When reviewing customer reviews of the first Goodwood Ghost, it was clear that its cocooning and near-silent acoustic properties were of the utmost importance. These men and women operate in complex business worlds and enjoy the sense of calm and well-being that their Rolls-Royce creates. Therefore, when creating the new Ghost, the brand’s team of acoustics specialists obsessively focused on this extremely complex engineering task.
To achieve a feeling of absolute serenity, the acoustic team began by adapting the brand’s proprietary aluminum spatial structure architecture, which itself offers advantages due to the higher acoustic impedance of metal compared to steel and its construction from complex shapes rather than flat, resonant surfaces. A double-walled bulkhead section was chosen to isolate the cabin from the already nearly silent 6.75-liter V12 engine and cavities in the roof, trunk and floor were created to fill with over 100kg of material. sound-absorbing. In addition, double-glazed windows with a transparent composite central sheet were used as well as tires lined with lightweight acoustic insulation foam.
Once the soundstage was created, each component was obsessively questioned for its acoustic properties. Those that produced unacceptable noise levels were rejected and completely redesigned at the Home of Rolls-Royce in Goodwood, West Sussex, to better serve the customer’s desire for peace of mind. Even the inside of the air conditioning ducts have been smoothed out to better insulate customers from intrusive noise.
However, during the first tests, the acoustics team found that the elimination of all noise was disorienting. Their solution was to create a “whisper” – a soft undertone that customers felt as a single, subtle note. To achieve this, each component had to be tuned to a specific resonant frequency. This task included creating acoustically tuned damping units for the seat frames, as well as a series of ports between the cabin and the large 500-liter trunk to ensure that the low frequency generated was consistent with the new ‘ note ”from Ghost.
The brand’s experts have named this comprehensive process the Formula for Serenity. Following its creation, these specialists presented the acoustic advances they had made, showing how these remarkable developments would meet the demands of new Ghost customers. Rolls-Royce has chosen to share material from these internal briefings to demonstrate the technical substance behind this extraordinary new car ahead of its official unveiling in the fall of this year.
Ghost’s new head of acoustical engineering, Tom Davis-Reason, says: “The extraordinary acoustic quality of the new Ghost is the result of significant technical developments and careful attention to detail, but it is really underpinned by the exclusive aluminum architecture of the brand. We simply could not have created such an acoustically refined environment using a steel platform.
The brand has chosen the popular and aesthetic medium of animated illustrations to convey these ideas. Rendered first by acclaimed illustrator Charlie Davis, they have been animated to consistently and beautifully represent these findings in a way befitting the very progressive new Ghost.
In addition to this information presented in animated form, a series of five podcasts have been launched that further reveal the brand’s findings, as well as information about the underlying material and technical substance of the new Ghost in extended 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.
