Image 10: Intensity of the sound source
4.1 Heatmap
The main view of the user interface shows the camera image with a heatmap overlay. The heatmap shows the location
of the strongest sound source (single-source mode) or multiple sound sources (multi-source mode). Each sound source
isshown by means of a single color according to the intensity of the sound source (see Image 10). The intensities range
from weak to medium to strong with respective color-coded schemes in green, yellow, and red, respectively.
In addition to the heatmap, the location of the strongest sound source is shown with a small crosshair. When taking
a snapshot, the sound arriving from the direction of the crosshair will be recorded and analyzed (Section 5: Air leak
detection features). The dB level of the sound from this direction is shown at the top of the screen.
