Methodological guide for the acoustic study of rooms. Linearized approach

Since one of the major problems in sound reinforcement is the choice of system (localized or distributed), we carry out an initial linearization that reduces the problem to a single unknown: the number of sources N.

We'll see later that this conceptual reduction is mathematically equivalent to a transfer that allows all useful quantities to be evaluated from a single variable: the opening angle of the sources at 2000 Hz (see § 1.4 1.4).

The advantage of the initial choice (number of sources) is :
