Such breakthroughs reflect a variety of factors, notably including more advanced aerodynamic designs that not only reduce wind resistance but
also lower wind noise.
Not exact matches
Mercedes says the car will have the
lowest wind -
noise levels in the midsize luxury class, adding it
also has class - leading aerodynamics with a 0.24 coefficient of drag.
To
lower wind noise in the cabin, aerodynamics have
also been improved to 0.33 Cd, a 0.02
lower coefficient of drag (Cd) than the former model
It
also has GM's state - of - the - art
noise insulation technologies,
lowering engine, road and
wind noise by means of isolation, absorption and reduction.
The developers
also placed great importance on achieving a
low level of
wind noise, minimal aerodynamic drag for
low fuel consumption, and thermal robustness for all systems.
As the speed increases, ABC
also lowers the vehicle below the static ride height (maxing out at about 0.5 inch at about 80 mph) to reduce
wind resistance for better fuel economy and reduced
noise and
lower the center of gravity for better high - speed stability.
The consequences of exposure to impulsive infrasound and
low frequency
noise generated by
wind turbines were
also clearly well known to the global
wind industry, because of the dramatic change in design which resulted, and because the results were presented at the AWEA sponsored conference.
Complaints have
also increased about enormous new
wind turbines»
low - frequency
noise.
There is
also less splashing,
lower levels of road
noise and much less
wind buffeting of other cars thanks to the improved aerodynamics.
