I admit I have not looked into this.
If the sound is coming from the module, and the speaker is just a speaker, then there is a chip on the module board that is the source of the sound generation.
Someone with the time and know how should be able to pull that chip, read it, program another chip, but using the jetson sound, my personal preference, and reinstall it.

Any takers?

I'm not sure if this sound is required by a federal or particular state law, but if it is, disabling or modifying it may be illegal, not that you'd ever get a ticket for it. But, if it is illegal to modify the sound, and if you were to hit a pedestrian, and if they found out you modified it, you could be liable to that person for his injuries.

For the record, I'd also vote for the Jetson sound. Or maybe the theme from Shaft. :lol:

Despite the warning noise I still get people stepping out in front of me, especially in parking lots. I think they may hear it but not recognize it as an approaching car. I've even had a pedestrian run into me!

There is no legal requirement for this sound yet. It's been proposed but I'm not sure what that status of this legislation was and if and when it takes effect. The sound Nissan picked and its other parameters were their decision. Other EVs solved the problem differently or don't offer a warning sound at all. As I said before, there are other threads with more substational information about the VSP. This thread was resurrected by a new forum member because he could not find anything better. There is even a post by Ingineer describing the chip used by the sound synthesizer and how to program it. All this takes is a little bit of time and effort.

Yesterday in the grocery store parking lot, I'd shifted into Reverse gear (dinging sound is activated) and still couldn't get the attention of the doofus couple who'd, seconds later, blocked my right rear quarter panel with their grocery cart to unload into the car on my right. I sat there, car dinging and waiting, waiting and dinging, waiting...until I finally had to drop my right rear window and politely ask them if I was clear - then the guy's brain activated and he moved his cart out of the way (duh). They'd arrived behind my car just as I'd shifted into Reverse and they were ogling her, so it should have been obvious with my reverse lights on and the dinging that I was trying to leave (there was even eye contact with the guy as I looked over my shoulder). Reverse lights & sound alerts don't necessarily equate to intelligent reception! :roll:

The article doesn't mention any ability to select which engine sound you would like, but the MUTE capability might be useful.

You want other Leaf owners to hate your Leaf, too?
