Abstract: Hearing apparatuses should be manufactured as simply as possible and with the closest possible fit. Accordingly, a molding structure is provided, which represents a model for the direct shaping of an otoplastic of a hearing apparatus. The molding structure has a sealing element, which can be positioned in the auditory canal. A molding mass is inserted into the auditory canal to a side of the sealing element facing the outlet of the auditory canal. The molding mass and the sealing element here are connected to form the model of the hearing apparatus and the sealing element has the exact shape of a part of the hearing apparatus.

Abstract: A hearing device has a housing, in which a loudspeaker and a battery are disposed. The housing has a first housing part and a second housing part. The housing parts are connected to one another by way of a connection. At least one housing part or an attenuation element provided in the connection between the housing parts is formed of an elastic material.

Abstract: An acoustic actuator includes a support layer, in which a self-supporting structure is defined and connected to the support layer by at least two suspensions, at least one magnetostrictive layer which has been disposed on the support layer and is provided at least in part on the self-supporting structure, and a device for generating a magnetic field in the magnetostrictive layer. The way in which the loudspeaker works is based on the magnetostrictive effect, which results in a change in the dimensions of the self-supporting structure in an alternating magnetic field. This causes the self-supporting structure to oscillate. A method for producing an acoustic actuator is also provided.

Abstract: In hearing devices, more particularly in hearing aids, it is desirable to be able to design an earpiece for generating sound in the audible range which is as small as possible. Such an earpiece can then be worn comfortably on an ear or in an auditory canal. A sound transducer for the hearing device disclosed here may be formed as a micro-electromechanical system and the transducer enables generation of an acoustic signal with little distortion. Provision is made for a hearing device with a sound transducer, which has a field generation apparatus for generating an electric or magnetic field and an emission apparatus for generating sound. Here, the emission apparatus has a multiplicity of fingers that are penetrated by the field of the field generation apparatus, wherein the shape of the fingers can be changed by means of the field of the field generation apparatus in order to generate the sound.

Abstract: The invention relates to a water-resistant hearing device, which has the following: At least one first electroacoustic transducer for receiving sound waves and converting said sound waves into electrical signals, an electronic circuit sealed against liquids by coating and/or encapsulation, at least one second electroacoustic transducer converting electrical signals supplied to the circuit into sound waves and an electrical energy source sealed against liquids by means of coating and/or encapsulation. In this way the electroacoustic transducers are made of materials which realize a deformation in an electrical and/or magnetic field and/or an electrical current flow and/or an electrical voltage (and/or vice versa) and are insensitive to liquids, in particular water, salt water and slight acids.

Abstract: If a hearing device user has become accustomed to the tone of a hearing device, it is difficult for him to change over to a new hearing device, since this normally possesses a different tone. Therefore, given a treatment with a second or subsequent device, the settings of the old hearing device can be acquired with a computer-controlled event and be considered in a first adjustment given the adaptation of the new hearing device. The new setting then results from the audiometric measurements, the data of the previous device, and if necessary further data. The tone of the new device is thus approximated to the old device.

Abstract: In a hearing device with multiple microphones, and a signal generation method, the dynamic range of hearing devices is improved by using a combination including a silicon microphone and an electret microphone for the hearing device input. Low frequencies thus can be acquired by the silicon microphone and high frequencies can be acquired by the electret microphone, in order to generate a wide-band hearing device input signal. The fact that a silicon microphone possesses a lower internal noise than a conventional electret microphone at low frequencies is utilized.

Abstract: An acoustic module for a hearing aid device has at least one microphone and at least one earphone (acoustic output transducer) combined together as a unit, the unit including a signal-processing unit for feedback suppression that is connected with the microphone and the earphone. Feedback signal portions are removed from the microphone signal by the signal-processing unit. The acoustic module places acousto-mechanical components within a unitary component, with acousto-mechanical characteristics that can be measured and included in the signal processing for feedback suppression.

Abstract: The process of adapting a hearing aid to its wearer is to be simplified. To this end the acoustic conditions in the auditory canal, especially the acoustic impedance, are estimated by measuring the input impedance of the earpiece on the hearing aid. For adjusting the hearing aid it is worthwhile using the mechanical resonance of the system of hearing aid and auditory canal which can be detected with the aid of the input impedance. This is produced by a simplified equivalent circuit diagram from which the corresponding acoustic variables can be obtained.

Abstract: The space in hearing device housings (1, 2) is to be enabled to be used more intensively. To this end, the invention pro-poses dispensing with a separate microphone housing and embodying said housing in one piece with the hearing device housing. To reduce the microphone's sensitivity to body sound the corresponding attenuation can be provided in the hearing device shells or the non body-sound-sensitive Silicon microphones (5).

Abstract: An antenna coil is present in a hearing aid device to wirelessly transmit signals between a hearing aid device and a further device. Due to the required miniaturization of hearing aid devices, only minimal space is available for the arrangement of the antenna coil in the hearing aid device. The invention therefore provides for winding the antenna coil around or on an existing electro-acoustic transducer in the hearing aid device or around a capsule surrounding the transducer. A comparatively large antenna coil, for which little additional space is required, can thereby be provided in the hearing aid device.
