1. a kind of hearing-aid device, including:

  • Active noise reduction system, the sound source for reducing from positioned at the space for surrounding user reaches the ambient sound of the ear of userSound level,Two transducers on the hearing-aid device, are felt for sensing sound present in the space and exporting to representThe signal of the sound of survey;

    At least one loudspeaker, for reproducing sound, so as to be presented to the user;

    AndSignal processing system, for being located at the space relative to the sound source enhancing in the unintended areas in the spaceSound source in expected areas, wherein the output of the signal processing system be provided back to by least one described loudspeaker it is describedUser,The signal exported by described two transducers is transformed into frequency domain by wherein described signal processing system, the pin in block-by-block basisThe relation set up to each storehouse between the frequency domain representation of the transducer signal, performs the relation and the predetermined ratio for receiving criterionCompared with the gain in each storehouse based on the frequency domain representation for comparing and determining to be applied to the transducer output signal is to form multiple increasingsBenefit change frequency-region signal, and the frequency-region signal that the multiple gain is changed convert back time-domain signal so as to by it is described at leastOne loudspeaker reproduction.
