Microflown Scan & Paint 2D
MF002

Scan&Paint 2D is a tool to visualize stationary sound fields with an unmatched spatial resolution in full acoustic bandwidth. The system is a superb engineering tool for troubleshooting, soundproofing, or benchmarking all kinds of objects on the spot. It only takes a few minutes to complete an entire measurement campaign. Scanning results are translated into acoustic imaging by superimposed sound variations on a photograph of the measured object, allowing to localize the sound origin for either low, mid, or high frequencies.
Sound source localization is an important topic in the field of sound & vibration, from the product development stage to the end-of-line quality control. Scan & Paint is a fast, easy and accurate tool to visualize stationary sound fields with unmatched spatial resolution and full acoustic bandwidth coverage (20Hz to 10kHz).

Description Specifications

Product Full Description

Microflown probes enable the direct measurement of both sound pressure & particle velocity, thus the sound intensity can be obtained by taking the time-averaged cross-spectrum between both.

This allows for direct measurements across a broad frequency range (20Hz to 10kHz). Furthermore, the sensors are not highly affected by the environment and allow sound intensity measurements in situations with a high sound pressure over sound intensity ratio (p/I index). This unique feature makes the system a superb engineering tool for troubleshooting or benchmarking all kinds of objects on the spot.

High resolution mapping of: Particle velocity, Sound intensity, Sound pressure, Sound pressure contribution (available with the TPA module), Transmission loss coefficient (available with the TL module), Absorption coefficient (available with In-Situ Absorption add-on)

In practice, there are many cases where anechoic conditions are not applicable, for instance in an industrial manufacturing environment, or a car interior. Finally, a solution is offered which does not require any compromise when taking measurements even in acoustically challenging environments.

The tracking camera, which automatically tracks the position and orientation of the sensor, can be repositioned easily during measurement sessions, providing flexibility together with the ability to capture complex objects, such as a car interior in full 3D. Multiple measurements from different camera views can be merged into one full 3D project.
