    Abstract: The invention concerns a communication device for placement at the ear of a user. A battery and transmission part is shaped to rest behind and above the ear lobe of a user and a speaker and microphone part is arranged to extend downwards in front of the ear canal. The two parts are interlinked to pivot, at least in the sagittal plane, with respect to each other and the battery and transmission part accommodates a battery as well as signal processing and transmission electronics, and the speaker and microphone part accommodates a speaker element and a microphone boom arm and further, the two parts have mating surfaces such that a pivotal motion between the two, when the device is not at the ear, will bring a surface of the first part and a surface of the second part together. Further the link between the two parts comprises a hollow ball joint connection allowing leads to pass through the ball joint. Also a magnet is inserted in the one part and a sensor for sensing the magnetic field from the magnet is comprised in the other part, such that the movement between the two parts may be registered and used to control the function of the device or for giving audible indication signals to the user.

    Abstract: The invention relates to an adaptive filter unit, in particular for being used as an echo canceller, comprising a first filter input, configured to receive a first electric audio signal, indicative of a first audio signal A(t), a second filter input, configured to receive a second electric audio signal, indicative of a second audio signal B(t), a processor and a filter output. The processor is configured to calculate and provide audio estimation data X(fn, A(t1, . . . , tM(fn))) in the frequency domain; to calculate a transformed second audio signal Y(fn, B(t)), formed by a transformation of the second audio signal B(t) into the frequency domain; and to calculate a filtered audio signal by subtracting delayed audio estimation data from the transformed second audio signal, wherein the delayed audio estimation data is provided by a memory unit of the adaptive filter unit, which is arranged to provide a data exchange with the processor, and wherein the delayed audio estimation data comprises a frequency dependent time delay compared to the transformed second audio signal.

    Abstract: The application relates to a loudspeaker system including an input unit providing an electric input audio signal; an equalization unit for modifying said electric input audio signal in dependence on frequency and to provide an equalized electric audio signal according to a predefined equalization function, a loudspeaker unit for converting said equalized electric audio signal to an acoustic output sound signal, and a user interface for modifying a volume level of said output sound signal in a multitude (N) of steps V0, V1, . . . , VN. The application further relates to a method communication device comprising the loudspeaker system and to its use. The present application provides an improved loudspeaker system in which the equalization unit is configured to apply a specific equalization function EQ0, EQ1, . . . , EQN to the electric input audio signal in each of said multitude of steps V0, V1, . . . , VN of the volume level.

    Abstract: A hearing device comprises a receiver, an input buffer and a sample processor, the receiver being adapted to receive samples of a digital audio signal and feed received samples as a digital input signal to the input buffer, the sample processor being adapted to process the buffered samples to provide samples of a digital output signal such that the digital output signal is a sample-rate converted representation of the digital input signal with a predetermined target sample rate. The hearing device further comprises a latency controller adapted to estimate the quality of reception of the digital audio signal and to control the processing of the buffered samples in dependence on the estimated quality of reception.
