[Concern] I sometimes hear ringing in my ears.

Sometimes I hear a high-pitched ringing sound, and I'm worried about it.

The sounds like beeping and other noises feel muffled.

I feel like I should go to the hospital, but it's not something I do often, so I'm not sure if I should go.

Once every three months? I really hesitate more and more to go to the hospital because I visit so rarely like this.

I wonder if everyone experiences this phenomenon occasionally.
