A low hum in USA, Hamilton
Non-stop hum/vibration that started 5/12/2017, 196 Hz I would like to have access to a website that reports progress in identifying or possibly eliminating this horrible sound. I would also like to find out more about Dr MacPherson's frequency blocker and whether it is available for purchase. Should I ask him personally?
