cultures.
There is often a
reluctance to accept the

industry and the NVH
industry are not too far

vehicles to the
automobile was the same.
Average people could not
afford it, they feared the
unknown and the speed.
Going from an ICE (internal
combustion engine) to an
EV (electric vehicle) and
eventually to an AV
(autonomous vehicle) has
similar concerns as well.
Although most of us are
delighted and excited
about new technology,
many of us are concerned
of the safety of both EVs
and AVs. In particular, the
AV's interior is likely to be
re-landscaped more

have ever experienced.
With that comes the
concerns of the safety of

these concerns are addressed properly.
The reluctance of accepting unknowns affects the NVH
