Locating Sound with Norsonic Acoustic Camera

“Sound level meters do not provide information about where a sound is coming from. BKL has used the Norsonic Acoustic Camera 848 to identify the location of dominant industrial, marine, road, rail and indoor noise sources. It uses real time processing with 256 microphones mounted in a 1m diameter disc to perform this analysis. In this looped example, the location of a distant ship horn blast is obvious using the Nor848, illustrated with a sound contour overlay. Furthermore, the audio playback is specific to the cursor location so the listener can also “hear” the sound that is arriving from different directions.”

Aircraft Noise Animation #3 by SoundPLAN®

This is an animated noise map of the departure of a jet airplane. The animation was produced with the noise prediction software SoundPLAN® and shows the animated noise map and the level time histogram for different points of the map. The calculation is based on the German aircraft calculation standard AzB 2008.
