Early Rolls-Royce Ghost prototypes made people feel nauseous

The Ghost was made so quiet, Rolls-Royce actually had to inject sound back into the cabin to keep occupants sane.

The second-generation of Rolls-Royce Ghost was released earlier this year, and it features some pretty incredible noise-insulation technology. As we noted earlier, every minor acoustic detail inside the cabin was perfected to the minutest detail, down to the buzz of interior components tuned at specific frequencies to create a serene atmosphere.

To give you an example of this detail, the sound of wind coming out of air conditioning vents was unacceptable, so the entire climate control system was removed and completely redesigned to keep sound at what Rolls-Royce expected was an acceptable level. Further enhancements included modifying drivetrain and other mechanical components in order to reduce the car’s sound level.

Unfortunately for the engineers – like most things in life, this heavy reduction in sound came with downsides. During early testing, occupants of pre-production Ghosts were getting sick from the silence achieved in the cabin.

Yes, thats right – the car was so quiet, people were getting nauseous and disoriented from merely sitting in it.

Consequently, after all the noise insulation techniques were employed, the engineers needed to further develop/un-develop the interior by artificially injecting some noise back into cabin. Thus, new soft undertones were made present by vibrating the rear seat frames and some components in the luggage compartment at a specifically set low frequency.

Additionally, a few layers of padding was removed from the headliner, and the insulation inside the doors were redesigned to make the car’s road noise louder.

This process really demonstrates how much dedication Rolls-Royce puts into research and development, and it shows that there’s a reason cars carrying the Spirit of Ecstacy badge are so iconic.
