Answer:
The hammer,anvil and the stirrup amplify the sound waves and send it to the cochlea. The cochlea receives the vibrations and converts it into electric impulse and sends it to the auditory nerve. The auditory nerve sends these waves to the Brain. The sound waves are collected by the pinna of outer ear.
