Weles SIMS with WA301 3D PU probe - a fast tool for sound source localization and sound field visualization
WELES SIMS - SOUND INTENSITY VECTOR MAPPING SYSTEM
Weles SIMS is a fast and reliable system for generating detailed sound maps along with a two-dimensional sound intensity vectors overlay of stationary sound fields. It offers a single-probe solution that uses scanning measurement techniques to create high-resolution acoustic images, which can be overlaid on a photograph of the noise source or area being analyzed—making it an ideal tool for identifying sources of buzzing, squeaking, and rattling sounds.
Built to harness the advanced capabilities of the WA301 PU Sound Intensity probe, Weles SIMS leverages the probe's unique features to generate sound maps and intensity vectors that reveal the distribution of sound pressure, intensity, and particle velocity, with no frequency limitations. The system allows for the visualization of virtually any sound field, from 20 Hz to 10 kHz.
KEY APPLICATIONS:
- Sound source localization and ranking – highest performance, spatial resolution and accuracy is achieved with near-field particle velocity measurement
- Particle velocity mapping
- Sound intensity mapping
- Sound intensity vector mapping
- Sound pressure mapping
- Sound power calculation
- Quick troubleshooting – listen to particle velocity
MAIN FEATURES:
- Ability to create sound images from 20 Hz to 10 kHz
- Real-time probe tracking
- Sound maps created within a few minutes
- Fully portable system - entirely powered from USB ports
- Can be used outdoors
- No need for specialized measurement facilities

System characteristics | |
Type of noise that can be measured: | Stationary – constant in time |
Measurement outcome: | Color sound map of either sound pressure, sound intensity or particle velocity overlaid on the image of the measured noise source. If used with WA301 3D PU probe, any sound map can also be overlaid with 2D sound intensity vectors |
Maximum measurable object size: | Limited by camera view field – Measurements are possible as long as the camera is able to see the measured area |
Measurement environment: | No limitations. Measurements can be carried out in any conditions provided there is a sufficient signal to noise ratio. Outdoor measurements are possible. Usage of wind-cap is recommended for outdoor use. |
Probe position tracking | |
Probe tracking concept: | Optical tracking. WA101 PU Probe is tracked via tracker that is attached to the probe. The tracker is equipped with two LED’s. The tracking algorithm is monitoring the location of both LED’s. Using two LED’s allows to automatically compensate for WA101 PU probe rotation. During the measurement camera image is darkened to increase the visibility of the tracker LED’s and ensure smooth tracking of the probe during the scan. |
Probe tracking features: | Tracking can be done in real-time or in post-processing. For special measurement cases tracking can be carried out on any user specified color. |
Camera resolution: | 1920 x 1080 (Full HD) |
Camera view angle: | 64° |
