Windnoise

Wind noise- I think the noise is coming into the bulkhead rather than into the car cabin where I hear it. My problem now is that this bulkhead seems to be highly contained and I am not sure how many apertures there are which might be available to me to stuff with some material. Any ideas? Mark

Greetings, My Subaru Outback 2019 model, 16,000 miles on the clock bought new, suddenly developed dire wind noise after repair work to electrical cables entering the bulkhead, the damage due to mouse . Work done by Subaru dealer. They and two other garages have been unable to fix it. Seemingly coming from front right of cabin in front of driver. Starts at 40mph and gives one a headache at 70mph. And I mean a headache. These guys all agree that the noise really is there and should not be. Has anyone some supernatural ability to diagnose the problem and then maybe I can get it fixed?
