Abstract: The invention relates to a method and corresponding system for real-time simulation of N moving or stationary sound sources in a space surrounding a listener, which method processes N input signals, each of which represents one of the N sound sources, thereby obtaining one or more output signals (10, 66, 92, 93) for a listening device, such as a left output signal (yL(t)) and a right output signal (yR(t)) for a stereophonic headphone (98, 99) or the like, which method comprises using solely a single set of fixed filters (57, 58, 59, 60) to simulate all of said N moving or stationary sound sources. The method and system of the invention provide an efficient method for creating many simultaneous sound sources relative to a listener using very low signal processing power.

Abstract: A binaural hearing system comprising left and right hearing devices is provided, each comprising an input unit providing an electric input signal representing an environmental sound; a noise reduction system for estimating and reducing a noise component of the electric input signal; antenna and transceiver circuitry allowing the exchange of data between the hearing devices. The binaural hearing system is—in a mode of operation, where a sound source is predominantly audible at a first one of the hearing devices—configured to transmit the estimate of the noise component determined in a second one of the hearing devices to the first hearing device and to use said estimate to reduce the noise component in the electric signal of the first hearing device and to provide a noise reduced signal in the first hearing device. Thereby improved noise reduction is provided for use, e.g. in hearing aids, in non-symmetric acoustic situations.

Abstract: The application relates to a method of reproducing an acoustical sound field to a listener at a first location, to a method of testing a hearing assistance system, and to a hearing assistance test system. The method comprises 1) Determining a transfer function from each loudspeaker unit of the loudspeaker array to all microphone units of the microphone array, thereby providing a set of transfer functions; 2) Inverting the set of transfer functions and determining a system of optimal filters; 3) Placing the microphone array in a possible, intended position of the listener's head in a particular sound scene at a second location and recording sound of the particular sound scene at the second location; 4) Determining the loudspeaker signals of the particular sound scene configured to be played to the listener at the first location by the loudspeaker array by convolving the inverted system of optimal filters with the recorded signals.

Abstract: The invention relates to simulation of sound fields in enclosures, for instance for application in listening tests, where test subjects assess the sound quality or other sound perception characteristics of the sound field. According to a specific embodiment, the system comprises a binaural synthesis portion which synthesizes sound for instance from a sound-reproduction equipment based on measured impulse responses of an actual room stored in a data base (31) and a binaural recording portion comprising a data base 32 for storing binaural recordings of other sound signals made in the room. Data from these databases are mixed (41) and reproduced by means of a headphone (39) provided with a head tracker (42) for tracking the movements of the listener's head. The invention furthermore comprises the use of cross-fading functions (36, 37) to enable the dynamic listening conditions, where the movements of the listener's head are taken into account during the simulation process.
