Tab s6 lite weird noise

I got the tablet yesterday (2022 version) and when the screen is turned on I hear a high frequency sound like when I use a third party charger and plug in. (That's the closest I can describe how it sounds, or when the doctor tests your hearing with a headphone and different frequency sounds) When I turn the screen off it still sounds weird just lower and not that loud, like slight buzzing. I have sensitive ears so I can hear it even when my head is not that close to the tablet, but my parents can only hear it if they put it directly to their ears. I can even hear it when the book cover is on, but this way only when I put it really close to my ears. I guess a tablet should not make this kind of sound. I can live with it I'm just afraid that it will go worse in the future or something is faulty. Besides that the tablet seems great I like the s pen, but wouldn't recommend the 2022 version as I also saw people complaining about screen bleed issues. Fortunately my screen has no bleed, but the colors are way different than on my Samsung phone or other devices. So do you think it's a serious problem and I should return it, or I shouldn't worry about it?
