Understanding the Ear and Hearing

The video tutorial introduces the sense of hearing, featuring Dr. Kim Audit, an ear specialist. It explains sound waves using a drum and describes the ear's structure, including the outer ear, ear canal, and eardrum. The middle ear bones—hammer, anvil, and stirrup—are discussed, along with their role in transmitting sound vibrations. The inner ear's cochlea and auditory nerve are explained, highlighting how they convert sound waves into signals for the brain. The tutorial concludes with a recap of the entire hearing process.
