Know about your hearing Hearing is the sense by which sound is perceived. Our brains differentiate between sounds by recognizing differences in volume (intensity) and pitch (frequency). As we develop from infant-hood, we are constantly listening to sounds and speech around us. As our brains begin to attach meaning to sound we learn to recognize sounds and voices and then learn to understand the meaning of words and speech. After much listening, we begin to learn to speak. In this way, hearing is necessary for the normal development of spoken language which is an essential part of communication. How do we hear? In order to hear normally, a complete and clear signal must be transmitted to the brain from the external environment via the outer ear, middle ear, inner ear and hearing nerve. Sound is gathered by the outer ear and sent down the ear canal to the eardrum. The sound causes the eardrum to vibrate which sets the three tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear to move. The movement of the inner ear fluid causes the hair cells in the cochlea to bend. The hair cells proceed to change the movement into electrical pulses. These electrical impulses are transmitted to the hearing (auditory) nerve and up to the brain, where they are interpreted as sound. hearing aid in rajkot, hearing aid in junagadh, hearing aid in jamnagar, hearing aid in bhavnagar, CONTACT 303/304, Golden Space Complex, 21-Sardar Nagar Main Road, Opp.ABC Medical Store, Yagnik Road Touch, RAJKOT.
