Audio analysis showed up the same characteristics of v2k
That is of a looped repetition of the sounds and also the sound bearing human vocal charecteristics if not always intelligible

To be blunt the voices captured by accident are v2k in nature and in effect
They attack in waves of sound as if carried in wave forms interacting with the surfaces of the cavity. Becoming distant to forefront in a manner that v2k alike oprates, sonetimes seeming to be carried on and mingled with other sounds such as traffic or water wtc.
But these v2k voices were in a very pristine enviorment and were only able to use wall caves and wood to vibrate off, unlike the v2k signals interacting with other sounds people are hearing in thier braisn whilst be subjected to the narrow targetted beam to the inner cavity of the ti's head and body.
