I Am A Healthy 15 Year Old I Don't Listen

I am a healthy 15 year old I don't listen to music with head phones but I have noticed that when someone speaks to me or I speak to someone or I hear a noise it sounds like a robot. I have cleaned my ears and I have found nothing, I'm not sure if this has something to do with my problem but I hurt my jaw on the side that I can hear the robot sound and this happened a few days before this started happening.
