AB  - A computer simulation using finite-difference time-domain techniques has been used to model the low-frequency transfer function between a loudspeaker and virtual microphones in a rectangular room. The model for the analysis was validated with measurements in an IEC standard listening space. Using the mean sound field deviation, the cumulative spectral energy decay, and the clarity metric, the properties of a sample room can be examined mathematically and visually. At frequencies between 30 and 100 Hz, sound pressure varies as much as 30 dB from one position to another.
