We Can Finally Do Away with the Accursed Beep-Beep of Heavy Machines

Unfortunately it will take decades for any change to happen to the 100000s of pieces of equipment out there, even in the best case. Under current regs operators can not update the beepers without approval from the manufacturer. It will take a lot of pressure from multiple sources for any change at all.
Any solution that doesn't do an equal or better job will lead to more workplace injuries and deaths. Do we want that?
It's a trade-off. As someone who was around large construction equipment with all those beeps for some time, I would love to have a different solution.
The people who set the requirements (e.g. insurance companies) care about safety effectiveness.
White noise generator / 'broadband alarm':
> White-noise / broadband alarms offer advantages over the typical tonal alarms:
> * Broadcast a range of frequencies making them easier to locate
> * Sound is more confined to those in the area who are most at risk
> * Reduces noise disturbance and noise pollution in surrounding community
> * Are available with adjustable sounds for specific environments

The obvious answer here is to use one type of beeper in quiet environments (e.g. warehouse forklift) and one beeper for loud environment (scrapyard forklift). Of course that opens the door to subjective decisions (the inspector may have to judge whether a beeper is appropriate) and gaming the system (a workplace could run loud machinery at reduced speed) and the vast majority of the people trying to handle workplace safety are coming at it from a perspective where that is a non-starter. You see this any time the subject of "required" PPE and the health and safety implications of it when worn in extreme and non-typical workplaces. People get tied in all sorts of ideological knots when it becomes clear they can't just sling one size fits all solutions at problems.

... which is unfortunate since that there's still a Forbes newsroom (which produce the published magazine editions) which is the only part of Forbes which has actual editorial accountability (and therefore you can lend to Forbes' name).
On the other hand, if the white noise technology lives up to its promises then wow, please actually implement this!
One of my fondest memories of this time was him walking backwards down the hall making the "err err" sound of a bulldozer backing up...
Father and son stand in queue behind obese man. Son says:
- Wow, what a big man!
- Shh, don't say that loudly.
Then man's cell phone got sms, son says:
- Run, he's backing up!I bought a new farm telehandler three or four years ago, and a dairy farmer friend did about the same time. His machine has the reversing alarm which is apparently non-optional. Mine doesn't, and as far as I know, they never sell anything with one.
They're from different manufacturers and mine's centre-pivot whereas his is side-mount, but they're basically similar-sized kit to do the same job. Nonetheless, only one of us makes an enemy of the neighbours at 4am. (I wonder if the rules only require them for construction sites, and my manufacturer doesn't sell into that market whereas his does?)
Missing is the standard for linking these headphones and the myriad of construction equipment to something that calculates distance and warns the listener. So there you go HN entrepreneurs. Write the RFC's, make some prototypes and give them for free to a construction company. Maybe partner with companies that produce the top 10 fork-lifts, skid-steers, tractors, bulldozers, flat-bed trucks and dump trucks as a start. BONUS if you give the workers a way to talk to the driver without having to allocate licensed frequencies.

It's still pretty noticeable, but the ambient noise is already pretty high in the city, so it does fade quickly. Not sure how it would be in a quieter environment, but it's much less annoying than a beep for sure.
The patent should be expired now, so third party companies can finally mass produce these things cheap enough that they can start to appear in new construction and transport equipment.
Such equipment can last decades, though, so even if every truck, bulldozer and crane switches tomorrow, we'll still be in for another 10 or 20 years of beeping at least.
The model ESZ-26B is a Piezo Alert that will operate from 3 to 28 Vdc and can deliver either a continuous or intermittent warning sound. It is usually a simple task to have it wired to the brake lights in most vehicles.
It is available from many vendors. If you need more information, just do a serch for "ESZ-26B".
* Can I hear this white noise thing? I can hear the typical backup beep up close. They're annoyingly loud for people like me. In theory white noise might be audible to more people with partial frequency losses. I don't know in practice.
* Audible measures should never be a sole indicator of danger. Why isn't there a flashing light?
* I can't hear electric cars at low speed at all.
So, LEDs in Christmas/holiday lights are patented?
A person walking in my neighborhood was hit by a speeding cop car. The cop had his flashers on but not his siren. As it turned out in court, the local cops had been getting complaints about sirens being too loud and so had begun operating with only flashers when making basic traffic stops at night. Safety had been sacrificed for convenience, leading quickly to a serious accident.
Are there any studies that quantify this effectiveness?
The time for such debates is before work begins. Complain at the zoning committee that issued the permits for the construction. Demand that your peace and quiet is more important than allowing new construction or a new business in the area. Demand a proper mitigation plan. Demand that they soundproof surrounding buildings. Don't show up mid-construction and ask people to disable the safety alarms.
If I hear machinery 300m away and 20m lower then at this point it is a pure noise pollution with zero benefit to me[0].
And if it can be made less noticeable from far away without damage to safety then it should be done right now.

Making better safety systems is preferable to NIMBYism.

[0] With possible exception for https://en.wikipedia.org/wiki/Bucket-wheel_excavator but I am not convinced that beeping would help if I would manage to miss THAT.
And if I have Bagger 293 in my room then things already went really wrong and weird.
The fire alarm example is a bad one. They don't go off hundreds of times a day for hours on end. If they did, yes, we'd need a different solution.
The construction project across my street has been going on for 6 years. 6 years of beep beep beep beep. There is technology and solutions that serve the same safety purpose but do it better. We can use directional beeper alarms, they can use different noise patterns and frequencies that are more easily blocked by windows and are easier to hear by people near by. They don't need to be as loud, too. There's no reason a backup alarm needs to be audible from 5 blocks in FRONT of the truck when its going BACKWARD.
> Don't show up mid-construction and ask people to disable the safety alarms.
What kind of strawman is this? Folks are asking for better safety code so that future construction can be handled safer with less disturbance. Not asking for a truck on a construction site right now turn off the alarm.
The article also argues that since the current beep travels very far, you hear it all the time on a construction site even if you are not nearby the backing equipment, and thus you start not paying attention to it anymore.
A noise that would fade faster could be safer, because you would hear it less frequently and only when you are actually concerned, making it harder to ignore.
Policy at my workplace demands that all vehicle backing up, including personal cars, honk their horns twice before doing so. I'm sure the neighbors don't like the noise but after more than a couple accidents it was deemed necessary.
So the beepers don't actually even work well enough?
Yes except not all noises are created equal. A white noise is very different from a single frequency noise and much less disturbing. After all many people even use white noise to block other type of aggravating noises.
Here in Montréal all snow removal vehicles are equipped with a white noise backup alarm. It's snowing a lot in winter, so you have huge snow plows that might back up at any time in the middle of an intersection with pedestrians with earphones not paying attention, and I can say first hand that you cannot miss that noise when it's nearby. While at the same time when they are removing snow one block away from my place, you can still hear it but it doesn't prevent you from sleeping.
This type of backing alarm has been approved as safe on construction sites by many places. In Canada at least its very commonly used. e.g: https://www.heavyequipmentguide.ca/article/24957/backup-alar...
From the article:
"Those who first mandated the beep thought it was good that it was annoying and impossible to ignore — and thus went for a distance. Because it "travels" like this, on any construction site (or near one) you are hearing them all the time. You become used to them and even start to ignore them, and that is why people still get crushed."
The argument isn't about removing the sound but making it less intrusive and more effective at its job. Even in your example of police sirens there was a recent study posted on HN which concluded that loud emergency vehicle sirens causes panic in motorists leading them to make poor snap decisions resulting in accidents.
I don't even work in construction, but I hear these so often every day, day after day, that if there's one coming up behind me, I'll likely get hit. The only way I can live my day to day is by having trained myself to ignore them. It's really useless as a safety measure. I know at least one person (elderly family friend who had perfect hearing) who got squashed by a large truck because she was in the same situation. Didn't bat an eye at the beeping right behind her until it was too late.
The beep is for safety. The annoyingness makes it hard to ignore which is good for safety.
Anything that tries to replace it needs to keep safety up. It can't be easy to ignore. I can't require headphones on a person (what if the battery dies after 8 hours and they are working a 12 hour shift... or any number of other things).
So many organizations are pushing safety. Governments who want to protect people. Insurance companies who don't want to pay the cost (and put requirements on construction companies). And people who don't want to die or get maimed.
A patent on an idea doesn't mean it works to get people to notice who have been around the equipment for 3 or 6 or more months. I would love to see some research on it.
That annoying beep works well so it's hard to replace.
