Audible Sound and its Properties
The sound wave having frequency between 20 Hz to 20,000 Hz are called as audible frequency sound.
AUDIBLE
SOUND AND ITS PROPERTIES
The
sound wave having frequency between 20 Hz to 20,000 Hz are called as audible frequency sound.
Examples
of vibrating sources that produce sound in the audible range of frequencies are
drums, guitar strings, tuning fork, human vocal cords and diaphragms of
loudspeakers.
Properties
*
The frequency range lies between 20 Hz to 20 KHz
*
Audible sounds are moderate frequency sound.
*
These are produced by those objects which vibrate normally.
*
It can be heard by human ear.
*
They cannot travel through vacuum.
*
They undergo reflection, refraction and absorption.
*
Human sense these waves and it is used to share information.
