Hearing - JSS3 Basic science Lesson Note

Hearing is the process by which our ears detect sound waves and our brains interpret them. It involves several stages: sound waves enter the ear canal and vibrate the eardrum, which in turn vibrates the tiny bones in the middle ear. These vibrations are transmitted to the cochlea, a spiral-shaped organ in the inner ear filled with fluid and tiny hair cells.

The hair cells convert the vibrations into electrical signals that are sent to the brain via the auditory nerve. The brain then interprets these signals as sounds. Hearing is essential for communication, enjoyment of music, and awareness of our environment. Protecting our hearing from loud noises and taking care of our ears is vital for maintaining good auditory health.
