Automated, synchronized sound level meter and video analysis for quasi real-time control

At the measurement point at the edge of the runway, vehicle passage is detected by video analysis, triggering a trajectory shot and a few seconds of audio recording, on which the maximum noise level at the point of passage is recorded.

The latter is corrected at the reference distance to the measurement distance evaluated by video.

PC traffic analysis and identification of threshold violations

A web application provides near-real-time access to noise levels corrected for vehicle passages.

Passages above the 109 dBA threshold are highlighted.

The link to the proof file enables identification of the vehicle by zooming in on the bib (front/rear/side view).

Optional directional array to improve acoustic measurement accuracy and prevent false alarms

The directional acoustic array is patented technology derived from the dBFlash sound radar product, which isolates the noise of a passing vehicle over an area of +/- 5 meters.

This system guarantees that the noise level measured with the sound level meter is only linked to the passage of a single vehicle, with no restriction on the passage time between 2 vehicles.
