Powered by a high pressure hydrogen fuel cell, the Emissions Neutral Vehicle produces the equivalent noise of a personal computer fan belt.I think the complaints about a lack of noise being dangerous are largely hogwash. Riders who favor "loud pipes" claim car drivers won't notice them unless they blast their ear-splitting exhaust systems at full volume. Maybe that helps, but you shouldn't be depending on noise to keep you safe.
Not only is that distinctly wimpy in the eyes of many bikers, it could also be dangerous.
Intelligent Energy...is looking at ways to produce an artificial engine noise that will alert people to its presence, making sure the machine is not silent and deadly.
The truth is that the deep rumble of an internal-combustion engine is just part of the motorcycle experience, plain and simple. As British Motorcycle Federation spokesman Jeff Stone explains later in the Reuters article:
The motorcycle is a primitive thing and it appeals to the inner person. The excitement and exhilaration of a bike is why people ride them.Reuters notes that the designers are thinking about adding a fake engine sound to make the ENV noisier, but that would be about as effective as replacing a dog with a stuffed animal and a tape of barking. The charm of a motorcycle is that its noise comes from the physical interaction of dozens of metal parts and pieces, right under your seat. In our increasingly virtual world, a bike’s noise, smell, and vibration are proof of something tangible and real.
