the voices in my experience are pre-programmed externally to your body to create an environment of control and deception. the sounds were hearing are like real sounds, but work from resonating bone and using piezo resonation from chin/teeth/neck/torso
the resonances are blocked by external pyrithione zinc. they program by heterodyning messages with external sounds. such as trains/planes, cars, tv's or speech.
ignore the voices, and work on finding the object like refridgerators which the signal is bounced from/. what i did was paste aloe vera mixed with onion/coal tar soap on non shiny side of tin foil, folded it and shaped into a bowl walked around the house listening for a reaction of blocking. for me under the fridge, and top. be safe, ignore the bastards, and be scientific.
