Production of Sound
Sound is produced by the rapid to and fro movement of an object i.e. vibration. The object set to vibration disturbs the equilibrium state of the particles in the medium and vibration keeps transmitting from one particle to another.
The vibration of the body is the primary source of sound’s genesis. The emission of sound continues as long as a body’s vibration remains. By traveling across a continuous elastic membrane, this sound generates a hearing experience in our ears.
As an example: When a tuning fork is struck, it vibrates and emits sound. The vibration will stop if the tuning fork is touched with your hand. As a result, sound output will be reduced. In the picture, as a tuning fork emits sounds, a pinball in contact with one of the tuning fork’s arms continually travels away from the arm owing to the fork’s vibration.
We can comprehend the origin and character of sound based on our everyday experiences. For example, if a metal object falls to the floor or is struck by a hammer, a sound is generated; but, if it is grasped by hand or a hard object. Sound is created by blowing on a flute, plucking a musical instrument’s string, or vibrating the membrane of a drum. As a result, it is clear that sound is created by vibration. This vibration generates waves in the medium, which oscillates the membrane of our ears, allowing us to perceive sound.
The vibration of a body causes the sound to be generated. The vibration of the body is the primary generator of all types of sound. Mechanical energy is converted into sound as a result of vibration.
Production and Propagation of Sound
Have you ever wonder how are we able to hear different sounds produced around us. How are these sounds produced? Or how a single instrument can produce a wide variety of sounds? Also, why do astronauts communicate in sign languages in outer space? A sound is a form of energy that helps in hearing to living beings. It is a form of kinetic mechanical energy which moves in a form of a wave. The sound waves show vibrational motion. Hertz (Hz) and Decibel (dB) are widely used measurement units to measure sound.
