    摘要: Provided is a technique for improving frequency characteristics by an acoustics-related method so that a sound is heard with natural frequency characteristics when a sound-isolating earphone is fitted in a human ear. A sound-isolating earphone is provided with two or more electroacoustic transducers, wherein independently generated sound waves are passed through isolated sound leading pipes and are mixed just before an entrance of an external auditory canal, and a sound wave of which is twice the difference between path lengths of the two sound leading pipes is attenuated. This serves to provide an easy-to-hear improved sound quality by suppressing the sound wave at around 6 kHz that is transmitted with characteristically high intensity in a sound-isolating earphone.

    摘要: An electroacoustic transducer apparatus of a type that it is inserted into a cavum concha upon use. The electroacoustic transducer apparatus of the invention is applied to a headphone of a so-called in-the-eart type or so-called inner-ear type. This headphone is provided with an air passage portion formed through an elastic ring member attached to the outer peripheral portion of the housing so as to communicate the inside and outside portions of a concave portion of the cavum concha upon use. Accordingly, a certain amount of sound escapes to the outside, thereby obtaining the acoustic characteristics of substantially the same level from a low band to a high band regardless of the size of the user's ears.

    摘要: A leak detecting method and apparatus for a gas pipe line in which the inflow rate Qin or the outflow rate Qout is measured from instant to instant at each of all the inlet and outlet ports of the gas pipe line and the presence or absence of a gas leak is determined in accordance with the measured values. The measured inflow rates Qin and outflow rates Qout are respectively integrated over a given period of time and the occurrence of a gas leak is determined when the sum .SIGMA..intg.Qdt of the integrated values deviates from a predetermined value. On that occasion, in accordance with the data obtained by these calculations the relation between the integration time and the standard deviation of .intg.Qindt-.intg.Qoutdt/.intg.Qindt is calculated so that in accordance with the relation an integration time T corresponding to a rate of leakage to be detected is determined and the integration over time is performed from each of a plurality of time instants shifted from each other by an integral fraction of the integration time T whereby the above-mentioned determination is made each time the integration time T is reached.
