  • Patent number: 11070910
    Abstract: The present technique relates to a processing device and a processing method for realizing sound collection at a high S/N ratio, with noise influence being reduced not by a noise reduction process. In the processing device, a microphone that collects emitted speech voice is provided in a space that is substantially sealed off from outside and connects to an ear canal of the wearer (the speaker). With the microphone being located in the space sealed off from outside, emitted speech voice that propagates through the ear canal of the wearer is collected. In a sound collection signal obtained through the ear canal, the emitted speech voice component is dominant over the noise component particularly at low frequencies Further, an equalizing process for reducing muffled sound that is generated when sound is collected through the ear canal is performed on the sound collection signal.
