High pitch sound from speakers when speeding up

:
2016 Mazda CX-9 GT
My 2016 CX-9 has a high pitch sound coming from its speakers almost like when there is a bad ground. Has anyone else had this issue? Its barely noticeable when the radio is on but when muted or no music you can hear it while speeding up.
 
Hi, Yeah it sounds like white noise or something like that even if you mute the sound it's still there, I've asked the dealer to report this issue to Mazda themselves they said they'll do it and that this is with all Mazda CX-9's (2016-Current) btw some people cannot hear the noise you're referring to =)
 
I definitely haven’t heard it in my 2016... I guess I’ll pay closer attention next time... do you guys hearing it have the Bose sound system?
 
Yup, turn the volume up a bit while no sound is playing you'll hear the white noise but apparently not everyone can hear this (older people and if your hearing is not that stronf, a friend of mine who's always listening to loud music wasn't able to hear the noise while many heard it).
