I'm new to the forum.
We have a Gen 3 (2015) RX350 that was just repaired.The wife fell asleep at the wheel - she's OK, and the car has since been repaired.

I have a question:
1. does anyone know the interior decibel ratings for this vehicle?

I ask because there seems to be additional interior noise since repairs. I don't know what the levels were prior and if I could get a ballpark idea, I could measure now and determine if there's been any degradation (more noise introduced from resulting repairs).

Thanks for anything you can provide.

Although you want to approach the problem scientifically, but at the end it will be hard to find a number to go bye.

Instead, I would suggest that you narrow down the source by binning the problem as

1. Rolling noise
2. Static noise
3. Engine based noise [under load or ideating]
4. Vibration noise [you can touch various panels and feel the vibes and also dampen the noise
5. Cabin noise or transmitted noise entering the cabin.

You can discuss your concern with the repair shop and they can revisit the items they fixed. At times during re-assembly, some fasteners could have been skipped.
