Explore the amazing parts of the human ear! Label and learn the function of each section.

The human ear receives sound waves as vibrations and converts them to signals that are processed by the brain. There are 3 main parts of the ear: outer, middle and inner. Sort the parts into the category they belong. Use your notes if needed.
