Innovation leader in acoustic cameras CAE Software und Systems GmbH

Inspector www.cae-systems.de See Sound and Vibration During the last years new technologies for the visualization of sound sources "acoustic cameras" became extraordinary relevant in the industry due to its practical and intuitive use. Acoustic design of a product is an important aspect of product development. Ease of use and obvious results give engineers a new sense - "See sound sources with your eyes". This accelerates product development, quality control and environmental measurements. Therefore CAE Software & Systems develops powerful and flexible measurement systems. Our acoustic...

The Noise Inspector is designed for quick setup to save time and start immediately with measurements. Therefore we designed a system which can be setup by only one person in about one minute. Immediately after setting up the hardware, the first acoustic pictures are only one mouse click away. CAE Software und Systems GmbH Noise Inspector is a Solution Noise Inspector Leakage detection.

The array design is an important physical property to deliver very high resolution results. Therefore we put a lot of engineering know-how into the shape of the arrays. Standard designs give results with poor resolution and/or poor dynamic range. Star Array Microphones: 48 Diameter: 1.6 m Beampattern -3dB width: ±1.07414 ° max side lobe: -5.53551 dB Simulation at 5 kHz Ring Array Microphones: 48 Diameter: 0.75 m Beampattern -3dB width: ±1.92012 ° max side lobe: -7.89909 dB Simulation at 5 kHz Concentric ring Array Microphones: 36 Diameter: 0.6 m Beampattern -3dB width: ±2.96055 ° max side...

Because the influence of the array designs is that significant, we created a portfolio of good microphone distributions (see below). Furthermore it is absolutly possible to create customized array designs to fulfill the customers needs. Bionic L-112 Array Microphones: 112 Diameter: 1.7 m Beampattern -3dB width: ±1.33044 ° max side lobe: -15.4284 dB Simulation at 5 kHz Bionic M-112 Array Microphones: 112 Diameter: 1m Beampattern -3dB width: ±2.13321 ° max side lobe: -21.7749 dB Simulation at 5 kHz Bionic S-112 Array Microphones: 112 Diameter: 0.6 m Beampattern -3dB width: ±3.30846 ° max side...

CAE Software und Systems GmbH Smart Vision Handheld Device Noise Inspector By using a tablet the acoustic camera can be turned into a very smart and mobile system. It is mounted on the backside and will be plugged into the acoustic camera. Acoustic pictures will directly displayed on the tablet in real-time. The simple software interfaces allows the user to start immediately acoustic investigations. Electronic noise Noise of a closing side window Up to 100 acoustic pictures per second over a broadband frequency Up to 60 optical pictures per second Real-time processing with high definition...
