    摘要： The invention relates to a system for measuring vibration on a machine, with a carrier (14) for placing onto a measuring point (12) of the machine, a sensor (16) arranged on the carrier for detecting vibrations, an arrangement (16, 22, 28, 30) for detecting the electromechanical impedance of the sensor and also a monitoring device (22, 24, 26) for monitoring the current coupling of the carrier at the measuring point by means of evaluating the detected electromechanical impedance. The current coupling is in this case determined from the difference between the currently detected electromechanical impedance and the electromechanical impedance detected for a prescribed optimum coupling of the carrier to the measuring point.

    摘要： A sound focusing mechanism for generating a focused source of sound provides for identifying a transmission loss of an object, areas of acoustic or thermal leakage within or acoustic flanking paths associated with the object. The sound focusing mechanism includes a housing having at least one wall formed from a material having high sound transmission loss properties. A sound generating device for generating a sound is located with a central cavity within the housing. An actuator assembly is operatively connected to the sound generating device for selectively operating the sound generating. The sound focusing mechanism is used in a method of determining the sound transmission loss and flanking paths of an object, as well as thermal loss.

    摘要： A sound focusing mechanism for generating a focused source of sound, which can be used to identify the transmission loss of an object or identify areas of acoustic or thermal leakage is disclosed. The sound focusing mechanism includes a housing having at least one wall formed from a material having high sound insulating properties. A sound generating device for generating a sound is located with a central cavity within the housing. An actuator assembly is operatively connected to the sound generating device for selectively operating the sound generating device for selectively operating the sound generating device. The wall is configured to limit the transmission of the sound there through such that a focused beam or pulse sound is emitted from the mechanism through the opening.
