    Abstract: There is provided a system for estimating a total acoustic attenuation of a hearing protection device including an interface at a distal end and a sound canal extending from the interface to a sound opening at a medial end of the hearing protection device. The system comprises: a measurement unit including a loudspeaker and a microphone and being attachable to the interface in such a manner that, when the hearing protection device is worn in an ear canal of a user, the loudspeaker and the microphone are in acoustic communication, via the sound canal of the hearing protection device; a control unit configured to provide the loudspeaker with test audio signals to generate test sounds in the occluded ear canal volume and to receive test response audio signals captured by the microphone from the test sounds; and an evaluation unit configured to estimate a leakage acoustic impedance.

    Abstract: A hearing system having a hearing device, including a receiver antenna assembly with a receiver core having a relatively high magnetic permeability and a receiver coil wound around the receiver core, operably connected to a rechargeable power source, and a hearing device charger, including a transmitter antenna assembly, with a transmitter core having a relatively high magnetic permeability and a transmitter coil wound around the transmitter core, operably connected to a power supply. The respective configurations of the hearing device and the hearing device charger may be such that when the hearing device is in a charging position on the hearing device charger, the receiver core and the transmitter core together provides a closed loop path for magnetic flux.
