The hearing is one amongst our five senses. The ears are the organ that helps us in picking up sound waves and vibrations. The Human ear can not hear the sound of all frequencies. 20 to 20000 Hertz - it is the range of hearing for a healthy person. 
 

This frequency is required to produce vibrations in the tympanic membrane. The number of vibrations that are produced per second is a frequency which is calculated in Hertz.
