New Rolls-Royce Ghost: acoustic tuning to boost luxury feel

Rolls-Royce has detailed the measures it has taken to reduce noise inside the   next-generation Ghost, including a series of   'acoustic tuning' measures to make the cabin calmer   and more comfortable.

The second-generation luxury saloon, due to be revealed next month, will gain   four-wheel drive and a raft of upgrades - and Rolls-Royce has also taken measures to ensure it enhances its credentials by reducing noise inside.

Citing customer feedback affirming that interior comfort is a key consideration for customers, Rolls-Royce's designers undertook a process to minimise the noise disruption inside the cabin.

The process, which the firm called its Formula for Serenity, involved adding extra insulation to the aluminium chassis, with a double-skinned bulkhead section between the cabin and the 6.75-litre V12 engine to reduce noise from the unit. Sound-absorbing materials were also added in the roof, boot and floor.

Rolls-Royce then reviewed individual parts to minimise the noise they produced, for example smoothing the inside of the air conditioning ducts.   To ensure the cabin wasn't disconcertingly quiet, the firm then undertook a process of "acoustic tuning",   tuning each component to a specific frequency to create a single small noise, which it calls a 'whisper'. To do that, engineers developed new damping units for the seat frames   and new ports between the cabin and boot.  

The measures Rolls-Royce has taken to reduce noise in the new Ghost's cabin were outlined in the latest of a series of animated films, in which the firm has detailed several key features of the new car. These include a video highlighting the new all-wheel-steering system, previously seen on the latest Phantom, and the switch from rear- to four-wheel-drive.

Rolls-Royce has also detailed a new suspension technology making its debut on the Ghost. Called the Planar system, it features what the firm   describes as a "world-first technology" in the form   of an upper wishbone damper unit mounted above the front suspension assembly for "an even more stable and effortless ride". The system has taken three years to develop.  

There's also the Flagbearer system, which uses cameras to read the road ahead and prepare the suspension, and Satellite Aided Transmission, which uses GPS data to preselect the optimum gear for a corner.
