>>10834223Step one, detect the source. You will tell easily because unlike a magnetic attack this will reverberate off walls and sometimes make an audible humming. Literally just follow the sound with a decent detector. If it's a frequency that harmonizes with the skull, yet is too high for the human ear, then usually a dog will start getting rowdy. The funnest thing is to find the device, then reveal nothing until you bust down the door while the operator (if any) is still inside. He will likely shit himself. Then just beat him for trying something so stupid and call him a brainlet. (trust me, this hurts more than anything you could do to him physically) No helmet can help you unless it is rubbery so as to dull the vibration, as opposed to a magnetic "influence device", sonic ones can be especially tricky because they readily set up with cheap trinkets.
