A binaural digital hearing aid system
TLDR
In this article, a binaural digital hearing aid system comprises two hearing aid units (1, 2) for arrangement in a user's left and right ear, respectively, each unit comprises input signal transducer means (3r, 3l), A/D conversion means (4r, 4l), digital signal processing means (5r-13r, 5l-13l), D/A conversion mean (14r, 14l), and output signal transducers means (15r, 15l).Abstract:
A binaural digital hearing aid system comprises two hearing aid units (1, 2) for arrangement in a user's left and right ear, respectively. Each unit comprises input signal transducer means (3r, 3l), A/D conversion means (4r, 4l), digital signal processing means (5r-13r, 5l-13l), D/A conversion means (14r, 14l) and output signal transducer means (15r, 15l). A bi-directional communication link (7) is provided between the units. The digital signal processing means of each unit is arranged to affect a substantially full digital signal processing including individual processing of signals from the input transducer means of the actual unit and simulated processing of signals from the input transducer means of the other unit as well as binaural signal processing and includes at least a first digital signal processor part (5r, 5l) for processing said internally supplied signal, a second digital signal processor part (6l, 6r) for processing the signal supplied via said communication link (7) and a third digital signal processor part (9r, 9l) to effect common binaural digital signal processing of information derived from the signals processed in said first and second digital signal processor parts, said second digital signal processor part (6l, 6r) in each unit simulating the first digital signal processor part (5l, 5r) in the other unit with respect to adjustment parameters controlling the performance of said first signal processor part in said other unit.read more

At least partially implantable system for rehabilitation of a hearing disorder
TL;DR: An at least partially implantable system for rehabilitation of a hearing disorder with at least one acoustic sensor (microphone) for picking up an acoustic sensor signal and converting it into corresponding electrical signals, an electronic signal processing unit for audio signal processing and amplification, an electrical power supply unit which supplies individual components of the system with energy as mentioned in this paper.
Patent
Hearing aid wireless network
TL;DR: In this paper, a hearing aid includes a transceiver for interconnection of the hearing aid with a wireless network, and a communication controller that is adapted for controlling data exchange through the network in accordance with a network protocol, wherein the controller is further adapted for initialisation of the network by controlling the transceiver to transmit interrogation data repetitively, and upon receiving an interrogation data received message from another device, in a connected mode acting as a master of the wireless network by repetitively transmitting synchronization data at intervals that are longer than the intervals between transmitted interrogation data in the acquisition mode.
