SAE Update - December 2021 - 14

FOCUS: NVH
Overcoming fear of
the unknown in NVH
In the late 1980s and early
1990s, many news writers from
the nation's top newspapers
and automotive magazines
came to Detroit to talk with the
OEMs for an understanding of
how the domestic OEMs are
preparing for global
competition.
Quality was obviously the
biggest issue, but with that
came other issues-one of them
being NVH. Some people think
Sound Quality (SQ) was
invented at that time. Although,
SQ has been around for a long
time, automotive globalization
really changed everything. We
had to look at everything
differently.
At the SAE World Congress
(now called WCX) in the
headliner sessions for three
years in a row in the 1990s, an
NVH engineer from a U.S. OEM
and a German headliner
manufacturer disagreed on the
Concern about passenger comfort pre-dated the " horseless carriage. "
acoustics of a headliner in a vehicle.
The U.S. OEM NVH engineer qualified why the
headliner needs to be an acoustics-performing
product and the German headliner manufacturer
justified why the headliner does not need to be an
acoustical part to provide the right acoustic in the
vehicle. You can see, although each vehicle has four
wheels, an engine, and an audio system, the design
philosophies were very different.
Although all OEMs have their own individuality and
uniqueness, when everything is put together, it was
very obvious that there were three different cultures
