Abstract: A system response of an individual listener's brain to a sound signal stimulus is estimated. The system response represents the generation of an electroencephalography signal measured at a given measuring point of the listener's head by the sound signal stimulus. A sound signal with the sound signal stimulus is presented to the ear of the listener. An audio signal corresponding to the sound signal is generated, and audio signal data is extracted from the audio signal with a measuring electrode that measures an electroencephalography training signal. A measurement data set is generated from the first electroencephalography training signal. A noise signal is measured on the listener's head while the first sound signal impinges on the listener's ear. A Gaussian conditional probability density function taken as the system response of the listener's brain to the sound signal stimulus, with respect to the given measurement point.

Abstract: The invention relates to a method for obtaining etheric oils and/or constituents of etheric oils from the peel of citrus fruit and/or herbs that have a high residual moisture content comprising the steps a) extraction of the moist extraction material with an extraction agent mixture comprising at least one polar and at least one non-polar solvent for obtaining a miscella, wherein the extraction material is selected from citrus fruit peel and/or residues from the juice production from citrus fruits and/or herbs, wherein the extraction material has a residual moisture content of 5 to 95% by mass, measured on the total mass of the extraction material, wherein the extraction agent mixture contains at least one non-polar solvent in a proportion of 45 to 95% by volume, measured on the total volume of the extraction agent mixture, wherein the extraction agent mixture has a temperature above ambient temperature but below the boiling point of the lowest boiling-point solvent or of the lowest boiling-point azeotrop

Abstract: A method for moist extraction of oil-containing components from coffee beans and/or residues from coffee production, wherein the coffee beans and/or residues from coffee production with a residual moisture content of 10 to 95 percent by mass, measured with reference to the total mass of the coffee beans and/or residues from coffee production are extracted with a mixture of extraction agents consisting of at least one each of a polar and a nonpolar solvent.
