The Beginning of Sound (Part 1) |

1. This first installment of the series explains how sound begins as vibrations in the air and is transmitted to the brain through the outer, middle and inner ear and the auditory nerve.
2. The outer ear collects sound, the ossicles in the middle ear reduce transmission loss, and in the cochlea of the inner ear sound is converted into electrical signals.
3. It presents three hearing habits, including reducing listening time rather than turning up the volume, moving to a quiet place, and getting your hearing checked if you find yourself asking people to repeat themselves more often, with Part 2 to follow.
