Photo-electric cells and a microphone built into the sculpture catch all the variations in the fields of color, light intensity and sound intensity.

If I plot a graph of transmitted sound energy versus air pressure-then when the air pressure hits zero, so does the sound intensity.
23.
Sound intensity or sound power measurements require pressure-gradient measurements, which are typically made using arrays of at least two microphones, or with hot-wire anemometers.
24.
Sound intensity is the acoustic power per unit area, and it decreases as the surface area increases since the acoustic power is spread over a greater area.
25.
In addition, response to pure tone stimuli may be limited, because in a sound field pure tones create standing waves, which alter sound intensity within the sound field.
26.
If I use for example twice the number of road-points, then the total sound intensity is approximately doubled . talk ) 14 : 44, 1 September 2009 ( UTC)

Before reaching the microphone, the sound source is subject to the Inverse-square law, which states that sound intensity diminishes as distance between the sound source and the microphone increases.

Rather than creating an image, instead I would like to make a contour map of the sound intensity . talk ) 22 : 35, 30 November 2009 ( UTC)

Ideally I would like to have contour lines of the sound intensity over the plane, but just being able to calculate the sound intensity at two different points will do.
