He brought Bell to his house and showed him what Helmholtz had done--how he had kept tuning-forks in vibration
by the power of electro-magnets, and blended the tones of several tuning-forks together to produce the complex quality of the human voice.
But scientists working in Samburu have found that elephants also communicate a lot by thumping the ground to create vibrations
, which we humans cannot hear.
The counterbalance impact of tungsten balls in the PID dampens fundamental frequency fa mode vibrations
in the PCB assembly.
induced by road transport is common source of environmental problem for residents living near roads where large flow of vehicles is.

The application of vibrations
at the micro-drilling, especially for deep holes, presents a possible progress in solving those issues to increase the reliability of micro drilling processes.
Not only does it support the engine, it also absorbs the vibrations
generated by the engine, reducing vibrations
of the vehicle frame and vibrations
felt inside the vehicle.
User comments include one saying it proved "very useful and handy for supporting mechanical engineering tests" while another said they used it for testing vibrations

The process of vibration
monitoring depends on an assortment of precision techniques and technologies for detecting vibrations
in the machine.
The first wide studies of shock and vibrations
can be traced to the 1930s when the effects of earthquakes on buildings were being studied in order to improve the behavior of buildings.
