Abstract: The present technique relates to an earhole-wearable sound collection device, a signal processing device, and a sound collection method for realizing sound collection at a high S/N ratio with reduced noise influence, regardless of noise reduction methods such as the SS method.In the earhole-wearable sound collection 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, so that emitted speech voice propagating through the ear canal of the wearer is collected. A noise cancelling unit that reduces noise propagating in the internal space having the microphone located therein is further provided to improve the S/N ratio of emitted speech voice collection signals. Further, an equalizing process for reducing the muffled sound generated when the emitted speech voice propagating through the ear canal is collected is performed on the sound collection signal from the microphone. In this manner, higher sound quality is achieved.

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.

Abstract: A signal processing apparatus includes a signal processor configured to: generate a first noise reduction signal using an adaptive filter based on a signal output from a first input apparatus, and cause the generated first noise reduction signal to be output by a first output apparatus; and generate a second noise reduction signal using a feedback filter based on a signal output from a second input apparatus, and cause the generated second noise reduction signal to be output by a second output apparatus. The feedback filter has a fixed feedback coefficient. The first input apparatus is located at a first noise-cancellation target location in an environment, and the second input apparatus is located at a second noise-cancellation target location in the environment, which may be different from the first noise-cancellation target location.
