Beschreibung
Zusammenfassung:	The invention relates to an intra-aural hearing aid for the deaf or hard of hearing with an earpiece which contains a microphone, an amplifier, an earphone, a battery compartment with battery and a balancing channel leading from the inside to the outside, closed off by a cover plate. The balancing channel (2, 2A) partially or completely surrounds at least a part of the sound outlet channel (4) from the earphone (5). This section (2A) is joined by another (2B) which continues past the earphone (5) towards the cover plate (3) and is at least partially an integral component of a unit (6) containing the earphone (5) and at the same time forms the transition between the two sections (2A, 2B) of the balancing channel.
