[Quietcars] Quiet vehicle warning sounds

[michael townsend]

Bob this is good, but I think that this is the noise when the car is moving
up to a certain speed; am I correct on this? 


American car manufacturers have done little to employ techynology or
enginuity to this problem. It is far easier to get a law passed than to
implement it as we shall be seeing.  Nissan, 
Tesla and Lotus have been working on this, and 
Volvo has a pedestrian safety system that brakes the car when it sees
pedestrians  
Chevy 
Volt's system is driver negotiable, but I think that the 
Ford 
Focus electric which is coming out, has some warning systems built in.  

However on a different note altogether, the hybrid offerings from 
Ford like the 
Escape and 
Fusion, are being phased out since they are less than steller sellers.

 


There are no new sins; the old ones just get more publicity.

Narated in Japanese, this U-tube recording includes the Prius pedestrian
noise generator in Japan:

My understanding is the noise generator is optional in Japan.

looking for technical information on the synthetic sound sources
manufacturers have developed for quiet vehicles. I was hoping you could
direct me to some technical specifications about synthetic sound sources for
silent or nearly silent vehicles.
