Ik kwam na wat zoeken in een ander onderwerp hier terecht:
http://www.google.com/patents/US6470214En was toch behoorlijk verbaasd over wat ik vond, eerst dacht ik nog dat het om telecommunicatie tussen vliegtuigen ging maar uiteindelijk kwam het heel ergens anders terecht, en dat terwijl ik enkel op signaal methode van mobiele telefoons zocht.

With reference to the drawings, FIG. 1 illustrates the RF to acoustic demodulation process of the invention. Ordinarily and acoustic signal A reaches the outer ear E of the head H and traverses first to the inner ear I and then to the acoustic receptors of the brain B. A modulated RF signal, however, enters a demodulator D, which is illustratively provided by the mass M of the brain, and is approximated, as shown in FIG. 2, by a sphere S of radius r in the head H. The radius r of the sphere S is about 7 cm to make the sphere S equivalent to about the volume of the brain B. It will be appreciated that where the demodulator D, which can be an external component, is not employed with the acoustic receptors of the brain B, it can have other forms.
The sphere S, or its equivalent ellipsoid or similar solid, absorbs RF power which causes an increase in temperature that in turn causes an expansion and contraction which results in an acoustic wave. As a first approximation, it is assumed that the RF power is absorbed uniformly in the brain. Where the demodulator D is external to the brain B, the medium and/or RF carrier frequency can be selected to assure sufficiently uniform absorption.
For the modulated RF signal of FIG. 1, the power absorbed in the sphere S is proportional to the power waveform of the modulated RF signal. The absorption rate is characterized quantitatively in terms of the SAR (Specific Absorption Rate) in the units of absorbed watts per kilogram per incident watt per square centimeter.
The temperature of the sphere S is taken as following the integrated heat input from the power waveform, i.e. the process is approximated as being adiabatic, at least for short term intervals on the order of a few minutes.
The radial expansion of the sphere follows temperature and is converted to sound pressure, p(t), determined by the radial velocity (Ur) multiplied by the real part of the specific acoustic impedance (Zs) of the sphere, as indicated in equation (1), below.

Nu ben ik ook al bekend met vibratie commercials en gefocussed geluid (met zo'n plaat waarmee je geluid van een afstand exact op één persoon kunt afvuren zodat mensen om die persoon heen het niet horen maar het target wel)
http://www.eetimes.com/author.asp?section_id=1&doc_id=1283418http://motherboard.vice.c(...)ctly-into-your-skullEn heb ook ooit iets gezien over dat dit toegepast werd als een advertisement stunt in het openbaar, buiten op straat.
Ik weet niet in hoeverre dit hieronder valt.. Maar dat je met een microwave signaal mensen dingen kunt laten horen, laat ik even aanhalen dat dat niet onder geluid valt.. is toch wel verontrustend te noemen.
Vraag yvonne maar hoe tof ik ben, die gaf mij er ooit een tagje voor.
