I'm wondering if anyone with XC40 Recharges are experiencing any sensations of ear pain/pressure from boomy rumble & road noise in the car? Basically is the car painfully bass-y on rougher roads?
This is a huge problem in my Tesla Y and apparently also the Audi E-Tron & Mercedes EQC, and I'm wondering if the XC40 Recharge suffers as well. See this thread at the Tesla forums:
Ear pain/Pressure help
I guess it has something to do with the engineering choices for dialing in the "noise, vibration, harshness" characteristics of EVs with subframes that are hard-bolted to the main body without any bushings or buffers of some kind. The road noise is passed straight into the frame which starts resonating like a subwoofer.
"Simulating and Optimizing the Dynamic Chassis Forces of the Audi E-Tron"
"Reduction of Body Boom by Optimizing the Dynamic Axle Forces"
The noise is often super-low frequency, around 35Hz or so, which means you often "feel" it more than you hear it. In the Model Y the noise can be 95-100dB at even slow speeds! NOT good!
So at this point I'm wondering if this is inherent in all current SUV/crossover-style EVs or if the XC40 Recharge is better in this regard.
If anyone wants to measure it with a decibel meter or an app on a phone, be sure to use the dBC scale which detects low frequencies better than dBA scale.
