    Very scary! I have worked on power inverter systems (up 1MW), which produces both a mains hum as well as much higher frequency switching noises. That is, until it doesn't. That is when the loud noises…

    I've never had any of such experiences, nor do I often get close to large AC devices, but the hum still makes me anxious. The noise in some way reminds you that you are not safe and you could die at any…

    I think about the possible impacts over the long term. I'm assuming if you can hear the hum your close to the source.

     

    I worked in an RF environment for 17 years. I made every attempt to limit my exposure to RF in and outside the environment. I just short of wearing a tin foil hat.

     

    Story. We had a person stand in front of the antenna for a ground based aviation radar. The fail safe were in over ride to do some work. The individual had major health problems for a large part of his life.
