Abstract: In a method and system for fitting the gain of a hearing aid (300) for a hearing impaired person, a loop gain of the hearing aid in the ear canal (350) of the hearing impaired person is measured for at least one frequency band. An effective vent parameter such as a corresponding vent diameter for the hearing aid by determining a vent parameter that generates the best fit between a modelled and the measured loop gain is estimated, a vent effect value based on the estimated effective vent parameter is determined, and a corrected hearing aid gain is provided by means of the determined vent effect value. The invention provides a method, a computer program, a system for fitting a hearing aid, a hearing aid and a computer system.

Abstract: For the protection of an in-the-ear hearing aid against contamination by ear wax through the acoustic outlet port (34a) or a vent, a replaceable ear wax guard (36) is inserted in the aid and includes an essentially tubular element with a through-going cavity and an abutment collar in one end for sealing abutment against the hearing aid housing (31). For an easy and safe insertion and removal of the ear wax guard (36), an applicator is used, which in one end has a smooth pin for introduction in the through-going cavity of the ear wax guard (36) and in the other end a harpoon-shaped catch member. For mounting of the ear wax guard (36) a hose or tube member serving as acoustic outlet canal (34) is connected to an abutment collar (33) in abutment with the outside of hearing aid. The abutment collar is designed with oversize standard dimensions and adapted to an individually user-adapted hearing aid housing by preparation of its periphery edge.

Abstract: An earplug for a hearing aid adapted for engagement with earpieces made of materials with a comparatively high hardness. The earplug comprises a resilient sleeve and a shell, the shell having an outer portion adapted to fit within a user's ear canal and a central bore, the central bore having a first abutment shoulder adapted for retaining the resilient sleeve inside the shell and a second abutment shoulder adapted for providing a stop for the resilient sleeve and for the earpiece. Hereby the resilient sleeve is able to combine relatively relaxed manufacturing tolerances with precise positioning of the earpiece inside the earplug.

Abstract: The present invention relates to manufacturing of a hearing aid housing comprising a face plate and a shell that is individually matched to the shape of the auditory canal of a user. Manufacture of the face plate includes at least one automatic processing step based on data from a CAD/CAM model of the hearing aid housing. For example, data relating to the circumference of the face plate may be provided to a numerically controlled machine that automatically cuts a separately manufactured face plate along the desired contour that matches the circumference of the corresponding shell. In another embodiment, the hearing aid housing is manufactured with an integrated face plate.

Abstract: A combination unit for attachment to a hearing aid includes an adapter and an accessory, having mating guideways, respective assembly pressure faces (14,29) adjacent the guideways and respective disassembly pressure faces (13, 30), also adjacent on the guideways. The adapter (2) includes a shoe, i.e. a sleeve-like structure, adapted to partially enclose the lower portion of the hearing aid. The accessory (3) may include a miniature FM receiver. The receiver housing (22) exterior is tailored to match the adapter exterior in order that the respective walls are flush when the parts are assembled. The combination unit (1) of the adapter and the accessory is easily assembled and easily disassembled, and is very compact. The invention provides a combination unit, including the shoe and the accessory, as well as a method for attaching an accessory to a hearing aid.

Abstract: For the protection of an in-the-ear hearing aid against contamination by ear wax through the acoustic outlet port (34a) or a vent, a replaceable ear wax guard (36) is inserted in the aid and includes an essentially tubular element with a through-going cavity and an abutment collar in one end for sealing abutment against the hearing aid housing (31). For an easy and safe insertion and removal of the ear wax guard (36), an applicator is used, which in one end has a smooth pin for introduction in the through-going cavity of the ear wax guard (36) and in the other end a harpoon-shaped catch member. For mounting of the ear wax guard (36) a hose or tube member serving as acoustic outlet canal (34) is connected to an abutment collar (33) in abutment with the outside of hearing aid. The abutment collar is designed with oversize standard dimensions and adapted to an individually user-adapted hearing aid housing by preparation of its periphery edge.

Abstract: A tool (20) and a method for shaping an elongated deformable member for a hearing aid (1). The tool is manufactured using a rapid prototyping process. The tool comprises a first holding means (21) for a first end of the elongated member, a second holding means (31) for holding a second end of the elongated member, and positioning means (26,28) for positioning and holding intermediate parts of said elongated member between said first end and said second end in a fixed desired shape. The shaping a of the deformable elongated member comprises the steps of placing the first end of the elongated member in a predetermined position, positioning said intermediate parts of said elongated member in a predetermined position, placing the second end of the elongated member in a predetermined position, heating said elongated member, and cooling said elongated member.
