NEW: siCamera now with our new SoundFlow Sensors.

siCamera allows you to directly observe and film the sound flow through a surface. The fast, wide-band camera has a wide dynamic range, since the sound field is directly measured and not calculated. As a result, highly accurate, direct observations of the sound emission are possible under various operating conditions for the first time.

Wide dynamic range

The sound flow is directly determined by the sensor surface using a sensor array, which allows a dynamic signal range of more than 40 dB even with low frequencies. This is considerably more than any other acoustic imaging process has provided so far.

Wide frequency range

The use of actual sound velocity and sound pressure sensors allows a direct, wide-band measurement of the sound intensity over the entire audio range. The typical accuracy limitations and frequency measuring ranges of conventional sound intensity probes (pressure difference) are no longer valid.

Documentation of object image and sound flow

The object image is displayed via an optical camera. The sound intensity is shown as a semitransparent colored surface in front of the image. This permits acoustic events to be seen and documented directly on the object structure.

Selectable frequency range

The frequency range that is displayed and heard can be freely selected for online monitoring and audio replay of the recording, which makes it possible to focus on problem regions.

Various probe configurations

Probe dimension and number of sensors can be easily configured.
Bandwidth and number of probes can be adapted to the requirements and increased along with the available computing power.

Easy adjustment and reliable documentation of the operating states

The measuring ranges of all sensor channels are set at the same time using a few central parameters. The data recording format allows memory-saving recording and the selection of an interesting frequency range at a later time.
The parameters for the analysis do not have to be taken into account during measurement.

Sound intensity mapping of harmonic orders

The coupling with r.p.m. pulses allows orders to be displayed in an r.p.m. -synchronous way as a sound intensity map over the r.p.m. (in preparation).
