Hearing Loss Explained
... In order to understand hearing loss, we must first understand sound and how we hear it. Sound is made up of vibrations of energy which knock together to produce sound waves. The waves travel on air particles, spreading outwards from the source of the sound. Sound has two dimensions: A - ‘pitch’ or fr ...

Sound
In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.
