摘要： 5 n 7 An in the ear (I.T.E.) hearing aid is formed by an ogival body (1) which is meant to be removably inserted into the acoustic meatus of the external ear, and inside the ogival body (1) there being accomodated a microphone (2) comunicating (3) with the external enviroment; an amplifier (4) being connected to the microphone (2); an electric-acoustic transducer (5), so called receiver, connected to the output of the amplifier (4) and comunicating with the duct (401, 501) having one opening at the internal end of the ogival body (1); and a housing for one or more piles or batteries for the hearing aid electric feeding. According to the invention, the electric-acoustic transducer (5) comunicates with a branched duct (501) branched off a longitudinal through duct (401) with its one end debouching at the external end of the ogival body (1) and with its other end debouching at the internal end thereof, which ducts are so provided that any cerumen and any further possibly occurring liquid secretions of the ear are not allowed to get into the branched duct (501) or reach the electric-acoustic transducer (5).
