The hair-like structures inside your ear that vibrate to help you hear are called "cilia" or "hair cells." These specialized cells are located in the inner ear, more specifically in the cochlea. When sound waves enter your ear, they cause the cilia to vibrate. These vibrations are then converted into electrical signals that your brain can interpret as sound.

To find the name of the hair in your ear that vibrates to help you hear, you can conduct a Google search using relevant keywords like "hair cells in the inner ear" or "ear anatomy for hearing." This will provide you with scientific sources and articles explaining the structure and functionality of the cilia responsible for hearing.
