The major steps involved in hearing sounds with our ears include:
-
Sound Wave Collection: Sound waves enter the outer ear (pinna) and travel through the ear canal.
-
Vibration Transfer: These waves cause the eardrum to vibrate, which in turn moves the tiny bones in the middle ear (ossicles).
-
Signal Transduction: The movement of the ossicles amplifies the vibrations and sends them to the cochlea in the inner ear, where hair cells convert them into electrical signals.
-
Brain Processing: These electrical signals are transmitted via the auditory nerve to the brain, where they are interpreted as sound.
For a diagram, you would typically label the outer ear, ear canal, eardrum, ossicles, cochlea, and auditory nerve.
