Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
Pirelli has been sponsoring sport competitions since 1907 and is the exclusive tyre partner and supplier for the Grand-Am Rolex Sports Car Series for 2008–2010, FIA Formula One World Championship for 2011–present and for the FIM World Superbike Championship. [7] Pirelli's headquarters are located in Milan's Bicocca district. Pirelli is now ...
While the elderly may have cardiac problems due to noise, according to the World Health Organization, children are especially vulnerable to noise, and the effects that noise has on children may be permanent. [45] Noise poses a serious threat to a child's physical and psychological health, and may negatively interfere with a child's learning and ...
The Hum is a name often given to widespread reports of a persistent and invasive low-frequency humming, rumbling, or droning noise audible to many but not all people. Hums have been reported all over the world, including the United States, the United Kingdom, Australia and Canada.

"ELT": Pirelli Elect tyres, specific for ...
The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
Police in Laos have detained the manager and seven staff members of a backpacker hostel in Vang Vieng following the deaths of six tourists from suspected methanol poisoning, state media reported ...
Apart from man-made noise, it is the strongest component over the range of about 20 to 120 MHz. Little cosmic noise below 20MHz penetrates the ionosphere, while its eventual disappearance at frequencies in excess of 1.5 GHz is probably governed by the mechanisms generating it and its absorption by hydrogen in interstellar space.
