I moved into a property where most of the switches & sockets had their polarities reversed or the connections loose. Other than constant shortings to appliances & bulbs burning out, I felt fatigue, muscle spasms & difficulty in sleeping. Even a telephone line resting on house wiring will cause haramonics & unhealthy em fields
If you are worried about being bugged, just use a Dictaphone or tape deck on record & sweep; there will be a feedback noise
The device you are using appears to be a non contact voltage detector. The changes in pitch is based on probes proximity to the ac voltage source. The rhythmic pattern to the sound you are hearing is corresponding to the audible oscillation at the frequency of the mains alternating current. It is the noise you household wiring makes when it's live.
There is a change in the tone when you move the fan's electric lead which indicates a loose connection. Check all power outlets & lighting.
Thank you for your comment.
I wish I was you...
Like this things are so hard to understand for me. And just got the devices and try using them.
I need to learn more about it.
Thank you very much again!
