The biggest hit in the A4 to allroad conversion comes from the drag coefficient, which results in
increased wind noise and poorer highway mileage.
Especially given the clunky roof rail removal and the significantly
increased wind noise on the highway even with the top closed.
The only problem I have had is the molding around the driver & passenger windows got crimped, resulting in
increased wind noise.
Not exact matches
Roof open, the buffeting is conspicuous by its absence and is no worse than in others cars with a similar open - roof arrangement (think McLaren 570S Spider), and when the roof is closed only an
increase in
wind noise around the top of the A-pillar can be detected, meaning the i8 remains a great GT - sports car.
Increased dash insulation, added windshield side molding and the increased use of structural adhesive ensure a quiet ride with reduced road and wi
Increased dash insulation, added windshield side molding and the

increased use of structural adhesive ensure a quiet ride with reduced road and
wind noise.
Wind and engine
noise do
increase notably at highway speed, but by no means to the point of aggravation.
Increased Window Thickness Significantly thicker side window glass adds to the 2017 Ridgeline's gains in attenuating
wind, road and mechanical
noise before it reaches the cabin.
At higher speeds the lack of additional gears shows, as the engine
winds up higher and
noise increases.
The shape of the A-pillars and door mirrors were also designed keeping aerodynamic efficiency in mind, while
increased rigidity around the door sashes, delivers improved sealing of the doors to reduce
wind noise.
Turbulent air
increases drag, which adds
wind noise and reduces efficiency.
Increased dash insulation, added windshield side molding, acoustic laminated front door windows and the increased use of structural adhesive ensure a quiet ride with reduced road and wi

increased use of structural adhesive ensure a quiet ride with reduced road and
wind noise.
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
noise increased with the top down, of course, but a
wind screen that folds up behind the front row effectively limited turbulence.
That didn't happen here, although one proposed farm was abandoned because the vibration from the
wind turbines would have
increased the «seismic
noise» at the Laser Interferometry Gravitational Observatory», half of which is located on the Hanford Site, looking for gravitational waves.
Research into aero - acoustic properties will result in both the improved efficiency of
wind turbines and
increased siting opportunities, as the associated
noise is decreased.
Whales and Dolphins can be affected by off shore
wind farms by: • seismic exploration; • intense
noise due to ramming / piling, drilling and dredging operations; •
increased vessel activities during exploration and construction and later maintenance operations, •
increased turbidity due to construction and cable laying; and, later, • decommissioning of
wind farms.
New regulations will include
increasing the setback distance for the turbines, creating tighter
noise restrictions, eliminating turbine flicker for the homes of nonparticipating residents, and a ban on
wind development within three miles of the Lake Huron shoreline.
However, as the
wind speed
increases,
noise from
wind passing through vegetation also
increases which can mask the
noise from
wind turbines.
«With
increased sea ice melt, however, come more waves and
wind, which creates more
noise and makes it harder to track undersea vessels.»
The study did find a correlation, but not a causal relationship, between
increasing levels of
wind turbine
noise and annoyance.
... According to a review by Lovich and Ennen (2013), the construction and operation of
wind farms have both potential and known impacts on terrestrial vertebrates, such as: (i)
increase in direct mortality due to traffic collisions; (ii) destruction and modification of the habitat, including road development, habitat fragmentation and barriers to gene flow; (iii)
noise effects, visual impacts, vibration and shadow flicker effects from turbines; (iv) electromagnetic field generation; (v) macro and microclimate change; (vi) predator attraction; and (vii)
increase in fire risks.
Complaints have also
increased about enormous new
wind turbines» low - frequency
noise.
As for correlation — you're confusing year to year
noise in the surface temperature as heat moves around in the climate system with the documented
increase in net heat, most of which
winds up in the oceans.
Germany made big
noises and lots of
wind turbines, but
increased coal burning to make up for the closing of nuclear power plants, as did Japan.
Most annoyance surveys suggest that
wind farm hosts are less likely to be bothered by turbine
noise than non-participating neighbors, and many
wind projects make an effort to spread the financial benefits to include some non-host neighbors, because of suggestions that broader project participation will
increase community acceptance.
A pair of high - def microphones work to block out
wind and other
noise to
increase call quality and boost voice recognition capabilities.
