Noise level in Vegas after insulation
I don't have any base line db noise levels before I insulated the doghouse and windshield ducting, but it is definitely much quieter concerning the eng. I think Jamie had some numbers that may serve as a comparison. If you still have those numbers Jamie, maybe you can post them.
Anyway I finished the ducting insulation and dropped my Vegas off at a Ford service center to have the trans. cable replaced. I took the interstate hwy. so I could get an even 60 mph and reading at which I normally cruise . Below are the db's at idle and at 60 mph. These numbers were with my wife's phone and a free app called Sound Meter Lite. I think a good bit of noise is road noise now, and may look into insulating underneath the floor in the cockpit area.
Noise meter at idle; 76-77 db
Noise meter at 60 mph; 77-81 db
