The sound we're hearing is the vibration of a material that is transferred and spread out through other substances like air.
The sound is transferred into the body through our outer ear.
The parts which gather and amplify the sound by resounding are called the earflap and the external auditory meatus.
As the sound comes into the ear, it reaches the eardrum, causing vibration. And then the sound reaches a cochlea via malleus, incus, and stirrup.
When it happens, lymph and cilia vibrate together, creating the sound signal which reaches the brain through the auditory nerves, and finally, the brain will analyze what sound it is.
We hear the sound through this process, which is called air conducted hearing.
