Hey kiddo! An auditory evoked field is something that scientists look at to see how your brain responds to different sounds! When you hear a sound like a beep or a bop, it travels through your ears into your brain. Scientists use special tools to measure the activity in your brain that’s caused by hearing that sound. They can use this information to learn more about how your brain processes sound and to see if there might be any problems. It’s like taking a picture of your brain to see how it works! Cool, huh?
