Noise level/Sound deadening, how loud is your car on the highway Options

Hopefully some of you will help me collect some data. Download a Decibel Meter app for your phone, there's a couple out there for both android and IPhone.
I have a N/A 5sfe with a manual, and no extra sound deadening. Sitting at idle I'm around 40 decibel, if I spin it up to redline it gets to about 69 decibel, and up at highway speed its between 65 and 69.
If I push in the clutch it drops maybe 5 db. So what kind of levels are you getting? Especially you guys who've done some sound proofing i'd love to see what kind of readings you're getting.

I just tested mine and at idle I sit at 54db and reving the engine up I go up to 69db. I have removed all the interior off the floor boards and sprayed lizard skin on it.
this is my second celica that I have done sound deadner to. The first one I used cheap spray on kind from pep boys and I couldn't tell a difference, but the lizard skin I noticed a huge change.
also I have a loud exhaust so the lowish db reading is not bad.
