We walked down the street to Pin Drop Hearing Centre to learn about hearing loss and hearing aids. We tested our hearing in a neat room with special egg shaped foam to silence sound. We also got to hear sounds (phone ringing, birds chirping) as if we had hearing damage or loss. We looked at and test out hearing aids. We also saw how hearing aids have evolved over time. They used to use horns in their ear!
We learned a lot of new things about our ears and hearing! The hair cells in our ears vibrate, and if we are exposed to too much loud sound those cells get damaged. Some people have stronger ear cells than others. Once our ear cells are damaged, they cannot be fixed or regrown. So we need to take care of our ears! No matter how much you pay for a hearing aid, our natural hearing is still best. We can lose our hearing from aging and exposure to loud sounds for a long time. Some people can be born with hearing loss. We should start getting regular hearing tests at age 50.
