    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.

    Abstract translation: 本技术涉及一种用于以高S / N比实现声音采集的耳机佩戴式声音采集装置，信号处理装置和声音采集方法，其噪声影响不是通过降噪处理而减少的。 在耳机佩戴式收音装置中，收集发出的语音的麦克风设置在基本上与外部密封并连接到佩戴者（扬声器）的耳道的空间中。 麦克风位于从外部密封的空间中，收集通过穿戴者的耳道传播的发出的语音。 在通过耳道获得的声音收集信号中，所发出的语音分量在噪声分量上占优势，特别是在低频下。 因此，例如，通过使用LPF提取声音采集信号的低频分量，可以提高发出的语音语音采集信号的S / N比。 或者，对声音采集信号执行用于减少通过耳道收集声音时产生的消声的均衡处理。 因此，可以实现更高的音质。

    Abstract: According to the present disclosure, a sound output device includes: a sound acquisition part configured to acquire sound to be output to the other end of a sound guide part, one end of which is arranged near an entrance of an ear canal of a listener, the sound guide part having a hollow structure; and a head-related transfer function adjustment part configured to adjust a head-related transfer function of sound captured by the sound guide part. Since the head-related transfer function adjustment part adjusts the head-related transfer function of sound captured by the sound guide part, it is possible to listen to both ambient sound and sound provided from a sound output device such that the listener does not feel strangeness even in the state in which the listener is wearing the sound output device.

    Abstract: The present disclosure relates to an information processing apparatus and method capable of performing compensation to achieve a standard sound regardless of a recording environment. The microphone picks up sound from a sound source and inputs the sound to a recording apparatus as an analog audio signal. The recording apparatus is an apparatus that performs binaural recording and generates an audio file of a sound obtained by binaural recording. The recording apparatus adds metadata related to a recording environment of binaural content to the audio file generated by binaural recording and transmits the file with the metadata to a reproducing apparatus. The present disclosure is applicable to a recording/reproducing system that performs binaural recording and reproduction of the sound, for example.

    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.

    Abstract: [Object] To provide a sound processing device capable of effectively reducing ambient noise at low cost.[Solution] Provided is a sound processing device including: a first sound collector configured to collect a first noise signal from a noise source of noise leaking into a casing mounted to a user's ear; a first signal processing unit configured to form a first noise reduction signal used to reduce noise at a cancellation point on the basis of the first noise signal; a second signal processing unit configured to form a second noise reduction signal used to reduce noise at a cancellation point with respect to a first pseudo noise signal; an adder configured to add the first noise reduction signal and the second noise reduction signal; and a sound emitter configured to emit an output of the adder into the casing as sound. The first pseudo noise signal is a signal obtained by subtracting an output of the adder applied with a simulation transfer characteristic from an output of the first sound collector, the simulation transfer characteristic being obtained by simulating a transfer characteristic from the sound emitter to the first sound collector.
