BrainWave Generator File, created with version 3.1  1Frequency-response Calibrationò&ó&BdGŒ%G2GŒ%G2GŒ%G2GŒ%G2GŒ%G2GŒ%G2ÿÿListening to this preset for 3-5 minutes will induce a feeling of tension at a specific region or regions of the body. By changing the main frequency to discrete values between 50 and 200 Hz, a map can be made correlating frequencies to locations along the center-line of one's head. The associated background file, hedmap.jpg, is a JPEG image of such a map, based upon the author's observations. (Needless to say, it is not meant to be incorporated into the preset.) It is commonly believed that the effects associated with binaural entrainment are due solely to the difference between the frequencies of the right- and left-channels and that the values of these carrier frequencies are not significant. This preset supplies evidence that this is not necessarily the case. In addition, consider a binarural preset created by an author for whom an 80 Hz monaural tone stimulates the region where the nose intersects with the eye-line. A listener for whom 80 Hz stimulates the middle of the forehead would probably not observe the same effects for that preset: their respective heads do not react the same. This might explain why one person's 5-star preset has little effect on another. If this is the case, then lists correlating frequency to effect need to be normalized to account for each person's individual harmonics before they can be of general use. In the attached JPEG map, the lines associated with 50 and 60 Hz indicate that these frequencies stimulate not only the bridge of nose, but also the mouth and chin, respectively. The wireframe head in the map is taken from the Poser(R) application by Curious Labs. The 7.5 Hz noise-sweep in the preset is provided for aesthetic and pedagogical reasons; it serves no other apparent function. %…d*' 'ˆ '' èd' 'ˆ '' $ d% ' èd ' $jüÿÿè ˆ ' %…dè è' èdè è' $ dˆ ˆˆ ˆ' èdˆ ˆˆ ˆ' $ d ˆ '  èd ˆ ' $jPÃ@B @Bˆ @B'  èPÃ@B @Bˆ @B' $à.˜þÿÿh ˆ ' $èd ' èd ' %…d/' 'ˆ '' èd' 'ˆ '' %…d/' 'ˆ '' èd' 'ˆ ''  d ˆ ' èd ˆ ' jPÃ@B @Bˆ @B' èPÃ@B @Bˆ @B' à.˜þÿÿh ˆ '  d ˆ ' èd ˆ ' jPÃ@B @Bˆ @B' èPÃ@B @Bˆ @B' à.˜þÿÿh ˆ ' $ d' '' èd' '' $jPÃàpr àpr'  èPÃàpr àpr' $à.˜þÿÿhlîÿÿ lîÿÿ' 1è˜þÿÿh ˆ ' $èüÿÿè ' $Pà N@ @' %è N@ @' $ d*' 'ˆ '' 'èd' 'ˆ '' $ dfô fôˆ fô' )èdfô fôˆ fô' $5РЈ Ð' +èРЈ Ð' $ d' 'ˆ '' -èd' 'ˆ '' $jPà†  †' /èPà†  †' $à.˜þÿÿh ˆ '
