Acoustic Camera / sound source localization - Noise Inspector

Sound source localization is made very easy with acoustic cameras. Acoustic cameras are using Beamforming-methods for localization. The results are presented as a colored acoustic picture or acoustic movie and are easy to interpret for everybody. With this powerful acoustic tool it is possible to make acoustic optimization not just for sound design and NVH but also for failure diagnosis e.g. gear or leakage detection on engines. Futhermore the acoustic camera is an important tool for noise reduction e.g. machine covers or buildings.

The Noise Inspector is a unique modular system which makes it an optimal solution. It is possible to expand the acoustic camera with an additional microphone array to open up new fields of application. For very fast troubleshooting an upgrade with an intensity array or an acoustic compass (3D acoustic intensity probe) offers you a high performance acoustic camera for every application.

Our realtime software Smart Vision on the mountable tablet turns the acoutic camera in a handheld device with up to 100 acoustic pictures a second on the touchscreen.

The Bionic S-112 and M-112 combines the Beamforming-methods and acoustic nearfield holography (SONAH) in one microphone array turning it into a lowfrequency system for precise localization from 40 Hz.

The SoundCam family of products opens up many new possibilities for mobile and stationary acoustic sound source localization. There are four different SoundCam products for sound source localization. By using new microphones, analysis and localization of ultrasonic sources are possible. Optionally, software on the PC can be used to collect time domain data from all microphones for post processing. Either the Noise Inspector software can be used for post processing or wiht our open data format own software can be used.

The given frequency range below the microphone array are suggestions from pratical usage. The simple data acquisition is possible from 20 Hz. Of course you can use the microphone array of the acustic camera in different frequency ranges.
