Well I might as well post on the subject, since I know full well that Doctors that tend to be unaware of such equipments use tend to believe it's all about the mind.
The only actual constant that seems to make sense is that drugs nowadays are money, and either villians make money through selling drugs illegally, or medical research groups prosper through the use of clandestine research and constant barrage of telling a patient that their ailment is only of the mind and treated by drugs.
I have been the victim of such experiments over here in the UK, and perceivably a victim of how the current understanding on the medical profession takes on such explainations. It's not like the experiments are impossible to replicate, in fact the theory is very simple:
Dolphins utilise a method of clicking with their back of jaw to generate a soliton reverberation that outputs a signal that they can pick up when it bounces off an object underwater. It's their method of sonar.
When Sonar is picked up it's reconstituted into a reference from their skull taking the sonar and causing their internal hearing to process the sounds reflection.
The same can even be said for bats, again high pitched signals are sent out and bound across objects, to which those signals return and are picked up by the bats ears (which are usually large) and the reverberation of their eardrums allows them to process the information.
Both of these animals have Sonar in common, however us humans are incapable of generating a sonar stream naturally, this is why those that are doing are most definitely not the individual that suffers from events, and the reason why most people that suffer this complain so much about whats going on.
The human varient uses sonar projected from Antenna arrays, the reverberation of their skull is picked up by their eardrums and generates the capacity for a voice.
A voice can be projected to a person, as for a mike pickup, I haven't quite worked out the current methods, the original method was through the use of implants, not placed their by aliens or anything so bizarre. As they could be placed by being shot as a projectile to a person, blown into their eye in the wind, swallowed etc.
The implants in this case would just be used to keep a track on them, at least originally. However now adays with the equipment being trained for gene therapy, it's possible to gene-sniff an individual to work out if they are the person they are tracking.
There are other factors to mention to that are more about the actually usage of sonar on an individuals brain. Doctors will know that people that are subjected to this (although under the perception it's an ailment of a mental understanding) should notice that an individual can suffer irrational behaviour, or be irritable.
This is understood thanks to the subject of how microwaves actually cook something. I'm not in this instance suggesting they are being cooked, however the interaction of high frequency signals will oscillate their very atomic makeup so much so that memory will be effected, internal temperature will be higher than that of a normal person increasing irritability, irrationality is increased because it effects the very way that chemical signals interact within the brain.
There's even a theory that is being developed that such oscillations could generate parallels in the sense than an individuals thoughts are split through frequency into a multiworlds entrapy, where they will answer a boolean question different from what they internally here (One universe says "yes" and another "no"), which potentially causes the individual to argue that neither the "yes" or "no" was theirs.
As you can guess that causes a complete breakdown of how an individual associates their internal thought structures with themselves, far further than those doing "Observation Theory Research".
Now I'm hoping my explaination hasn't been too beyond what Doctors understand, since they have a nasty habit of not wanting to look for answers in any other field other than their own. I would suggest if you believe me to be absolutely wrong, to try experimenting on if any of the things mentioned could possible occur, afterall those that have been hiding them up for years are near enough a cult through their manipulation of governments in the sense that no one perceives they exist apart from those abused.
