Default Adding Multiple Absorption Coefficients

So let's say I have two different acoustic absorbers covering most of the area of a room,

All six surfaces with two independent absorbers ?

Not very realistic.


say a bass absorber and a higher broadband absorber. They cross over at around 250 Hz. If both have a 0.5 absorption coefficient at 250 Hz, how do I calculate a total absorption figure for both acting at the same time?


** The figures applies to the absorbers, not the room.

Nothing changes if one sits over the other.
