AB  - The reverberant field of a room is driven by the sound power of a radiating source (i.e., the sound radiating in all directions). For audio applications, the signal driving reverberation effects is typically based on a microphone positioned somewhere that does not actually capture the sound power of the source and its associated spectrum. This paper describes how one can find an optimal microphone placement position such that the mean-squared pressure spectrum best matches the shape of the sound-power spectrum of the source. The technique is based on measured directivity functions. The results will help recording and sound-reinforcement engineers produce more realistic reverberation effects.
