SOUND OF SILENCE
An incredible amount of science has been devoted to making the new Phantom the most silent car in the world. There is a six-mm two-layer glazing all around the car, more than 130 kg sound insulation and the largest-ever cast aluminium joints in a body-in-white for better sound insulation. Highabsorption materials are used. Acoustic insulation
from road noise has been helped by double skin alloy on areas within the floor and bulkhead of the spaceframe. Noise insulation has also been done by inserting dense foam and felt layers between these skins.
High absorption layers within the headliner and in the doors and boot cavity have further aided insulation and reduced reverberation. Rolls-Royce also worked closely with its tyre supplier to invent ‘SilentSeal’ tyres; a foam layer is placed inside the tyre to wipe out cavity noise and reduce overall tyre noise by 9db, which means effortless conversation within the car. These have made the car approximately 10 per cent quieter than its predecessor at 100kmph.
