METHOD AND SYSTEM FOR TESTING A MOULD SHAPE QUALITY OF A USER-CUSTOMIZED EAR MOULD

摘要

The present disclosure concerns a method for determining a mould shape quality (Q) of an ear mould (2) customized to an ear canal (31) of a user by means of a mould testing system (100). The mould testing system (100) comprises an acoustic generator (3) and a microphone (4) arranged in a test housing (1) with an open end (1c) that is connectable to an inner passage (2c) of the custom ear mould (2). The method comprises inserting the ear mould (2) into the ear canal (31); connecting the test housing (1) to the ear mould (2); generating an acoustic signal (Sg) into the ear canal (31) via the inner passage (2c); measuring the acoustic signal (Sr) from the ear canal (31); comparing the measured signal (Sm) with a reference signal (Se); and providing a feedback signal (Sf) based on the said comparison. The feedback signal (Sf) is a measure for the mould shape quality (Q) of the custom ear mould (2).
