Using the Simple Hum Detector previously described and counting the number of pulses observed at various times of the day, a plot can be obtained showing the daily cycle of the Hum. It will be found that the perceived Hum level is inversely proportional to the pulse count, that is, the greater the pulse rate the lower the Hum level..
This is best explained using the surface of a lake as an analogy. If the surface waves are smooth, regular and in one direction then the pulse number will be high and easy to define, but if the waves are erratic and irregular the pulse count will be low and difficult to determine. It is at such times that the Hum produces its effects, appearing very loud and inducing headaches and nausea. -- You received this message because you are subscribed to the Google Groups "Hum Sufferers" group.
