Wheel bearing Cayenne 4,5

Hello, currently have another problem with our Cayenne. During the ride, a bright grinding noise arises. Unfortunately, the camera or video does not record it, as the noise is probably still a bit too quiet. If I give gas it is usually gone, but I think the engine noise just overruns here. If I go down from the gas it is to be heard again. Furthermore, I have set it to “N” during the ride and it is clearly visible in idle mode. At higher speeds higher If you don’t know, it’s a bit less. Logically, it has to do with rolling, how fast and how slow. That’s why I tap on wheel bearings.. can you underline this assumption? Here too, thank you very much.
