Working out RT60s for an oddly shaped room

How would you work out your RT60s for an oddly shaped room such as a hexagonal control room and the like?
I have the equation for a square or rectangular room.

Thanks a lot!

Anyone know where I can find a detailed list of absorption co-effiecients?

Measure, I'd say. Is this room really big enough for true RT60 calcs?

I'm confused about the question. Sabine and Erying use volume and surface area. Use those values from your room.

There are absoprion tables all over the net. What are you looking for?

Ah, my bad. Sorry, you're correct. I was under the impression that you needed the 3D model to work out RT60s.
It's fine, makes sense in my mind.
Thanks

With regard to the table of absorbtion coeffiecients:
Which is the best one that you've found (i.e. the most accurate, including the most materials, etc.)

Thanks again and sorry for my mixup.
