Abstract: At least one exemplary embodiment is directed to an in-the-ear-canal device comprising: an insertion element; and at least one non-circumferential protrusion, where the at least one non-circumferential protrusion is operatively connected to a surface of the insertion element and provides a stabilizing force for maintaining the position of the insertion element in an ear canal.

Abstract: For providing protection against penetration of fluid-like substances within the ear canal of a hearing aid user into the hearing aid sound port, a hood-like member is utilized in surrounding relation with the sound port for providing paths for the fluid-like substances past and spaced apart from the sound port. The hood-like member is disposed at the end of a hollow stem which provides means for mounting the hood-like members on the hearing aid; the stem either being inserted into the hearing aid sound port, or the hearing aid output sound tube extending into the hollow stem.

Abstract: An otherwise conventional in-canal hearing aid, including a receiver providing a sound output port typically facing directly towards the ear drum of a user, is provided with a hood disposed between the sound port and the ear drum completely shielding the sound port from foreign substances moving towards the hearing aid from all directions except upwardly from the bottom floor of the user's ear canal. The hood can comprise solid vertical walls completely surrounding the sound port and forming a downwardly extending sound conduit terminating in a downwardly facing sound exit, or the vertical walls can comprise a mesh preferably also forming a downwardly facing sound conduit and sound exit. The hoods provide gravity assisted paths, particularly for mobile fluid components of the foreign substances, downwardly past and away from the receiver sound port. The hoods can be extensions of the hearing aid receiver at the front end of the receiver.

Abstract: A resonant earmold for amplifying selected frequencies of the sound signal introduced into the earmold. The path for sound through the earmold includes transversely disposed, off-axis elongated chamber sections (24,25), the various sections functioning as a single acoustic chamber. Interchangeable inserts (30,50) of different dimensions are used, on a trial and error basis, for changing the dimensions of at least one of the sections for fine tuning the sound characteristics of the earmold to best match the hearing aid performance characteristics with the needs of the user.
