weaker sound sources. Note that sound sources considerably weaker than the strongest source will
not be shown. The
multi- source mode is useful for locating weaker sound sources. If you want
to examine these sources more closely, you can move and rotate the camera as well as use the
Zoom
buttons. Always keep in mind that any analysis is done in the direction of the crosshair on
the display.
Note, that if an actual sound source is large (for example, a large vibrating surface), the source
shown on the display might be smaller than the actual source. The source might in this case also
move around as you move around the surface, depending on which point of the surface is closest
to the UltraView. In this case, taking a snapshot and viewing it in the Cloud might help. In the
Cloud, it is possible to adjust the dynamic range of the heatmap with the slider below the image.
By increasing the dynamic range, you might be able to tell how large the sound source actually is.
It is often useful to take snapshots of interesting sound sources from several different directions.
The exact location of the source is easier to determine when viewed from different angles. Sound
sources can also be directional, meaning that the sound level will differ depending on the
direction.
6.3 Reflections
The UltraView can sometimes show reflections of sound sources. To tell a reflection apart from an
actual sound source, move around the object you are inspecting and examine it with the camera
from different directions. If the sound moves around or completely disappears, it is most likely a
reflection or interference. If the source stays in one place when you move the camera, you have
located an actual sound source.
The
multi-source
mode might also be useful when trying to determine whether a sound source
the camera displays is an actual sound source or a reflection. With the multi-source mode, you
might be able to see both the actual sound source and one or several reflections, and by moving
the UltraView around the object you are inspecting, you might be able to tell which of the sources
are reflections (
