Cor,
While you cite an example where the sound is a "small hiss", the article
refers to it as an "alert sound". That could mean just about anything. I
think it's important that this sound be reasonable for all parties. I
also agree that it should apply to all quiet vehicles, not just hybrids
and EVs.

Hi Thos,
Yep, early Leafs have noise maker that can be canceled (but just like
the communication warning, returns after the next time starting).
I believe this was so that the vehicle can be sold in countries where a
noise maker is allowed (or required) but needs to be muted at night.
The blind person argument you describe is set in dead silence, the city
street situation is set in a surrounding with a lot of other noises
masking the quiet sound of slow rolling tires.
There are plenty reports about this and while it is possible for an
attentive person in a quiet street to hear all traffic approaching (I
actually rely on this when I am riding my bike) it is not possible to
depend on this in noisier environments and that is where the noise
maker comes in.
Note that the noise maker is not making a lot of noise, it is not your
neighborhood jacked pickup truck that everybody recognises from waking
them while they sleep, it is just a small hiss as if the tire has a
leak. It does not penetrate a wall, unlike the sound of a straight
pipe.

As I recall, the 2011 Nissan Leaf that we had made a Jetson spaceship
type
of sound at low speeds. Not very loud or obnoxious, but definitely not
sound that was produced by the drive train. I asked the dealership
about
it, and was told that it was a voluntary action in a proactive effort
by
Nissan, expecting such requirements at some point in the future.
By the way, I find the blind argument offensive...I grew up with 2
blind
friends. They could tell you how fast a bicycle was approaching, let
alone
a car just from the tire noise...It is the pedestrian blinded by
electronics technology that we need to concern ourselves with!

I imagine with horror a city full of cars emitting 1khz square wave
beeps,
like so many commercial trucks and construction equipment. I can
barely
tolerate hearing those. Add to that and I will go crazy. I'm sure I'm
not
alone.
Now, I don't expect the rulings to call for something that obnoxious.
But
still, without some pushback, we may increase the amount of noise
from our
current levels. That would be bad, in my opinion.

The US government on Monday completed long-delayed rules that will
require
"quiet cars" like electric vehicles and hybrids to emit alert sounds
at
speeds of up to 18.6 miles per hour (30 km/h) to help prevent
injuries
among pedestrians, cyclists and the blind.
The rules, which were required by Congress, will require car makers
like
Tesla, Nissan and Toyota to add alert sounds to all vehicles by
September
2019.
