The term 'Hearing Organ' is often used to refer to the EAR, which is a three-letter word: EAR. The EAR is an organ of the body that is responsible for hearing and balance. It is made up of three parts: the outer EAR, the middle EAR, and the inner EAR. The outer EAR collects sound waves and directs them into the EAR canal, where they vibrate the eardrum. The middle EAR contains three tiny bones that amplify the sound and transmit it to the inner EAR. The inner EAR contains the cochlea, which is filled with fluid and lined with thousands of tiny hairs that convert the sound vibrations into electrical signals that are sent to the brain.
