Auditory Canal: The auditory canal, also known as the external auditory meatus, is the tube-like structure that connects the pinna to the eardrum, allowing sound waves to travel from the outside world to the inner ear.
Eardrum (Tympanic Membrane): The eardrum, or tympanic membrane, is a thin, flexible membrane that separates the auditory canal from the middle ear. It vibrates in response to sound waves, transmitting the vibrations to the ossicles (small bones) of the middle ear.
Binaural Hearing: Binaural hearing refers to the ability to use information from both ears to localize sound sources and determine their direction, which is crucial for understanding sound intensity and sound level.
