2014 Chevrolet Corvette Stingray: Tunnel Blasting and Decibel Readings (Redux)

October 8, 2014

2014 Chevrolet Corvette Stingray

The last time I took our long-term 2014 Chevrolet Corvette Stingray out for the weekend, I did some sound testing. I wanted to know just how loud the Stingray was at wide open throttle in a tunnel, so I loaded my iPhone up with a few cheap apps and headed for the hills. I used two local tunnels, did two runs in both directions and I got a sound rating of 100 decibels. The problem was, 100 dB was the iPhone's limit, the microphone couldn't register sounds any louder than that. To get a more accurate reading, I checked out some of the Edmunds official testing equipment and went for a second run.

Ya know, for science.

This test is pretty simple. I roll both windows down, leave the Corvette's top in place, go through the tunnel at wide open throttle. Accelerate, redline, shift, repeat. In the same two tunnels, with one run in each direction I got a result that was almost exactly the same. The highest rating registered on the official Edmunds testing equipment was 100.7 decibels. Not quite in the range that causes prolonged hearing damage (115 dB or higher), but definitely in the wake-the-neighbors sound register.

If you read the last decibel test I posted with our C7 Stingray Corvette you already know that it is a bit quieter than its predecessors in all three of our standard testing categories (at idle, at full throttle and at 70 mph). Luckily, a bit of quiet on the highway doesn't mean the C7 has lost any of its snarling-V8 personality.
