摘要：
This invention relates to a method of performing real ear measurements by a measuring system (100). The measuring system (100) comprises a probe element (1) adapted to be inserted in the ear canal (10) of an individual； a loudspeaker (2, 2') configured to deliver a sample sound signal to the ear canal (10)； at least one microphone (3, 3') configured to detect a response to the sample sound signal, wherein the probe element (1) is in acoustic communication with the loudspeaker (2, 2') and cooperates with the at least one microphone (3, 3')；and a signal processing unit (4) for performing an acoustic measurement of a response to the sample sound signal, based on an electrical input signal from the microphone (3, 3'). The method comprises the steps of a) placing the probe element (1) at a trial distance (dreal) from the tympanic membrane (15)； b) emitting, by the loudspeaker (2, 2'), at least a sample sound signal in the ear canal (10), detecting a response to the sample sound signal by the probe element (1) and measuring, by the signal processing unit (4), the spectrum of the sample sound signal；c) estimating, based on the spectrum measurement, a prediction distance (dpred) of the probe element (1) from the tympanic membrane (15)； d) only if the prediction distance (dpred) is less than a first measuring distance threshold value, providing the information that the probe element (1) is at a target position (ptarget) suitable for performing real ear measurements and performing a real ear measurement. If not, the method comprises the steps of e) determining a correction distance (dcorr) as a function of the prediction distance (dpred)； f) instructing the adjustment, by an operator, of the position of the probe element (1) according to the indication of said correction distance (dcorr), thus reaching a residual distance (dres) of said probe element from the tympanic membrane (15)； g) reiterating steps from b) to f).La présente invention concerne un procédé pour réaliser des
