Based on the geometric measurements provided and the acoustical data measured, calculate the total absorption in this room in each octave band.

To do this, you will need to calculate the volume of the BPC. It is not a simple shoebox shape like the other rooms we have looked at, so this will require some effort. You will need to divide the floor into rectangles and triangles to find the area.

Once you know the volume, you can calculate total absorption by solving the Sabine equation for A instead of the usual T60. A = 0.16(V/T60)

Use the T60 data measured in the demonstrations. You may pick any of the data sets (sweep, MLS, balloon) for your calculations.

In the end, you should have a total absorption, A, for each octave band.
