Soft whirring sound of low-frequency vibrations cannot be easily detected because it is not loud. But once detected, it can be hard to ignore. Often, residents complain of the annoyance caused by ...

Technology advances have steadily been implemented to improve the performance of commercial atomic force microscopes (AFMs) since the release of the first commercial model about 30 years ago. Now, the ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

Vibration analysis is a powerful and non-invasive way to measure, understand, and quantify the internal dynamics of mechanical systems, but the cost of the necessary instrumentation is sometimes a ...
