Noise requirement?

[sodamo]

I’m sure space utilization is the excuse. If the spaces get any smaller noone will be able to exit vehicle.
Back in parking only with 3 ft corridor between rears. Can you imagine that fiasco until people learned how to back in?

 

[Paul Rodgers]

I agree! It's really not even hard, just takes more space and space costs money so they need incentive to do it.

I do no think it would take "more space". I believe I can design a parking lot that can hold just as many cars, but the local zoning board would not allow it
2 main reasons:

1) there would be no "main drag" in front of the store. pedestrians only, cars in the back of the lot
local zoning would run screaming into the wind at this idea, for no valid reason.

2) EVERY parking-bay-corridor will have a pedestrian walkway, everyone parks tail-in to this corridor
- If you cant do tail-in-parking, DO NOT SHOP HERE, you are not competent to drive.
- if you insist on head-in-parking, OK, but if you get clipped by a car, when loading the trunk, you are at fault.

Now, point-1 would get most folk really fired up, not sure why, but however since COVID most big-box stores have a pickup location, solves that one hmm?

Point-2 is a bit trickier,
If you cannot back into a parking stall? Most newer cars have cameras, sensors, beep at you all the time!
Well, maybe you should just go to the pickup-location that I talked about in point-1?
Or in my case, old fart, just park way out in the back-40

And lastly, more trees please, really, why is it so hard to find shade at a Walmart?

SO, your digging a ditch, loading it into a truck, the entire neighborhood has their Sunday ruined by your beeping. And this is NOT a quiet vehicle either.

But no, seriously, why do you want to annoy pedestrians?

White Noise > Beeping sounds

White noise is far less annoying and it improves ability to locate the vehicle.

From a distance white noise blends in with other noises, so it creates less noise pollution too.

Dude! beeping at 108 decibels is NOT white noise
Its audible, and annoying from a mile away!

Hey! this is not trouble!
Its just a "vociferous debate", thats what my mum used to call it when my brothers and I would argue a point. That was usually motorcycles, then we grew up and it became politics.

An animated debate, no matter how you rate it, or any of the participants, is better than a war.

Bottom line: get your kids in here, we want their feedback!

That's the whole point of what I wrote.

White noise is an alternative to beeping that's more effective from nearby and not annoying from a distance.

OK, I get that, but white noise will not get your attention.
The point of the horrible beeping is to make you pay attention, to the horrible bucket-loader, 400 yards away, past 4 houses, and 7 fences.

How loud do you suggest the white-noise generator be for reverse on a bucket-loader?

To be effective, for a pedestrian within say 25 yards, if would need to be loud enough to deafen the operator, permanently. All those folk already wear noise-cancelling headsets, as self-protection, anyway.

 

[AZFox]

OK, I get that, but white noise will not get your attention.

It's quite the opposite.

I'll let an AI explain...

White noise is considered better than beeping for reverse alarms for several reasons. Firstly, white noise is more directional, allowing individuals to easily determine the source and direction of the sound, which is crucial for safety.​

​

This is in contrast to the traditional beeping sound, which can be difficult to locate, especially in noisy environments.​

​

Additionally, white noise is less intrusive and less likely to cause noise pollution, making it more suitable for use in residential areas and other noise-sensitive environments.​

​

The white noise sound also has a broader frequency range, which can be more effectively heard by people with hearing difficulties or those wearing hearing protection.​

​

Furthermore, studies have shown that white noise can be more effective in alerting people to the presence of a reversing vehicle, as the human brain finds it easier to determine the direction and distance of the sound.​

​

Overall, white noise reverse alarms offer a balance between safety and noise reduction, making them a preferred choice in many situations.​

Edit: For these reasons some European countries have bans or restrictions on traditional beeping reversing alarms in favor of white noise alternatives.

Paul
Locally, I can’t think of major store whose pick up area isn’t just a handful of close parking spaces, acerbating the situation, but I like your concept.

 

[sodamo]

I don’t think we want or need the super disturbing commercial backup type..
Maybe something more personally annoying in a small area, “watch your butt, Please” in a sarcastic tone.

When I started this thread, I had no idea I was starting so much trouble!

This subject is a pet peeve of mine. Until recently I kept an office in a small town in a rural county (think Mainstreet USA) with low ambient noise. And I grew up in a medium-sized metro city and lived on the weekends in New York city when my GF (now wife) lived there.

My observation is most of the noise that comes from cars is tire noise and aerodynamic noise. With any level of ambient noise in a city or even QUIET small town, any car travelling 20 MPH or over makes tire and wind noise that far overcomes any level of (legal) exhaust noise from a plain jane street car. And most all ICEV exhaust at the rear of the vehicle, so any exhaust noise is heading away from a pedestrian in front of the vehicle. The whole concept that EV are quite and need noise generators for pedestrian safety is just completely stupid IMO.

 

[AZFox]

Tire noise varies by a LOT. Here's how I know...

I had a Mustang Convertible and read somewhere that getting quiet tires was the shiz-nit for convertibles.

I upgraded the Mustang's wheels and put some Yokohama "Decibel dB" tires on the car that were specifically engineered for low noise.

Wow! What a difference.

I couldn't hear any noise from the tires during normal driving (except they squealed in parking garages, which was kinda odd). It was especially strange to hear only noise from the other cars on the freeway when the top was down.

I've been paying attention to Tire Noise Ratings ever since.

I would pay a THOUSAND DOLLARS for my Slate to make this sound.

QUIET. Forum spelling NAZI here. Total agreement though.
