    摘要： The multi-micro hollow cathode light source has a cathode plate, an insulation plate, an anode plate, and metal pieces. The insulation plate is sandwiched by the cathode plate and the anode plate. The cathode plate is made of copper. The centers of the cathode plate, insulation plate, and anode plate, are provided with holes, respectively. The holes form a penetrating though-hole. Linear slots are disposed in the cathode plate continuously extending from the hole in a cross shape. Each slot penetrates the cathode plate. Four metal pieces made of materials different from one another are inserted and buried in the four slots.

    摘要： A noise reduction device including a noise detection microphone including a high-frequency noise detection microphone and a low-frequency noise detection microphone for respectively detecting a high-frequency noise and a low-frequency noise generated from a noise source; a noise control unit for generating a control sound signal for cancelling a noise detected by the noise detection microphone in a control center of control space; and a loudspeaker for outputting a control sound based on the control sound signal from the noise controlling unit. The high-frequency noise microphone is disposed in a vicinity of a head portion of a user in a state in which directivity in an opposite direction with respect to the control center is added, and the low-frequency noise detection microphone is disposed outside of a sound-insulating wall.

    摘要： A sound field measuring device uses a measurement signal which has at least one change point and whose frequency spectrum has a shape corresponding to a shape of a frequency spectrum of a background noise. This enables a sound field measurement, which is for measuring an impulse response or transfer function of a sound field space which is a linear time-invariant system to be measured, to be performed with a high S/N ratio over a wide frequency band.

    摘要： In a noise reduction apparatus for controlling noise up to a predetermined upper limited frequency, a distance from a noise source to control point X is made larger than a distance obtained by subtracting a one-half wavelength from a distance, obtained by adding up a distance from the noise source to a noise detecting microphone, a distance corresponding to time as a sum of respective delay time of the noise detecting microphone, a noise controller, and a control speaker, and a distance from the control speaker to control point X, where one wavelength is a period corresponding to the upper limited frequency.
