Abstract
Acoustic pickup beams (sound beams) can be formed in a physical environment from a plurality of microphone signals. Each of the sound beams can measure acoustic energy in a direction of the respective sound beam. Directional decay of the acoustic energy measured through each of the sound beams is determined. Room surface acoustic properties of the physical environment are determined based on mapping the directional decay of the acoustic energy to the physical environment. Other aspects are described and claimed.
