Anybody used db meter for checking noise levels ?
Anybody used db meter for checking noise levels in their cars ? Looking for recommendations and what is tolerance level for DB9.

My car is a V12S on p-Zero tyres. I would really prefer less road noise at highway speeds, and I have done some very unscientific measurements. On my car/my tyres I find the noise unremarkable on good surfaces but annoying on poor. I was mainly trying to understand if the main reason for the noise was lack of sound deadening or tyre construction. I cannot recall the actual values I measured, but I used as a baseline the values from my dd which I believe are quite normal. The Vantage values were 8-10dB higher on the same roads. The only comparison I made at the time was with a Rapide on Potenza tyres . The Rapide was 5-6dB quieter than the Vantage.

Thanks! It has been few months since I had Pilot Sport 4S tires installed. Balanced and Aligned too. Very smooth ride. Recently there is wind noise which wasn't there before (thread here). I feel that wind is coming from driver side bottom of the windshield and also the point where side view mirrors are attached. If I keep my hand at the point where side view mirrors are attached, noise stops (!). Tech said that it is normal at that point, wind is going back after hitting windshield and SA said it sounds like any other DB9 which I am disagreeing. I never noticed these issues with my car before. So, when I go to pickup the car, I want to take a db meter and show them comparing with normal tolerance levels.
