A method of performing real ear measurements by a measuring system, said measuring system comprising: - a probe element adapted to be inserted in the ear canal of an individual; - a loudspeaker (2, 2') configured to deliver a sample sound signal to said ear canal; - at least one microphone (3, 3') configured to detect a response to said sample sound signal, wherein said probe element is in acoustic communication with said loudspeaker (2, 2') and cooperates with said at least one microphone (3, 3'), and - a signal processing unit for performing an acoustic measurement of a response to said sample sound signal, based on an electrical input signal from said microphone (3, 3'), the method aiming at achieving a placement of said probe element at a target position (p target) from a tympanic membrane of an individual's ear canal which is suitable for performing real ear measurements, and comprising the steps of: a) placing said probe element at a trial distance (d read) from said tympanic membrane, b) emitting, by said loudspeaker (2, 2'), at least a sample sound signal in said ear canal, detecting a response to said sample sound signal by said probe element and measuring, by said signal processing unit, the spectrum of said sample sound signal, c) estimating, based on said spectrum measurement, a prediction distance (d pred) of said probe element from said tympanic membrane; d) only if said prediction distance (d pred) is less than a first measuring distance threshold value, providing the information that the probe element is at said target position (p target) and performing a real ear measurement; e) if not, determining a correction distance (d corr) as a function of said prediction distance (d pred); f) instructing the adjustment, by an operator, of the position of said probe element according to the indication of said correction distance (d corr), thus reaching a residual distance (dres) of said probe element from said tympanic membrane, g) reiterating steps b) to f), wherein the step of estimating, by said spectrum measurement, a prediction distance (d pred) of said probe element from said tympanic membrane is based on a statistical probability distribution that said prediction distance (d pred) equals each one of a range of distance values from a tympanic membrane. - a probe element adapted to be inserted in the ear canal of an individual;
