How loud is an average vibrator?😬

Hey, ladies❤️

So I’m 18 and I’ve recently worked up the courage to go to a sex shop and buy my first vibrator...

I still live at my parents’ house and obviously don’t wanna make things awkward and uncomfortable...for anyone😂

So I wanted to know- how loud is an average vibrator and which one is the best for discrete situations like this one?

Thank you in advance❤️
