Helicopter rotor systems are central to both civil and military applications, yet they continue to face challenges associated with vibration and noise. These issues not only affect passenger comfort ...

Disruption of a payload can be caused by three of the primary sources of vibration (or noise): ground vibration, acoustic noise, and direct force disturbances. Ground, or seismic vibration, is present ...

Three tools are typically used to measure vibrational noise (noise) - a storage Oscilloscope (scope); a vibration sensor (sensor), which is generally a 'seismic grade' accelerometer 1; and a ...

WAJDA: Vibration is the oscillation of a body around a reference point. Vibration exists when a system responds to some internal or external excitation. Vibration is a dynamic response to a dynamic ...

Vibration is that repeating switch from kinetic to potential energy resulting from pushing, stretching, or suspension. Because it’s so often observed as waves through matter, it’s also the most ...

European researchers have concluded – perhaps unsurprisingly – that noise and vibration are the biggest sources of passenger discomfort in turboprop aircraft. And they stress that such issues must be ...

Though electric vehicles (EVs) are intrinsically less noisy than internal combustion engine (ICE) cars, automakers are still focused on further lowering in-cabin noise due to wheel or vibration. A new ...

ClassNK released its new Noise and Vibration Guideline for measuring and evaluating the noise and vibration on ships. The new Guideline address the growing demand for new standards for noise and ...

For decades, carmakers treated cabin noise as a single number problem, something to be tamed with thicker glass and extra ...

Engineers are not just adding more insulation, they are reinventing how interior noise is captured, modeled, and judged so ...

The Toronto Transit Commission has turned to engineering experts for help in determining what’s behind excessive subway noise and vibration amid recent complaints from several Danforth neighbourhood ...
