2018 RT LTD ..noise

Not sure if this has been addressed before or even asked..here goes.. I have noticed when I am cruising or speeding up to around 45.. a whirring sound becomes pretty evident.. not sure if this is normal or not.. it's not a metal sound, and maybe with my helmet on it makes it sound worse..
any ideas?..
Thanks for any suggestions or insights..

Mine seems to have a loud "whine" noise at 39mph. I have it but the dealer says it is normal. May be the same thing you hear.

It might be the drive belt starting it's vibrations.
