Did I harm my babies hearing??

Hey guys!

So I was out on the deck at work (the train tracks run right next to it) and I was on the phone. The train came by and it hit the horn twice as it passed next to me. It hurt my ears so bad it made me feel nauseas!! 😖 Do you think that bothered my little guy? I’m 22 weeks. I’m worried it was so loud that it damaged his hearing.

I know that may or may not be crazy but I felt like it bothered me so bad that I feel like it might have got to him.

Thank you for your help!
