This is a beamforming analysis example of a car door in NoiseImage4. The measurement was taken by the gfai tech Acoustic Camera Team with a white noise source inside the car, plus the speaker system. The set-up was recorded by a 48 channel Microphone Ring Array at 192 kHz sampling rate. The spectrum is the basis for the calculation of an acoustic photo of the door. Depending on the frequency range marked in the spectrum, different sound sources become visible.
