Hearing loss doesn't only affect older people. It has many causes, and can be mild or severe. Learn about how the ear works and what you can do to protect your ears. Find out about new technologies that are improving the lives of people with hearing loss. Level 3 readers are aimed at children who are reading by themselves and can grasp new concepts. Key words and captions help readers understand new vocabulary and more challenging sentence structure. This project has been made possible in part by the Government of Canada.
