Modern approaches to electric
vehicle noise and vibration
lighter than other insulators, flameproof,
and temperature resistant up to 180°C.
A sound strategy
The solution is not always to remove noise,
according to Gary Newton, vehicle
dynamics and NVH simulator solutions
sales at VI-grade in Canton, Mich. " For
years, " he said, " we've been trying to bleed
noise out of the vehicle, and now we are
trying to put the 'right' noise back into the
vehicle. On top of that, companies are
looking at how to create the best sound
experience for their brand. People want to
feel a certain way in the vehicle, so how can
we create that 'feel.' " These are the arts of
sound enhancement, sound design, and
active noise control.
Vehicle designers and NVH experts have
been studying very closely the types of
experiences consumers desire with their
vehicles, whether it be performance-related
or comfort. " People want a positive user
experience, and the sound of a vehicle that
is not only pleasing to them, but also that
fits the vehicle, " Newton said. " Consumers
also want a smooth and comfortable ride. "
Sound design and strategies start early in
the vehicle development process and can
entail months of design, testing, and
validation. The process can often be very
expensive and greatly impact an
automaker's time to market. As a result, the
industry has moved more toward using
simulation as a tool for speeding design
iterations, testing, and validation. Simulator

technology has advanced significantly over
the past 20 years and has even enabled
developers to model the acoustic
experience.
VI-grade's NVH driving simulators enable
vehicle design and development engineers
to experience and understand the NVH
characteristics of a vehicle by reproducing
sound and vibration from electric motor,
road, and wind noise contributions. This
leads to fast and confident NVH decisions.
" Today, on a simulator, you can
experience both your electric vehicle's NVH
and vehicle dynamics performance targets
without a prototype. There is real power
being able to subjectively link those
together to accelerate critical decision
making without the harsh consequences of
doing them both independently, " Newton
added.
Take part in further discussions on sound
design and noise mitigation for electric
vehicles at the upcoming SAE Noise and
Vibration Conference & Exhibition, a
hybrid event taking place digitally and inperson
in Grand Rapids, Michigan,
September 7-10, 2021. Visit www.sae.org/
