Abstract (en)
[origin: EP0325107A1] The method uses a porous elastic moulded part (15,15'), for example a foam material, and a curable material (21,21'), for example resin, in order to produce an ear mould (28) which is particularly accurately matched to the ear. The moulded part (15,15') is saturated or coated with the curable material (21,21') and then inserted into the ear of the person with defective hearing, where it cures after about 10 minutes. The direct production of the ear mould in the auditory canal (25) of the person with defective hearing is particularly advantageous; the earlier additional production of an imprint and of a negative can be omitted in the method according to the invention. <IMAGE>
