Description

The requirement is for a 3D scanning system that is compatible with a Microflown USP Regular 3D Sound Intensity Probe

(https://www.microflown.com/products/standard-probes/usp-regular) that we already possess.

The scanning system should interface with this probe and provide synchronous position tracking and data logging. The software should implement post processing that allows a 3D sound intensity vector field to be computed from this data and then visualised and/or exported.

Required features:
• Sound intensity should be computed via the time-averaged cross-spectrum between the pressure and acoustic particle velocity sensors.
• The system should be able to import a 3D geometry model and calibrate the 3D tracked probe positioning data to this.
• The system should be able to track both the position and the orientation of the probe.
• The system should be able to compute total radiated sound power from the measured sound intensity data, both over a total enclosing measurement surface or on partial 'panels' to allow diagnostic sound power contribution from different areas.
• Export of data to Matlab .mat files and graphics to suitable image and video files.

The quote should also include cost for calibration of our Microflown USP Regular 3D Sound Intensity Probe.
