The whole point of demanding that cars make some sound is so that they are identified as cars. Custom sounds as in custom ringtones would totally thwart that concept. What EVs need to sound like is those early inverter drive forklift trucks. A sound like no other, not obtrusive but a bit scary
It's bad enough having to listen to all the ridiculous ringtones at work. I surely wouldn't want to hear a constant barrage of random sounds from vehicles. There would always be the small percentage of people who would have to get stupid and try spoken phrases, sirens, chickens, etc. As long as there are humans involved, it has to be strictly controlled.
I have a serious comment that I'd like to send to this National Highway Transportation Safety Administration study. Do you know how I can submit such feedback to them?
In particular, I want to recommend to them that they not make recommendations not specific to EVs or hybrids, but to any vehicles that make less than so-and-so much sound volume at low speed, regardless of why that may be the case.
I'd start here... (http://www.nhtsa.gov/About+NHTSA/Press+Releases/DOT+Proposes+New+Minimum+Sound+Requirements+for+Hybrid+and+Electric+Vehicles)... There is at least a contact atop the release.
But more likely is the Federal Register: https://www.federalregister.gov/.
Let us know what you find out!
The syncopated clops of horse shoes hitting the ground. At 4 mph and below the gait would be a walk. At speeds from 5 mph to 10 mph the sound should transition to a trot. From 10 mph to 17 mph it should be a canter, and speeds from 18 mph to 30 mph the sound should be a gallop. In this way, sight-impaired people will know how fast a vehicle is approaching so they can adjust accordingly.
