In today’s episode Maddie is listening for sounds. First, she discovers how wearing a hearing aid can help us hear more clearly. She meets 7 year old Zara who uses a hearing aid, before visiting the audiology department in a children’s hospital to see where hearing aids are made. Maddie finds out what happens when we have our hearing tested. She listens to different sounds through headphones so the Audiologist can see how well her ears hear sounds. Maddie then uses her special microscopic camera to see the tiny parts of the hearing aid before showing us what it’s like to have one fitted. Next, Maddie heads to a whistle factory to see how they are made. She uses her special camera to see big, strong stamping machines cut shapes out of brass and finds out how the cork ball gets put inside the whistle when it’s too big for the hole!
