Ear The Organ of Hearingand Balance

• Sound waves enter the ear through the auditory
  canal and then travel through the ear drum, where
  they are converted to vibrations. Millions of
  tiny hairs in the inner ears cochlea convert the
  vibrations into electrical nerve signals, which
  are sent to the brain through the Eustachian tube
  for processing.
