发明名称	Ermittlung von Daten über das Hörvermögen
摘要	The invention relates to a process for obtaining data on hearing capacity by measuring distortion products of otoacoustic emissions (DPOAE), in which two primary tones with the frequencies f1 and f2 > f1 and sound pressure levels L1 and L2 and at least one sound with proportions of the frequency f3 and the sound pressure level L3 are applied as stimuli to the hearing organ and at least one distortion product of defined frequency is determined, where the value of f3 is close to the frequency of the distortion product.
