An electronic translator translates input speech into multiple streams of data that are simultaneously delivered to the user, such as a hearing impaired individual. Preferably, the data is delivered in audible, visual and text formats. These multiple data streams are delivered to the hearing-impaired individual in a synchronized fashion, thereby creating a cognitive response. Preferably, the system of the present invention converts the input speech to a text format, and then translates the text to any of three other forms, including sign language, animation and computer generated speech. The sign language and animation translations are preferably implemented by using the medium of digital movies in which videos of a person signing words, phrase and finger spelled words, and of animations corresponding to the words, are selectively accessed from databases and displayed. Additionally the received speech is converted to computer-generated speech for input to various hearing enhancement devices used by the deaf or hearing-impaired, such as cochlear implants and hearing aids, or other output devices such as speakers, etc. The data streams are synchronized utilizing a high-speed personal computer to facilitate sufficiently fast processing that the text, video signing and audible streams can be generated simultaneously in real time. Once synchronized the data streams are presented to the subject concurrently in a method that allows the process of mental comprehension to occur. The electronic translator can also be interfaced to other communications devices, such as telephones. Preferably, the hearing-impaired person is also able to use the system's keyboard or mouse to converse or respond.

A disposable-type hearing aid uses a relatively large single diaphragm or a large single diaphragm subdivided into a plurality of smaller active diaphragm areas obtained using a grate-like back support plate with ridges which contact and divide the diaphragm into the several smaller active diaphragm areas. The diaphragm and a backplate are enclosed in a metal housing and are disposed proximal and parallel to a shell-like hearing aid enclosure having sound inlets. The metal housing is closed at an end opposite the sound inlets by a printed circuit board (PCB) forming an acoustical seal for a back volume of the microphone. The PCB also carries substantially all the electronic components for the hearing aid thereon. The PCB has a ground plane in contact with the housing whereby the PCB also acts as an EMI shield. An electrical connection is formed in various ways between the back support plate and the PCB during assembly of the metal housing and components with the PCB. Mass production of disposable hearing aids with large diaphragms and relatively low noise levels is thus possible using this invention.

A mechanism for detachably mounting an earpiece having a receiver and an acoustic tube to any one of a variety of hearing aids includes using an adhesive and a clip attached to the acoustic tube to adhere the clip and thus the earpiece to a surface of the hearing aid, so that an open end of the acoustic tube is near an acoustic aperture of the hearing aid and can thus provide an acoustic sound signal to a microphone within the hearing aid. Alternatively, the clip can be provided with a magnet and a ferric plate can be fixed to a surface of the hearing aid, so that magnetic forces between the magnet and the ferric plate will attach the earpiece and the hearing aid together. The magnet and the ferric plate can be chosen so that the earpiece will separate from the hearing aid when a relative force between the earpiece and the hearing aid exceeds a predetermined threshold, thus preventing injury to a user wearing the hearing aid and the earpiece.

The range for transmission of signals between hearing aids is to be improved. To this end it is proposed that signals be transmitted between a first hearing aid worn by a first hearing aid wearer and a second hearing aid worn by a second hearing aid wearer. In this case the transmitted signals can consist of control parameters, sound field characteristic values or an audio signal.

The third hearing aid fulfills the function of a relay station in this case. Through the invention a signal with improved signal-to-noise ratio can be fed directly to the hearing of a hearing aid wearer or the signal processing of a hearing aid can be better adapted to the relevant environmental situation.
