  • Active monitoring headphone and a binaural method for the same
    Patent number: 10706869
    Abstract: According to an example aspect of the present invention, there is provided a method for forming a binaural filter for a stereo headphone in order to preserve the sound quality of the headphone, whereby the sum of the direct and crosstalk paths from loudspeakers to each ear have flat magnitude responses.
    Type: Grant

  • Active monitoring headphone and a method for regularizing the inversion of the same
    Patent number: 10582325
    Abstract: According to an example aspect of the present invention, there is provided a Method for regularizing the inversion of a stereo headphone transfer function for headphone equalization, characterized by using the equation for the equalization: H S ? ? 1 - 1 ? ( ? ) = H * ? ( ? ) ? H ? ( ? ) ? 2 + ? ^ ? ( ? ) ? D ? ( ? ) = H * ? ( ? ) ? H ? ( ? ) ? 2 + [ ? ? ( ? ) + ? 2 ? ( ? ) ] ? D ? ( ? ) . in which equation HSI?1(?) is sigma inversion H*(?) is complex conjugate of a response D(?) is a delay filter introduced to produce a causal inverse HRI?1(?) H*(?) a response ?(?) is headphone reproduction bandwidth, ?(?) an estimation of the regularization needed inside that bandwidth.
