The new acoustic camera localizes sound sources and visualizes complex acoustic information in different colours (as an acoustic photo and video). The device extends the vision to areas the eye cannot see. This is enabled by the method called beamforming where the position of sources in wave fields, such as ultrasound fields, is determined.

Thanks to the intuitive handling as well as pre-set profiles (e.g. for leak detection), even inexperienced users can correctly evaluate the results at a glance. With the highly sensitive array of 72 microphones and the IP54 protection class, it is perfectly suited for use in industrial areas. Compared to other array designs, the spiral array achieves an excellent acoustic dynamic range.

The wide frequency range, from 1 Hz to 100 kHz, allows the camera to be used in a variety of applications for the detection of sources of sound waves in the audible and ultrasonic range.

The acoustic images are shown in the high-resolution display at the extremely high frame rate of 100 fps in real time. In order to avoid rolling-shutter effects, a global shutter is implemented which allows the user to perfectly capture fast-moving objects.

The adjustable bandpass filter allows the user to focus on different frequency ranges and bandwidths based on the application and the emitted acoustic signals. Depending on what frequency the user is focusing on, he can detect sound sources up to 150 m away. Furthermore, the camera’s dynamic range can be adjusted to mask out sources of interference, even in noisy industrial environments. In addition, the device provides acoustic feedback via industrial headphones. This allows maintenance personnel to listen to the measurements in addition to the visual evaluation.
PC Software & Reporting

Recorded images and videos are stored directly on the device and can be exported for reporting to a PC/laptop. The software provides parameters for subsequent processing and analysis of the measurement results. […]
