ROLLS-ROYCE REVEALS ‘FORMULA FOR SERENITY’
Tue Aug 18 01:00:00 CEST 2020 Press Release
When reviewing client feedback from the first Goodwood Ghost, it was clear that its cocooning, near-silent acoustic properties were of the utmost importance. These men and women operate in complicated business worlds and value the sense of calm and wellness that their Rolls-Royce creates. Therefore, in creating new Ghost, the marque’s team of acoustic specialists were obsessively focussed on this highly complicated engineering task.

When reviewing client feedback from the first
Goodwood Ghost, it was clear that its cocooning, near-silent acoustic
properties were of the utmost importance. These men and women operate
in complicated business worlds and value the sense of calm and
wellness that their Rolls-Royce creates. Therefore, in creating new
Ghost, the marque’s team of acoustic specialists were obsessively
focussed on this highly complicated engineering task.
To achieve a sense of absolute serenity, the acoustic team began
by adapting the marque’s proprietary aluminium spaceframe
architecture, which itself offers benefits owing to the metal’s higher
acoustic impedance compared with steel and its construction from
complex forms rather than flat, resonant surfaces. A double-skinned
bulkhead section was selected to insulate the cabin from the already
near-silent 6.75-litre V12 engine and cavities in the roof, boot and
floor were created to fill with more than 100kg of sound-absorbing
materials. Additionally, double-glazed windows with a clear composite
centre sheet were used as well as tyres lined with lightweight
acoustic insulation foam.
Once the sound stage was created, every component was
obsessively interrogated for its acoustic properties. Those that
produced unacceptable levels of noise were discarded and completely
redesigned at the Home of Rolls-Royce in Goodwood, West Sussex, to
better serve the client’s desire for serenity. Even the inside of the
air conditioning ducts were smoothed to better insulate clients from
intrusive noises.
However, upon early testing the acoustic team discovered that
removing all noise was disorientating. Their solution was to create a
‘whisper’ – a soft undertone that clients experienced as a single,
subtle note. To achieve this, each component had to be tuned to a
specific resonant frequency. This task included the creation of
acoustically tuned damping units for the seat frames, as well as a
suite of ports between the cabin and the large 500-litre boot to
ensure the low frequency it generated was consistent with new Ghost’s ‘note’.
The marque’s experts named this exhaustive process the Formula
for Serenity. Following its creation, these specialists presented the
acoustic advances they had made, showcasing how these remarkable
developments would serve the demands of new Ghost clients. Rolls-Royce
has elected to share elements of these internal briefings to
demonstrate the engineering substance that underpins this
extraordinary new motor car ahead of its official unveiling in autumn
this year.
New Ghost Acoustic Engineering Lead, Tom Davis-Reason, says,
“The extraordinary acoustic quality of new Ghost is the result of
significant engineering developments and fastidious attention to
detail, but it really is underpinned by the marque’s proprietary
aluminium architecture. There is simply no way we could have created
such an acoustically refined environment using a steel platform.”
The marque chose the popular and aesthetically appealing medium
of animated illustrations to convey these insights. Rendered first by
renowned illustrator, Charlie Davis, they were animated to cohesively
and beautifully represent these findings in a fashion that befits the
highly progressive new Ghost.
In addition to these insights presented in animation form, a
series of five podcasts have been launched that reveal more of the
marque’s findings, as well as insights into the underlying material
and engineering substance of new Ghost in long form. Hosted by Johanna
Agerman Ross, Curator of Twentieth Century and Contemporary Furniture
and Product Design at the Victoria & Albert Museum in London, the
podcasts are available on Apple,
Google,
Spotify
and Deezer.
