I have been experiencing something of late, but I am not sure if it is the "hum" that many people experience. In my case, it actually sounds like
a helicopter right over head but with out the "clapping" part of the chop. Some have suggested that it is the Air Conditioner, yet this happens
when the A/C is off as well.
This has been loud enough to hurt and I have to put ear plugs in to make it tolerable. This makes the throbbing hum fade to something rather
acceptable, but even then it doesn't fully go away. Others in my house do not hear it.
