Sometimes I hear ringing in my ears.

It's not often, but I occasionally hear a brief ringing sound.

You know the beeping sound that occurs when adjusting the TV screen, right?

It sounds like for about 5 to 10 seconds, and I went to the hospital when I first heard the sound, but it was determined that there was nothing abnormal.
But even after that, I still hear tinnitus occasionally after several years.

Maybe because I didn't have any particular pain or anything, and I was told there was nothing wrong at first.

I didn't really feel like I needed to go to the hospital.

But now that I'm starting to get older, I'm beginning to worry.
