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 an earhole-wearable sound collection device, a signal processing device, and a method for realizing sound collection at a high S/N ratio. 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 (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. Therefore, the S/N ratio of an emitted speech voice collection signal is improved by an equalizing process for reducing muffled sound that is generated when sound is collected through the ear canal on the sound collection signal.

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 noise influence being reduced not by a noise reduction process.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 (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. Therefore, the S/N ratio of an emitted speech voice collection signal can be improved by extracting the low-frequency component of the sound collection signal with the use of a LPF, for example. Alternatively, 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. As a result, higher sound quality can be achieved.
