So real quick I'm very anxious stressed and worried about my ears after what my coworker did. I was on the phone talking to my girlfriend when he drove right up to me and held the horn on a car and I think my tinnitus might have spiked as a result and now I worried it might be worse then it was. My left ear also kind of hurts but that could be from my anxiety and fear around the event. Also I looked it up and a car horn is only 110 decibels max but he pretty started at 8 feet and held it until he was right up to me (3-5 seconds or so ) I dont think that is long enough or loud enough for it to cause any hearing loss or damage. I was having such a good day until that happened.
