Webcam Monitoring of Noise Sources

Categories: ,


Video Images Synchronised with Sound Levels


Video images may be simultaneously recorded with noise levels using multi-channel data acquisition devices (such as Soundbook, NoisePAD, and Apollo Lite and Apollo Boxes), manufactured by SINUS Messtechnik GmbH.

A range of video cameras may be interfaced with data acquisition devices by SINUS.

The SAMURAI NoiseCam Option is required to record and playback video images simultaneously with the noise levels and frequency spectra. Irrespective of whether the sound level data is recorded as time history plots, instantaneous and statistical 1/1 or 1/3 octave plots, logarithmic or linear sonograms, waterfall plots, or other SAMURAI display modes.

The webcam video can provide a visual record of the activities of the subject noise source during the measurement duration (shown in the example screen shot as the central window of the train passby image).

Video documentation is very useful for noise measurements of passing vehicles, trains, industrial machines and other noise generating objects, events or activities.

The NoiseCam Option for SAMURAI is supplied with a basic webcam but a IP infra red black and white camera can also be supplied, or an iCube camera with a focusable lens.
