4. Study of transient reverberant fields in coupled spaces

Reciprocity of transitional regimes

Another aspect of the application of the principle of reciprocity to room acoustics is worth mentioning because of the practical implications it can have on the experimental determination of some of the criteria commonly used to assess the quality of listening spaces. This aspect, which could be defined by the expression "reciprocity" (or "non-reciprocity") of transient regimes, approaches room acoustics from a more perceptive angle.

In fact, this approach aims to answer a question whose practical relevance is no longer in doubt, and which could be formulated as follows: knowing that a source of transient signals placed in a room V ₁ (source room) induces in a room V ₂ (receiver room) a signal defined by a function...
