3D sound field inside a square duct

A set of measurements were performed with Scan&Paint 3D to characterize the sound field inside a square duct. Inner dimensions: 42x12x12 cm with 1 cm open cell Melamine foam (EKI 116, 10 kg/m) attached to each wall. A 5 inch speaker (Visaton WS13E) was excited with a white noise signal. The acoustic dataset compatible with ParaView is freely available in the following link:
