 |
|
I have been researching sound deadening techniques for my RV 10 project and was interested to know if anybody has measured cabin noise with a DB meter. Obviously I am most interested in the 10 but would love to hear of the other models as well. It would be really great if somebody has measured before and after sound proofing their plane. Pretty hard on the 10 because of the double floors....you have to install the soundproof materials before pop riveting down the floor panels. If anybody is going to Vans for a test ride anytime soon maybe we could get a sound level from one of their planes to use as a baseline. Vans builds their planes as light as possible so they will be as loud as you can get. Just for fun I looked up the sound levels in the Cirrus SR20....95 dBA in cruise. Much louder than I would have expected.

I recently checked the sound levels in my RV-6. I was careful to note the levels at approximately ear level and position because I noted a couple of Db difference from low in the cabin to closer to the canopy(lowder as you get nearer the canopy level). I measured 97-98 Db in full throttle climb and 95Db in cruise. I have sound proofing under the front floor carpet and foam padded leather upholstery in the forward cabin side panels, otherwise no other sound proofing.
I am surprised that the the Cirrus is apparently as loud as the RV-6.
