1.	explain how human ear work?
Answer» the outer ear or pinna helps to collect sound and passes to the middle ear. In the middle ear, the ear canal passes the sound to the ear drum. The ear drum vibrates and vibrates as the sound is emitted by the source and passes the vibration to hammer. Hammer passes the vibration to anvil and anvil passes the vibration to stirrup. Stirrup passes it to cochlea which passes it to auditory nerves which changes these vibrations into electric signal and passes it to the brain. The brain interprets these vibrations into sound. Working of Human Ear\tSound waves are collected by the pinna and then are directed through ear canal sound waves on striking the eardrum make it vibrate exactly the same way as the given sound emitting object.\tThe bones in thge middle ear start vibrating when eardrum vibrates. It helps in magnifying the vibrations. When the magnified vibrations reach the cochlea in the inner ear, the fluid in it starts vibrating.\tThese vibrationsare picked up by sensory receptors and are converted into electrical signals.\tThese electrical signals then travel to the brain which interprets sound.
