It can be expressed as the reciprocal of (1/B)-(1/A).

It's the form of an expression for the "room constant", a measurement in acoustics:

S*A
----
S-A

S is total surface area of a room, A is total absorption of a room in sabins.

It can be expressed as the reciprocal of (1/B)-(1/A).
Nice one. Thanks.
