Sound examples LoadFlow TeamB

All examples use audification, i.e. they take one-day segments of the data (96 points) and use them as a repeating waveform. (The repeat rate in most examples is ca 46 Hz).

Moving the borders of this data segment (say, to play the segment from Mon 12.15 to Tue 12.15) will produce a buzzing sound if there is a big difference between the values of the adjacent days at this time, because the waveform makes a jump at the loop point.

Sound example 1 - households

uses the households data channel; it moves through the days at constant speed, such that it covers a week in ca 13 seconds. in the second half, buzzing occurs: there are big differences at these day times. Note that this example was meant to be played interactively with the mouse, so a rendering of it loses this aspect.

Sound example 2 - households and agriculture

compares the households data (left channel) with agriculture data (right); there is very little buzzing in the right channel, so very little change between adjacent days in households.

Sound example 3 - households and agriculture 2

same comparison between the households data (left channel) and agriculture data (right); the root frequencies are set to 50 and 75 Hz to make the channels easier to distinguish.

Sound example 4 - households and agriculture 3

sets the repeat rate much lower, and uses the power signal to modulate the level of a filtered pulse wave (at 50Hz, European mains frequency); now the shape of the daily cycles become audible as level changes.
