The so-called minimum audible angle (MAA) is formed with respect to the listener’s head by two sound sources at the same distance just auditory differentiable in position when sounded in succession. Here, a similar concept referred to as the minimum audible distance (MAD) is introduced, denoting the distance of two sound sources in the same direction with regard to the listener just auditory differentiable in position when sounded in succession. For the MAD measurement, an adaptive two-alternative forced choice procedure is proposed and evaluated using a circular Wave Field Synthesis (WFS) array in reverberant listening environment.
