what are its audio specs (stc, nrc, db reduction, frequency attenuation data)? (to compare its price/performance).

NO SUCH NUMBERS TO MY UNDERSTANDING ARE AVAILABLE, I WOULD EXPECT THE NUMBERS YOU ARE LOOKING FOR ARE ONLY A MINOR IMPROVEMENT, FACT OF THE MATTER IF YOU WANT SPECIFICS SPECS ON THIS PRODUCT FOR THE PRICE YOU ARE LOOKING AT THE WRONG PRODUCT THIS IS A WALMART TYPE OF PRODUCT NOT A MACY'S

use for car insulation?

THIS WORKS GOOD IN MY CAR EXCEPT DON'T PUT IT IN AN AREA WITH HEAT IT MELTS.

When placed in the door will it block sound from going outside the room?

NO, this is very thin and will do little to block sounds either leaving a area or coming into a area. Spend your money on real soundproofing

Can I use this to protec my motorcycle fairings from the heat that generates my sports motorcycle?..I just got new fairings.

I think so. I used it under the seat of my gasoline golf cart To deadin the noise, gets pretty hot in the engine compartment should work for what you want. You can trim it with scissors.
