    • The invention relates to a listening device for processing an input sound to an output sound. The invention further relates to a method of estimating a feedback transfer function in a listening device. The object of the present invention is to provide an alternative scheme for minimizing feedback in listening devices. The problem is solved in that the listening device comprises an input transducer for converting an input sound to an electric input signal and defining an input side, an output transducer for converting a processed electric output signal to an output sound and defining an output side, a forward path being defined between the input transducer and the output transducer, and comprising a signal processing unit adapted for processing an SPU-input signal originating from the electric input signal and to provide a processed SPU-output signal, and an electric feedback loop from the output side to the input side comprising a feedback path estimation unit for estimating an acoustic feedback transfer function from the output transducer to the input transducer, and a enhancement unit for estimating noise-like signal components in the electric signal of the forward path and providing a noise signal estimate output, wherein the feedback path estimation unit is adapted to use the noise signal estimate output in the estimation of the acoustic feedback transfer function. This has the advantage of providing an adaptive feedback cancellation system which is robust in situations with a high degree of correlation between the output signal and the input signal of a listening device. The invention may e.g. be used in hearing aids, head sets, mobile phones, wearable/portable communication devices, etc.

    • A storage cell (1) having a pulse generator (5) and a storage element (6) is proposed. The storage element input (7) is connected to receive a data input signal (DIN). The storage element output (9) is connected to provide a data output signal (DOUT). The storage element (6) is operable in one of a data retention state and a data transfer state in response to a storage control signal (SC) received from the pulse generator (5). The pulse generator (5) is connected to receive a clock signal (CK) with rising and falling clock signal edges (13, 14) and is adapted to provide control pulses (15, 16) in the storage control signal (SC). Each control pulse (15, 16) has a leading edge (17) and a trailing edge (18). The control pulses (15, 16) have a polarity suited to invoke the data transfer state on their leading edges (17). The novel feature is that the pulse generator (5) is adapted to initiate a rising-edge control pulse (15) when receiving a rising clock signal edge (13) and to initiate a falling-edge control pulse (16) when receiving a falling clock signal edge (14). In this way, a dual-edge- triggered flip-flop may be made using only combinatorial logic circuitry and one level- or single-edge-triggered storage element (6). The storage cell (1) has low power consumption, facilitates scan testing and can be used by existing design tools and test equipment.

    • The invention relates to a hearing aid system with an electrical feedback cancellation path, for compensating acoustic feedback between an output transducer and an input transducer by subtracting an estimate of the acoustical feedback from a signal on the input side of the amplifier part, the electrical feedback cancellation path comprising an adaptive filter for providing a variable filtering function. The invention further relates to a method of compensating acoustic feedback in a hearing aid system and to its use. The object of the present invention is to provide an alternative scheme for estimating the acoustical/mechanical feedback in a hearing aid. The problem is solved in that the hearing aid system comprises a second electrical input signal consisting essentially of the direct part of said first electrical input signal (i.e. without acoustic feedback), and wherein the second electrical input signal is used to influence, preferably enhance, the filtering function of the adaptive filter of the feedback cancellation path. Preferably, the system comprises a second input transducer for generating the second electrical input signal, the second input transducer being spatially located at a position where the amplitude of the acoustical signal from the output transducer at a given frequency is smaller than at the location of the first input transducer, and wherein the electrical signal of the second input transducer is used to adapt the filtering function of the adaptive filter. Preferably, the signal path comprises a generator of an electrical probe signal for use in characterizing the feedback path. The invention may e.g. be used in binaural hearing aid systems or in connection with other electronic devices comprising a second electrical input signal, e.g. generated by a microphone separately located from a first microphone of the hearing aid.
