Explain how the human ear works.
Working of an human ear:
The external piece of the ear is known as 'pinna'. Pinna gathers the sound from the environmental elements. The gathered sound waves get gone through the hearable trench in-ear. Toward the finish of the hearable canal, there is a slender layer called the eardrum or tympanic membrane. At the point when the compression of the medium arrives at the eardrum the strain outwardly of the membrane increases and forces the eardrum inward. Likewise, the eardrum moves outward when a rarefaction arrives at it. In this manner, the eardrum vibrates. The vibrations are enhanced a few times by three bones (the hammer, anvil, and stirrup) in the middle of the ear. The middle ear transmits the amplified pressure variations received from the sound wave to the inner ear. In the inner ear, the pressure variations get turned into electrical signals by the cochlea (a part of the ear). These electrical signals are sent to the brain via the auditory nerve, and the brain interprets them as sound.
