For this purpose, the setting of an operating ... 10/25/07 - 20070248237 - Integrated automatic telephone switch Methods and apparatus for a hearing aid include a mechanism to detect the presence of a magnetic field using a magnetic sensing device disposed in a hearing aid, to digitally modify a frequency response of the hearing aid in response to the detection of the presence, and to modify the ... 07/12/07 - 20070160243 - System and method for separation of a user's voice from ambient sound A system for separation of a user's voice from ambient sound, comprising a device to be worn at the user's ear or at least partly in the user's ear canal comprising a first microphone oriented acoustically outwardly towards the environment and a second microphone oriented acoustically inwardly towards the user's ... 03/15/07 - 20070058828 - Hearing aid A technique is disclosed, which can shorten attack time and release time without using RC filter with time constant. According to this technique, diodes 51 and 52 rectify AC signal at output stage of an amplifier 30 by voltage doubler rectification, and a smoothing capacitor 53 smoothens the signals rectified ... 02/08/07 - 20070030989 - Hearing aid with suppression of wind noise The present application relates to a hearing aid with suppression of wind noise wherein wind noise detection is provided involving only a single comparison of the input signal power level at first low frequencies with the input signal power level at frequencies that may include the first low frequencies whereby ... 01/11/07 - 20070009127 - Hearing aid with reduced wind sensitivity and corresponding method The wind sensitivity of hearing aids is to be further reduced. It is therefore proposed to measure a noise level of at least two microphones and to compare the levels with one another. The microphones are then controlled according to the comparison result. Preferably the microphone having the lowest noise ... 10/19/06 - 20060233407 - Hearing device and method for wind noise suppression To reduce the disturbing effect of artifacts created by signal processing when reducing wind noises the microphone signal of a hearing device for the presence or the strength of a predefined wind noise signal and, if appropriate, the wind noise signal is released. A noise signal is generated that is ... 10/12/06 - 20060227988 - Digital communication device A digital communication device such as a hearing aid or a headset has a power supply, a signal processing device, means for receiving a wireless signal and a receiver or loudspeaker which produces an audio signal based on a modulated pulsed signal with high frequency shifting rate produced by the ... 09/14/06 - 20060204025 - Hearing aid and a method of processing signals A hearing aid (30) comprises a microphone (71), a signal processing means (20) and an output transducer (22), and the signal processing means (20) comprises a set of audio processing parameters mapped to a set of stored noise classes (12) and means (8) for classifying the background noise for the ... 07/06/06 - 20060147070 - Device for protecting the hearing from loud mrt sounds Device for protecting the hearing from loud MRT sounds Device for protecting the hearing from loud MRT sounds, with a protective sound generating device linked to the MRT electronics for generating a protective sound rising slowly in amplitude, increasing the impedance in the middle ear immediately before the onset of ... 06/29/06 - 20060140429 - Heating aid with acoustic feedback suppression A hearing aid having an input transducer (2), a signal processor (3), an output transducer (4) and an adaptive filter (5) for generating a feedback cancellation signal (101) further comprises a norm estimator (10) generating a first norm signal (109) indicative of a norm of the electrical input signal and ... 05/18/06 - 20060104465 - Method for detection of ultrasound in a listening device with two or more microphones, and listening device with two or more microphones The invention concerns a method for detecting and minimizing the harmful influence of ultra sound in a listening device having two or more microphones. The energy contents in the microphone signals is determined, and time related changes in energy contents of the microphone signals is analysed to determine whether any ... 05/04/06 - 20060093174 - Hearing aid It is intended with a hearing aid that an electromagnetic interference field generated in the hearing aid device itself and acting on a transmit and/or receive antenna (7) should be attenuated or compensated for in a simple fashion. It is proposed to this end that the supply lines (6C, 6D) ... 05/04/06 - 20060093173 - Method and signal processor for reducing feedback in an audio system Feedback in audio systems and particularly in hearing aids needs to be detected more reliably, so that it can be filtered as appropriate. For this purpose, the invention provides for the output signal from a signal processing section is modified using a modulation unit to produce a modulated output signal. ... 02/02/06 - 20060023907 - Power-saving mode for hearing aids Hearing aid wearers can find themselves in situations in which the necessary replacement and/or recharging of a discharged voltage source is not immediately possible. In such a situation, reducing the low-frequency signal elements in the acoustic output signal allows a type of emergency mode to be maintained for a certain ... 10/20/05 - 20050232452 - Digital hearing aid system A digital hearing aid is provided that includes front and rear microphones, a sound processor, and a speaker. Embodiments of the digital hearing aid include an occlusion subsystem, and a directional processor and headroom expander. The front microphone receives a front microphone acoustical signal and generates a front microphone analog ... 08/11/05 - 20050175202 - Telephone with integrated hearing aid An integrated telephone and hearing aid that has a single in-ear speaker is disclosed. The illustrative embodiments automatically adapt the operation of the hearing aid based on whether a telephone call is in progress or not. For example, when the user is not engaged in a telephone call, the illustrative ... ### FreshPatents.com Support |
