How Loud Is Your Disco
Finally got everything working with the Disco and she seems like she is running smooth. All the same, it’s a little bit louder than I would want. I thought I would take some time to take some measurements with the Sonic Tools app.

Baseline
Benchmarks
I’d be interested in knowing how these readings compare to others.
I am also planning on learning a bit more about this tool as an audio oscilloscope to see if I can create audio “fingerprints” for different parts of my truck to assist with troubleshooting. Some guys from MIT we’re working this theory into a diagnostic app.

Idle to highway speeds

Baseline
- 32” cooper AT tires
- not running A/C or Heater
- Stock exhaust
- 4.6L engine with Kent Cam
- Using iPhone XS with sonic tools app
- iphone was on top of dash
Benchmarks
- my office is about 35db
- Inside the rover parked w/ engine off is 30db
- idle is between 60-70db
- 25-40 Mph was loudest 70-80db
- 60-70 Mph was between 68-75db

It's never going to be a Rolls Royce but I find my Disco to be on the low side volume-wise. I don't have any actual numbers though.
If you have to remove the headliner for any reason, it's a good opportunity to add some sound/heat insulating material up there. It really quietens things down a lot.

I will, but I'm not finished rebuilding my engine.
I also only have the radiant barrier on the floor and sides of my D2.
I have yet to put it above the headliner.
However, I did put the RB above the headliner in an F250 that I have since sold. Quieter and less heat was very noticeable.
Before I even finished the floor and sides of my D2 I could tell a noticeable difference in sound. Almost the same effect as putting a blanket in a base drum.

I used metal hvac tape to attach the pieces to each other too. The material cuts and forms very easily, but will not tear.
It doesn't need an air tight seal either, just something to hold it in place until you get the trim and carpet back in place.
Same for the headliner, you can try attaching it/pushing edges in place, to the inner roof rails, and a few spots of silicone to hold it against the roof temporarily, just until you get the headliner back in.
Or, again, a few spots of silicone to hold it on top of the headliner board itself. Enough to hold it on until you get the headliner back in(how I did my Ford).
