The following are signal details suggested to those interested in experimenting in voice-to-skull radio transmission or with bioeffects of microwaves in general. The owner of this web page has not yet succeeded in any of these areas, but the information here has been suggested by both rigorous and non- rigorous articles on the subject.

    FOLLOWING ARE BRIEF EXCERPTS FROM OR SUMMATIONS
    FROM ARTICLES SPECIFIC TO VOICE-TO-SKULL TECHNOLOGY
    AS IT RELATES TO THE WRIGHT-PATTERSON SCARE-BIRDS-
    AWAY-FROM-RUNWAYS TECHNOLOGY:

    Science, vol. 181, 27 July 73, Allan H. Frey and
    Rodman Messenger, Jr.:

        p. 356: Perception occurred when the subject
        was illuminated with energy from approximately
        that portion of the EM spectrum defined as the
        UHF band, that is, from 0.3 to 3 GHz.

        p. 357: An approximate threshhold for perception,
        when the subject was in a noisy environment,
        occured at a peak power density of 267 milliwatts
        per square centimeter...

        p. 358: There are also RF modulation parameters
        that cause subjects to report hearing "sounds"
        with definite pitch and timbre characteristics.

    Ottawa, Canada AND,
    Nature, vol. 216, DEC 16 1967, page 1139:

        ** These excerpts deals with microwave-induced
        muscle-jerks, rather than voice-to-skull:

        p. 636: With the antenna mounted vertically
        above the cage, it was observed, a few seconds
        after the onset of radiation [16 GHz, 8,000
        pulses per second, 10 to 30 milliwatts per cm2]
        that sustained extensor activity of a wind and
        leg occurred - a reaction possibly due to the
        penatration of induced electrical activity
        to the spinal cord.  Shielding first the head
        of the chicken, and then the body leaving the
        head exposed, produced no significant change
        in the manifested extensor activity.

        [JIBES WITH MY EXPERIENCE PERFECTLY-E.W.]

    Journal Acoustical Society of America, June 1982,
    Chung-Kwang Chou, Arthur W. Guy, and Robert Galambos:

        [This article is a detailed "proof" that the
        "microwave hearing" phenomenon is thermal in
        nature.  The calculated temperature rise due
        to the pulses studied is a surprisingly small
        1/100,000th to 1/1,000,000th of a degree
        centigrade. - E. W.]

        p. 1321: ...the absorption [of microwave
        energy] can be appreciable at the resonant
        frequency near 70-80 MHz (where the long
        dimension of the [human] body is approx-
        imately 0.4 wavelengths.  For a human head,
        the resonant frequency is near 600 MHz.

        p. 1324: [Describes audio frequencies applied
        as pulse repetition rates - roughly speaking,
        rep rates from 1,000 to 12,000 per second
        were tested and produced various sounds.
        The suggested pulse durations were in the
        range of 5 microseconds to 150 microseconds
        - E.W.]

        pp 1324-1325: In summary, there is uniform
        agreement that human beings with normal high-
        frequency hearing can perceive an auditory
        sensation when exposed to microwave pulses
        of sufficient energy content.  The [UN-
        modulated] RF sound may be perceived as
        clicks, buzzes, or hisses depending on the
        [pulse repetition rate and duration]. This
        received sound, at least for pulses less
        than or equal to 50 microseconds seems to
        originate at the central, posterior aspect
        [i.e. back] of the head.

    Bioelectromagnetics conference, 1992, 13:323-328:

        [This article deals with modification of the
        ability for a sudden sound to startle rats,
        and does not deal with microwave hearing.
        - E. W.]
