Otoacoustic emissions

Otoacoustic emissions are little sounds that your ears make that can be measured by a special machine. When you hear a sound, like music or someone talking, your ear sends a message to your brain so you can understand what you are hearing. But sometimes, your ear can also make tiny sounds that are too quiet for you to hear. These sounds are called otoacoustic emissions.

Think of it like this - imagine you have a little whistle in your ear that makes a sound, but it's so tiny that only a special machine can hear it. That's what otoacoustic emissions are like! Doctors and scientists use these machines to listen to your ear's little sounds and see if everything is working okay with your hearing.

It's important to check on your ears and hearing because if there's a problem, you may not be able to hear as well. So, otoacoustic emissions are a helpful way to make sure everything is working like it should!
