The prototype of Rolls-Royce Ghost makes people feel uncomfortable.

However, in a key area, the new ghost is different from the previous ghost. Rolls-Royce has replaced the old steel frame with aluminum structure. This can not only help to reduce the overall weight, but also be combined with other new improvement measures, such as isolating the bulkhead and filling the roof, trunk and floor with more than 200 pounds of sound-absorbing materials, so the interior of the new ghost is almost silent. It turns out that this silence made the early test subjects feel sick.

According to Jon Simms, chief engineer of Bloomberg Rolls-Royce, in the early test of the car's five-year development period, the silence inside the car made these people confused and "disgusting and rude".

Obviously, this is not good for any vehicle, especially those things that are considered super luxurious. How do engineers solve this problem? Simple. They have just found a way to make the car drive louder. For example, engineers develop soft cockpit floor sounds by adjusting the rear seat frame and other trunk components to vibrate at specific low frequencies. They also recalibrated the V 12 engine and chose not to provide revolutionary driving modes, such as sports or track.

Other changes have been made to the sound insulation inside the door, and several layers have been cut from the padded ceiling. Few car manufacturers require the interior of cars to be louder, but Rolls-Royce is not an ordinary brand. It is very interesting how the company will deal with the near-dead situation of the whole power system.

At some point in this decade, the first all-electric Rolls Royce will come out, and engineers will be forced to look for ways to generate indoor noise again.
