Is this strange?

Hello everyone.

Jumping right in.

So, about 4 months ago I started hearing this high pitched tone in my ears. I didn't think much of it because I live in an apartment building; it is a normal occurrence for me to hear a tone like this when an older television is near. As early as I can remember, I would hear a really high pitched tone from older tv's, some much louder than others; some would be so loud it was almost painful. When I left the area the tv was at, the sound would go away. This tone I hear is not going away.

Here's where it gets strange. After about two weeks I mentioned the tone to my mom (we live together). She told me that she hears a tone too. The tone I hear is one of the higher frequencies, and can be replicated with a hearing test app. I played the tone I hear for her, and she couldn't hear anything (lucky her). She played a sound that was more like the one she hears, and it was very different. The tone she hears is more like a old motor boat from far away.

I scoured Google, and could not find a situation where two people got it around the same time. I did find this site, so I figured I would ask you.

Sorry for the long post.

Thank you in advance.
