The new compact Octagon sound camera is the perfect solution for all challenging measurement tasks when localizing sound sources. It was manufactured in a sandwich carbon construction and is lightweight and robust. 192 MEMS microphones in an acoustically transparent frame guarantee high accuracy with the highest dynamic.

The all-in-one Acoustic Camera consists of:

  • Microphone array
  • Integrated data recorder and
  • Separate notebook with the software NoiseImage

Soundcam Octagon

This new system is perfectly suited for demanded measurements.
Whether performing detailed acoustic analysis of products and components, locating leaks in buildings and pipelines, or performing correlation measurements on rotating machinery for order analysis, the Octagon sound camera is ready to deliver accurate results.

Due to the dense microphone distribution, beamforming as well as holography measurements are possible – covering a frequency range of 30 Hz – 24 kHz.

From acoustic data acquisition to data analysis – this innovative sound camera offers all components for acoustic measurements, data acquisition and data analysis. This allows sound sources to be easily and quickly localized and analyzed.

The integrated data acquisition makes it a handy system with no set-up time. 12 digital and 4 analog channels can be directly connected to the Octagon for your additional sensors.

Use the sound analysis software NoiseImage for post-processing to correlate the additional information with the acoustic signals.

The fiber-carbon construction makes the octagon stable and light at the same time, integrated handles allow for easy transport or handheld measurements. All these features make the Octagon the perfect system for a wide range of applications in R&D, quality assurance, maintenance or environmental acoustics.

ACOUSTIC CAMERA: Leakage Detection on Windows and Doors

The all-in-one soundcam Octagon can be used to identify energy-saving potential by detecting thermal bridges and leaks on buildings.
In the video, the Acoustic Camera Octagon identifies leaks and leakage at a window as well as at a garage door. The power beamforming method used generates extremely accurate measurement data and acoustic images.
Similar to measurements with thermal imaging cameras, the results are displayed in color. The advantage of the Acoustic Camera is that the measurement is independent of temperature and can therefore also be carried out in summer.
