Acoustic Shape-3D Sound Vectors on a 3D Model
TRANSIENT NOISES AND NON-STATIONARY MEASUREMENTS
Acoustic Shape enables to combine multiple measurements that share a common reference signal into one single project. As a result, users can localize complex sound sources with precision and also quantify noise effectively, even under time-varying operational conditions. This module has recently joined the Velo platform, expanding the usage of near-field acoustic data from 2D to 3D. As with Scan&Paint 3D, all test data is visualized around a 3D model of the device under test.

Product Overview
THE REAL 3D SOUND INTENSITY PROBE
The state of the art sensor used in the system is the three dimensional 1⁄2 inch USP probe. The sensor consists of three orthogonally placed Microflown acoustic particle velocity sensors and a sound pressure microphone. The sound intensity can be calculated by taking the time averaged cross spectrum of particle velocity and sound pressure. 3D Sound intensity vectors can be obtained without any frequency limitations covering a range of 20Hz to 10kHz. The small sensor size allows measurements to be taken with an unmatched spatial resolution.
INTEGRATING MULTIPLE MEASUREMENTS FOR ENHANCED 3D SOUND ANALYSIS
Acoustic Shape allows you to automatically synchronize and track the position of a 3D probe array, facilitating fast and efficient point-by-point measurements. This acoustic testing solution is especially useful for exploring non-stationary problems, visualizing transient noises or varying sound fields by using a reference signal to synchronize multiple captures. The software delivers real-time process control and noise visualization tools, along with a wide range of analysis options. This empowers users to better understand and interpret how the spatial distribution of sound emission fluctuates under varying operational conditions.
