  • Publication number: 20200236463
    Abstract: This disclosure relates to a headphone device, a terminal device, an information transmitting method, a program, and a headphone system capable of reducing a process burden of parameter control in a noise canceling process of the headphone device. In the terminal device capable of communicating with the headphone device, a parameter appropriate for the noise canceling process is determined based on analysis of noise from outside and position information and indication information to indicate a processing parameter related to the noise canceling process in the headphone device is generated. This is transmitted to the headphone device side. In the headphone device, a processing parameter of the noise canceling process is set according to the indication information. According to this, a process to determine an optimal parameter of the noise canceling process on the headphone device side is not required.

  • Patent number: 8976978
    Abstract: A sound signal processing apparatus includes a sound source direction determination unit and a filter processing unit. The sound source direction determination unit determines sound source directions with respect to sound signals of a plurality of channels for respective first to n-th bands. The filter processing unit includes first to n-th filters which are connected in series and configured to boost or attenuate the sound signals with respect to the first to n-th bands. The respective first to n-th filters perform boosting or attenuation based on the sound source directions of the first to n-th bands which are determined by the sound source direction determination unit.
