No, it was an iPhone app. And those things are not accurate. I've tested a few against a real dB meter and most of them were off by 10dB here and there. Sometimes more, sometimes less. In the other thread about this, I think people reported the peak SPL getting up to like 90+dB? That's ridiculous. No car company would sell a production car that hits 90-95dB in the cabin. Laguna Seca's sound limit is 92dB, as measured from some distance from the track. But we are to believe the noise INSIDE the car is as loud or louder than that? Nope. Not happening.
Wish I knew someone in my area with a Touring. I'd love to actually experience first-hand what all the fuss is about.

I accept that the iPhone apps are not 100% accurate (but I made sure I downloaded the one with the best reviews for accuracy) but getting a specific db reading was not the point of the exercise. Rather, it was to measure the difference between the two cars back to back, on the same piece of road, at the same speed, etc. This showed 3-5 db difference. So while the actual db number reading may not be 100% accurate, the db difference is accurate because I used the same tool in the same conditions.

I have not measured my 964 RS. I might do that just to see. But even if it is louder, I don't really notice it because it doesn't drone. The quality of the sound is quite different. Bit like music, I can listen to Coldplay or Arctic Monkeys at full volume....but put Metallica on......and I am reaching for the ear plugs.

Thank you again Chris. I agree the same app would be good enough for comparisons. Especially controlling for other variables.
I wonder if the rumors that the touring has less sound deadening are true then. Has anyone pulled the carpet in a touring yet so we can compare to the carpet less pictures of wing cars?
I wonder if spoiler position has any effect on sound too?
Regardless, it can’t be as bad as when I took the rear panal and sound deadening out of the Exige S while it was still running the lotus sport (track only) exhaust. When the blower spooled up it was like having a motorcycle engine and an air raid siren in the car with me. I fitted a standard exhaust and refit the back panel and sound deadening (removing it was peak add lightness for me) and it was tolerable even at the 4K rpm it would cruise so I suspect the touring will be fine for me.

Perhaps someone has already suggested this and I missed it, but I didn’t see it in Chris3963’s post above: At speed, the Touring’s rear deck rises up, allowing the extra noise. The GT3 w/wing is fixed. All this talk about induction vents, fan placement between the two cars seems to ignore this fact when trying to prove the Touring is louder.
The primary compaint was the extra noise and drone at 140kph. Seems obvious the Touring would be louder, no?

Just returned from highway run. My GT3 (non-Touring) is not annoyingly loud at speeds between 70-90MPH. Subjective of course, and I'm anxious to compare to Touring.
If anyone near Greenwich, CT with a Touring is up for a brief comparison test let me know. If so, I'll pick up one of those fancy dB meters for our testing.
Not questioning Chris's observations/analysis, just would be satisfying to corroborate with another Touring.

Where are you heading? I'll be down around Alice's tomorrow. Might hit CA 9 to Santa Cruz. Otherwise, let's connect when you're back.

Oregon, Washington, Idaho, Utah and Nevada (from California). Leaving at 5AM tomorrow and will visit Crater Lake, then end up in Bend area. I'm gonna drive 2 (secret) amazing mountain roads in Oregon, which I've dreamed about for years to drive a Porsche on. One is only open a few months a year, due to winter snow. Any guesses?
My 17 year old daughter will be with me to Portland, so should be fun.

Hwy 242? Not trying to hijack your trip Chris88, but if you go to Ashland and take the Dead Indian Memorial Hwy east (it goes right by the Ashland airport) up to Hwy 140, then east about 7 miles to the West Side road, it will take you on a very scenic drive to Crater Lake. I grew up in Klamath Falls.

Very good guess...
There's another one I'll drive just east of Pendleton, that parallel's I-84 up into the Blue mountains that's fantastic...and no traffic...I love Oregon!
