Wireless binaural hearing system

Номер: US20120087505A1
Автор: Jacob Midtgaard, Petar Popovski, Peter S. K. HANSEN
Принадлежит: Oticon AS

A wireless binaural hearing system comprises a left-ear hearing device, a right-ear hearing device and auxiliary devices. The devices communicate via radio signals. Each device comprises a radio transmitter transmitting messages, each hearing device comprises a radio receiver receiving messages, the auxiliary device is adapted to transmit application messages, and the hearing devices are adapted to receive application messages. The quality of wireless communication varies when the user moves his head, which may lead to temporal gaps in communication. Such gaps may cause annoying pauses and/or delays in audio signals presented to the user, and the hearing devices may become temporarily unsynchronised. To avoid such gaps and improve reliability of the communication, without increasing the radio signal power, a first hearing device relays received application messages to a second hearing device in dependence on network messages received from the second hearing device indicating whether application messages were correctly received.

A method and system for automatically configuring a medical device that is at least partially implanted in a human recipient and that includes a transducer arranged to stimulate a physiological system of the recipient, such as a middle-ear implant for instance. The energy level of a signal provided to drive the transducer is progressively increased until there is a threshold electrical change indicative of a threshold change in impedance of the transducer. In the context of a middle-ear implant, for instance, the threshold electrical change indicative of the threshold change in impedance of the transducer may be indicative of the acoustic reflex. The energy level of the signal at that point is then used as a basis to set an operational parameter of the medical device, such as a comfort-level of the middle-ear implant for instance.

Systems and methods may be used to modify a controllable stimulus generated by a digital audio device in communication with a human user. An input signal is provided to the digital audio device. In turn, the digital audio device sends a stimulus based on that input signal to the human user, who takes an action, usually in the form of an output signal, to characterize the stimulus that the user receives, based on the user's perception. An algorithm then determines a difference between the input signal and the output signal, and a perceptual model is constructed based at least in part on the difference. Thereafter, a new value for the parameter of the digital audio device is suggested based at least in part on the perceptual model. This process continues iteratively until the algorithm finds the user's optimal device parameters. While this process is highly complex and time consuming, the algorithm successfully reaches at least a near optimal settings, if not the optimal, in a short time. 1.

Method for Matching a Hearing Apparatus By Percentile Analysis and Matching Apparatus

Номер: US20130208934A1
Автор: Josef Chalupper
Принадлежит: Siemens Medical Instruments Pte Ltd

High-quality adjustment of a hearing apparatus, and in particular of a hearing aid, is accelerated. In the adjusting method, a percentile analysis is carried out in order to obtain at least one frequency response of the hearing apparatus. Any discrepancy between the frequency response and an intended gain characteristic is determined. The setting of the hearing apparatus is then changed, such that the discrepancy is reduced. In order to check the effect of the setting change, a current frequency response after variation of the setting is determined by providing a constant noise signal or a single sinusoidal sweep at the input of the hearing apparatus and level measurement at the output. This frequency response measurement can be carried out as a second step considerably more quickly than the very precise percentile analysis at the start of the process.

Because the external-facing microphones may be situated within the pinna of the ear but outside of the ear canal, the microphones will experience some, but not all, of the three-dimensional acoustic effects of the pinna. In some embodiments, sound is reproduced by an internal-facing driver element of the housing using a plurality of filters applied to the signals received by the plurality of external-facing microphones to preserve three-dimensional localization cues that would be present at the eardrum in the absence of the housing, such that the housing is essentially transparent to the user. In some embodiments, techniques are provided for deriving the plurality of filters. 1.

METHOD AND SYSTEM FOR SELF-MANAGED SOUND ENHANCEMENT

Номер: US20180035216A1
Автор: CHENG Ka Kui, KAM Chi Shan Anna, LEE Pui Tong Paul, VAN HASSELT Charles Andrew
Принадлежит:

A system for capturing an individual's hearing characteristics, including loudness tolerance levels at different sound frequencies, as an individualized shaped auditory profile for automatically enhancing audio to complement and address an individual's hearing deficits experienced via a particular signal pathway including the audio device, the sound environment, and the individual's hearing capabilities. The auditory profile is used to produce enhanced sound subsequently transmitted to the individual via the same signal pathway. The enhanced sound may be produced with consideration of both ears' auditory profile shapes together to increase the dynamic range of the enhanced sound. The sound enhancement can be introduced gradually over a sound reproduction session or a period of time of use. Manual gain adjustments applied by multiple users to particular sound enhancement are recorded and used in pattern recognition to allow the system to learn and suggest alternatives to the desired sound enhancement for the auditory profile. 1. A method for reproducing sound to an individual using modified or enhanced audio signal tailored to audiological characteristics of the individual , comprising:capturing the individual's audio hearing characteristics, including determining the individual's minimum audible level for at least one audiometric frequency;analyzing the individual's hearing characteristics to generate an individualized audiological profile;storing the individualized audiological profile in a storage means;using the individualized audiological profile to determine a first frequency-specific gain adjustment for an input audio signal to compensate for frequency-dependent loudness deficits in the individual's hearing;generating a gradually modified audio signal by applying gradually the first gain adjustment to an input signal; andsound-reproducing from the gradually modified audio signal to the individual using an electronic device that reproduces sound;wherein the ...
