A METHOD OF PERFORMING REAL EAR MEASUREMENTS BY PLACING A PROBE ELEMENT AT AN INTENDED POSITION FROM A TYMPANIC MEMBRANE OF AN INDIVIDUALS EAR CANAL AND A MEASURING SYSTEM CONFIGURED TO CARRY OUT SUCH METHOD.
The present invention relates to a kind of methods that the real ear for executing through a measuring system (100) measures. Measuring system (100) includes the probe element (1) for being adapted for inserting into the ear canal (10) of an individual One loudspeaker (2,2) is configured to this voice signal as being delivered to ear canal (10) At least one microphone (3,3) is configured to detect the response to sample audio signal, and wherein probe element (1) is in the acoustic communication with loudspeaker (2,2) and cooperates at least one microphone (3,3) For executing a signal processing unit (4) signal of the acoustic measurement of the response of sample audio, an electrical input signal is based on from microphone (3,3). The method comprising the steps of: in a test distance (dreal) a for coming from eardrum (15)) place probe element (1) B) this voice signal as at least in ear canal (10) is issued with loudspeaker (2,2), detection passes through probe element (1) and the response to sample audio signal measured, by signal processing unit (4), various sample audio signals C) estimate, be based on spectrum measurement, a predicting interval (dpred) for the probe element (1) from eardrum (15) D) only when the predicting interval (dpred) less than first measurement distance threshold when, provide probe element (1) be adapted for carrying out real ear measure and execute real ear measure a target position (ptarget) information. Otherwise, method includes the following steps: e), the function as the predicting interval (dpred), which determines, changes positive distance (dcorr) F) guidance adjustment, by an operator, instruction of the position of probe element (1) according to the correction apart from (dcorr), to reach a remaining distance (dres) of the glycogen element from eardrum (15) G) reaffirm step from b) to f).
