    In contrast, using average power densities measured in microwatts per
    square centimeter, we have found that ****r effects which are
    transient, can be induced with rf energy.  Further, these effects
    occur the instant the transmitter is turned on.  With appropriate
    modulation, the perception of different sounds can be induced in
    physically deaf, as well as normal, in human subjects at a distance
    of inches up to thousands of feet from the transmitter.  With
    somewhat different transmission parameters, you can induce the
    perception of severe buffeting of the head, without such apparent
    vestibular symptoms as dizziness or nausea.  Changing transmitter
    parameters down, one can induce a "pins-and-needles" sensation.

    Experimental work with these phenomena may yield information on
    auditory system functioning and, more generally, in the nervous
    system function.  For example, this energy could possibly be used as
    a tool to explore nervous system coding, possibly using Neider and
    Neff's procedures (1), and for stimulating the nervous system without
    the damage caused by electrodes.

    Since most of our data have been obtained of the "rf sound" and only
    the visual system has previously been shown to respond to
    electromagnetic energy, this paper will be concerned only with the
    auditory effects data.  As a further restriction, only data from
    human subjects will be reported, since only this data can be
    discussed meaningfully at the present time.  The long series of
    studies we performed to ascertain that we were dealing with a
    biological significant phenomena (rather than broadcasts from sources
    such as loose fillings in the teeth) are summarized in another paper
    (2), which also reports on the measuring instruments used in this
    work.

    The intent of this paper is to bring this new phenomenon to the
    attention of physiologists.  The data reported are intended to
    suggest numerous lines of experimentation and indicate necessary
    experimental controls.

    Since we are dealing with a significant phenomenon, we decided to
    explore the effects of a wide range of transmitter parameters to
    build up the body of knowledge which would allow us to generate
    hypotheses and determine what experimental controls would be
    necessary.  Thus, the numbers given are conservative; they should not
    be considered precise, since the transmitters were never located in
    ideal laboratory environments.  Within the limits of our
    measurements, the orientation of the subject in the rf field was of
    little consequence.
