Hey Brian, How about letting drivers customize the sound, as I blogged about here (http://www.examiner.com/article/hey-you-loser) a couple of years ago.

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.

(Oop, one too many "not"s in there: "... that they make recommendations not specific to...")

Glass packs on a big block Chevy. Or much easier, just get rid of EVs and hybrids.

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.

Yes!!! You hit the nail on the head – my thoughts exactly! We can hack the car and install the Clipity Clop (or whatever) sound so “Blind” people will know WHO is approaching – by the sound.

The sound of 2 coconut halves clip-clopping might be better.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
