They act as an acoustic filter

The pinna (also known as the auricle) collects sound waves and directs them into the ear canal, helping to localize sound sources.
The concha is the shell-shaped area of the outer ear that collects sound waves and directs them into the ear canal.

The three interconnected bones in the middle ear are called the ossicles:
- Malleus (hammer)
- Incus (anvil)
- Stapes (stirrup)
The function of the ossicles is to amplify and transmit sound vibrations from the eardrum to the inner ear, allowing sound waves to be converted into electrical signals that can be interpreted by the brain.
