    摘要: This invention relates to a hearing device for compensating hearing impairment of a user. The hearing device comprises an input signal converter for converting an acoustic signal to an electric signal, a signal processor, an output signal converter for converting a processed signal to a processed acoustic signal presented to the user, and an adaptive feedback suppression unit compensating for acoustic feedback between the output signal converter and the input signal converter and to generate a feedback compensation signal, which is mixed with the electric signal from the input signal converter to provide a compensated electric signal. The signal processor is adapted to process the compensated electric signal and to generate a processed signal therefrom. The hearing device further comprises an open loop approximation unit adapted to monitor relation between the compensated electric signal and the processed signal, and adapted to generate a control signal based on the relation, the control signal controlling the signal processor and/or the adaptive feedback suppression unit.

    摘要: A method and an audio processing system determine a system parameter, e.g. step size, in an adaptive algorithm, e.g. an adaptive feedback cancellation algorithm so as to provide an alternative scheme for feedback estimation in a multi-microphone audio processing system. A feedback part of the system's open loop transfer function is estimated and separated in a transient part and a steady state part, which can be used to control the adaptation rate of the adaptive feedback cancellation algorithm by adjusting the system parameter, e.g. step size parameter, of the algorithm when desired system properties, such as a steady state value or a convergence rate of the feedback, are given/desired. The method can be used for different adaptation algorithms such as LMS, NLMS, RLS, etc. in hearing aids, headsets, handsfree telephone systems, teleconferencing systems, public address systems, etc.

    摘要: The invention relates to a hearing aid system comprising first and second spatially separated hearing instruments, the system being adapted for processing input sounds to output sounds according to a user's needs. The invention further relates to a method and use. The object of the present invention is to provide an alternative scheme for reducing the effect of acoustic feedback in a hearing aid system. The problem is solved in that the hearing instruments comprises, respectively, first and second input transducers for converting a first input sound to first and second electric input signal, and first and second output transducers for converting first and second processed electric output signal to first and second output sounds, wherein the system is adapted to provide that a first Tx-signal originating from the first electric input signal of the first hearing instrument is transmitted to the second hearing instrument and used in the formation of the second processed electric output signal, and that a second Tx-signal originating from the second electric input signal of the second hearing instrument is transmitted to the first hearing instrument and used in the formation of the first processed electric output signal. This has the advantage of providing a scheme for reducing or effectively eliminating acoustic feedback in a pair of hearing instruments. The invention may e.g. be used in listening devices, e.g. hearing aids, head sets, or active ear plugs.

    摘要: Systems and methods for keyword based searching in a database are described herein. In one implementation, the method comprises receiving a keyword based query, comprising at least one keyword, from a user. The method further comprises searching an inverted index associated with the database to detect the presence of at least one of the keywords in documents, identified by a document ID, present in the inverted index. Based on the searching, the documents in which at least one of the keywords is present are identified. The identified documents are then ranked in a descending order of relevancy.
