On a calm day when the Hum can be heard outdoors, choose a place away from any buildings. Wearing a good pair of ear protectors, stand perfectly still and make an estimate of the Hum level. Next lay flat upon the ground and after a time of about ten seconds, make another estimate of the Hum level.. It will be found that the Hum level has decreased considerably and in most cases will disappear completely. Returning to a standing position the observed Hum level will return to its original level. It can be concluded from this that the energy of the Hum flows in a vertical direction and takes the path of least resistance.
It is important to note that if this experiment is carried out indoors the same result will Not be observed which leads to explain why the Hum appears louder indoors than outside. -- You received this message because you are subscribed to the Google Groups "Hum Sufferers" group.
