ActiveUS20100303267A1Good front-rear estimationEnhance front-rear localizationTransducer casings/cabinets/supportsDeaf-aid setsData processing systemSound sources
The invention relates to a listening device comprising an ear-part adapted for being worn in or at an ear of a user, a front and rear direction being defined relative to a person wearing the ear-part in an operational position. The invention further relates to a method of operating a hearing instrument, to its use, to a listening system, to a computer readable medium and to a data processing system. The object of the present invention is to provide localization cues for indicating a direction of origin of a sound source. The problem is solved in that the listening system comprises (a) a microphone system comprising at least two microphones each converting an input sound to an electrical microphone signal, (b) a DIR-unit comprising a directionality system for providing a weighted sum of the at least two electrical microphone signals thereby providing at least two directional microphone signals having maximum sensitivity in spatially different directions and a combined microphone signal, and (c) a frequency shaping-unit for modifying the combined microphone signal to indicate directional cues of input sounds originating from at least one of said spatially different directions and providing an improved directional output signal. This has the advantage of providing an alternative or an addition to natural localization cues. The invention may e.g. be used in listening devices, e.g. hearing instruments, head phones, headsets or active ear plugs.

Microphone apparatus and headset

The present invention relates to a microphone apparatus (30) with a main beamformer (31) that provides a main output audio signal (SM) as a beamformed signal by applying a main weight vector (BM) to a main input vector (MM). A main beamformer controller (32) repeatedly determines a main steering vector (dM) and adaptively determines the main weight vector (BM) in dependence on the main steering vector (dM) and the main input vector (MM) to increase the relative amount of voice sound (V) from the user (6) in the main output audio signal (SM).
The microphone apparatus (30) further comprises an auxiliary beamformer (33) that provides an auxiliary beamformer signal (SF) as a beamformed signal by applying an auxiliary weight vector (BF) to an auxiliary input vector (MA) that is a subset of the main input vector (MM), and an auxiliary beamformer controller (34) that adaptively determines the auxiliary weight vector (BF) to increase the relative amount of voice sound (V) from the user (6) in the auxiliary beamformer signal (SF). The main beamformer controller (32) determines the main steering vector (dM) in dependence on the auxiliary weight vector (BF).
This may enable the main beamformer controller (32) to utilize information derived independently of the steering vector (dM) and may thus improve stability and/or accuracy of the estimation of the steering vector (dM), and may further reduce the computation load for the main beamformer controller (32).
