摘要： Provided is a wind detection apparatus which can accurately detect wind. The wind detection apparatus 1 comprises a plurality of microphones 11, 12, a spectrum analyzer unit 22 for acquiring a frequency characteristic representing a sound pressure at each frequency band area from a plurality of sound signals detected by the two microphones 11, 12, a sound pressure/dispersion comparison unit 23 for comparing the acquired frequency characteristics (sound pressure/dispersion) of the two microphones 11, 12, and a wind determination unit 24. The wind determination unit 24 determines in accordance with the comparison results of the sound pressure/dispersion comparison unit 23 that the sounds detected by the two microphones 11, 12 are wind sounds when the difference between the sound pressures of the two microphones 11, 12 is detected throughout the predetermined frequency band areas.

摘要： A sound source detecting system that detects a predetermined sound source on the basis of sounds collected by sound collectors includes: a noise extracting unit that extracts a noise from signals of the collected sounds; and a noise suppressing unit that suppresses a signal component of the noise extracted by the noise extracting unit from the signals of the collected sounds. The sound source detecting unit detects a location of the predetermined sound source, such as an approaching vehicle, using information about the sounds having the signals of which the noise is suppressed.

摘要： A signal separation system includes: an external microphone; an internal sensor that detects only an internal noise from an internal noise source present inside the system; a discrete Fourier transform unit (310) that performs a discrete Fourier transform on signals from the external microphone and the internal sensor; an independent component analysis unit (320) that performs independent component analysis on transformed signals that have been subjected to a discrete Fourier transform so that an internal noise separated signal that contains only the internal noise is extracted on the basis of the transformed signal of the signal detected by the internal sensor and external separated signals that are independent of the internal, noise separated signal and that do not contain the internal noise are extracted; and a permutation solving unit (340) that executes permutation solving on the external separated signals to extract a specific voice.
