听力原文: Objects that are vibrating make sounds. Rhythmic sound vibrations produce sound waves which travel in every direction. The frequency of a sound is the number of waves that pass a given point each second. [29] The more rapid, an object vibrates, the greater the frequency of sound...

some metal objects or equipment including above-ground or buried metal piping may respond to 60-cycle electrical field-induced vibration where piping passes below electrical power lines. Field example: in the 1970's we found that stopping our dirt-bike motorcycle below the Fishkill N.Y. power ...
Surface profile measurement of low-frequency vibrating objects using temporal analysis of fringe pattern A simple and accurate algorithm (phase scanning method) is proposed for 3D surface contouring and dynamic response determination of a vibrating object. A s......
At this point it is clear how the predefined objects have been achieved. With the system and the method according to the invention, stimulation of the cutaneous mechanoreceptors with the consequent desired effects may be effectively applied in a highly precise and programmed manner. ...
This is why shorter strings typically produce a louder and clearer sound. 5. Are energy losses in a vibrating string always undesirable? Not necessarily. In some cases, a certain level of energy loss can be desirable. For example, it can help create a softer and more mellow tone in ...
Such objects of the present invention can be accomplished by providing a device (20,100) for vibrating a string instrument (1) provided with a bridge (13), comprising: a base member (22,102) provided with a load point member (24,156) that engages the bridge (13); and a vibration gene...
