Kinda disagree with the above statement from FOX.
It's called a shock ABSORBER as it absorbs bumps
and irregularities on the driving services at all
speeds.
If your shocks are kinda stiff for setup it could cause
a rough ride which in turn can increase road noise.
Did some googling .
Here are 3 links discussing issues with abnormally loud
Power Steering Pump,
Active Noise Cancelation System,
HVAC system
There is also a pedestrian warning system mentioned in one
of the links that makes a high pitched sound .
So maybe your loud interior noise is caused by one of
these or a combination of the three.

One thing you may want to check is tire pressure . Depending which tire came with your
Jeep . If using an All Terrain dump it down to 30lbs. Wouldn't be surprised if dealer has
pressure maxed out. That can cause a stiff ride while also increasing road noise .
