Electricity if I remember correctly "buzzes" at about B flat. I remember reading that somewhere a long time ago.... so yes you are correct.... if
you are lucky enough to be in a place that has NO ambient sounds and are near electrical sources, like power-lines, transformers, etc. you
would/should hear a low buzzing at approximately B flat.
The first thing to do is to go and get a free hearing range check... people have different levels of hearing ability... from the near ultrasonic IE a
dog whistle to the very low long waves...
I personally can hear the Ultra sonic motion detectors and dog whistles... a very high pitched 'whistle' Being in the alarm trade at the time it
was a pain literally...
There are all sorts of appliances that put out all levels of hums and whistles that you are normally not aware of until its all shut off...
Electricity in wires certainly gives a hum... just go near a big power station
where its concentrated...
High pitched 'whines' even if you cannot 'hear' them will still effect you and can literally drive you crazy if its for extended periods
On the other end of the scale we have very low frequencies... Earthquakes can create these but more ominous is the Military... They use these low
frequency sound waves for communication because they can go a long way... like LF Sonar under water..
X Files did an episode where people effected had their head explode...
Not as bad as that but it too can drive you nuts...
And to those 'experts' out there who think this is BS...
Environmentalists have long claimed that the U.S. Navy's use of sonar for training exercises unduly threatens whales, dolphins and other acoustically
sensitive marine creatures.

Conclusions on very high frequency noise
It should be noted for the sake of clarification that there are certain sound levels that can cause serious and permanent damage to human and animal

Noise-induced hearing loss
Any sound over 85 decibels (dB) will eventually cause hearing damage. ... Ultrasonic frequencies (sounds above the range of human hearing) can also
damage

You can also here the blood flow in your ears when you have absolute silence... This is the "Ocean" you hear when you put a sea shell over your ear
However all this has nothing to do with the VISIBLE ENERGY that this thread is about

"Poor" and "Home Owner" just does not compute
