AB  - To fully describe the sound field at a listening position in an acoustical environment, the distribution of energy arriving from varying spatial directions is required, which this research accomplishes through the use of microphone array beamforming. Using the proposed technique, a multi-microphone impulse response measurement may be used to directionally locate any direct, reflected, or scattered energy arriving at the measurement location. This data may be graphically projected onto a sphere surrounding the measurement location or onto a virtual model of the measured environment, revealing the origin of the arriving energy. Preliminary measurements conducted at a prominent concert hall are presented, illustrating the analysis capability of the technique.
