Myself along with countless others have experienced a terrible HUM noise that is likened to the sound of a diesel truck engine idling in the distance, but can never be located. Through research many have concluded that the cause is infrasound and broad band lines along with EMF(elctro magnetic fields) that are the root of the issue. Those in the medical profession dismiss it as tinnitus, others may just think your nuts.... Your not alone, nor are you crazy. The first step in helping the cause is to unite and petition against this debilitating phenomenon that can cause mental, physical, and financial distress, beyond the petition please contact your local electric company and make a formal compliant.. Together let's try and make a difference for our well being, and the well being of our environment and our children.
