for your safety, when people hear a car horn, they’re going to be looking for a car.

It should make a ring-ring sound but at 120 decibels?

Ooh, the telephones in the 80s! You should get one of those!

I'm very sceptical of their claims that ~780Hz is in some way special, especially the way they represent it graphically. Playing a frequency sweep while wearing WH-1000XM3 headphones, I don't notice any particular drop-off there. Near where I live, heavy goods vehicles are fitted with reversing indicators that make a "cshh cshh cshh" sound i.e. pulsed white-noise. White noise like that is the hardest for ANC to cance…

On my wh-1000xm2, wh-1000xm3, wf-1000xm4 and lastly wf-1000xm5, there is a quite high frequency pitch (usually coincides with some public transport beeps, and some accidental squeaking of doors) that toggles ANC to transparent mode automatically. I remember reading something about this on Sony's support website.

My XM4's always do that at the beeps from the cash register, although I always attributed that to their volume rather than frequency. My theory was that they refuse to produce sound loud enough to cancel the beeps for safety reasons.

I wonder if you are German? Spending some time in Germany from Holland I notice there is a significant difference in cycling etiquette :) Especially regarding “passing a cyclist” which also touches on the essential difficulty with having only one “ring” sound. Always when Germans pass me on the bike and they ring I get slightly annoyed because I interpret it as a “get out of the way” ring, and I feel like there is en…

As a Dutch person, I experience exactly this dilemma: ringing the bell feels like telling people to get out of the way, when often there is plenty of space for me to pass through, but I know that there's a significant chance that they're going to veer into my way if they don't know I'm coming. Of course, ringing my bell will often cause people to veer into the way, too. But then if you ring at a sufficient distance,…

I used to slightly pull & quickly release a brake lever that made a less-annoying and less-loud "clack" noise when I wanted to be noticed but not to be annoying, generally when I knew I had no right of way but wanted to politely ask for a way around a group of people who hadn't noticed me yet.

Yeah, that's what LLMs do. Now is it true? Who knows!

Overall this bell seems like the wrong solution, and it took me a while to realize not every country has outlawed headphone wearing for bicyclists, something I guess I took for granted. It doesn't make sense for a car driven to use headphones, so not sure why it'd make sense for other vehicle-users to use them either, as you say, we really do use our ears to help navigate traffic so allowing people to be so careless…

You can turn up your car stereo and mow over pedestrians undisturbed in your two ton death machine yet I'm not allowed to cycle on a bicycle-only path with with a podcast and transparency mode enabled? For my own safety? Safety from car drivers that fell asleep driving with their stereo on?

Do horns and bells really prevent accidents? In order for e.g. a horn to work you need enough time that the driver processes the situation and decides the horn will communicate something AND enough time for the pedestrian or whatever to process that and react to it. Generally it's a lot easier just to press the brake, and more importantly be travelling at a speed and in a manner where the brake is sufficient. Structu…

It's not only about preventing accidents (but I do believe it prevents some to attempt answering your question). It's also about signaling to someone that they might be doing something wrong or they might not be paying attention. For pedestrians it takes significantly less time and distance to stop, for cars, trams, and bicycles, it takes longer. It happens all the time that pedestrians don't know the customs of a co…

Phones? I've seen cyclists using laptops. Some of the most oblivious and entitled vehicle operators on the road.

I did that, but I used battery - couldn't figure out how to hook up to the e-bike's 50v electrical system (plus the DC-DC converter with high enough current...) So I am using LiPo 3S, 2200mAh. Works like a charm. I keep it at its storage voltage (3.7-3.8v per cell), and it hardly drained the battery (there is no paracitic drain). Whole thing was like $20.

I pondered doing that but thought it would agitate other road users so decided against.

Some locales are downright itching for a reason to road rage so I don’t blame you. One thing I have to say about being a motorcyclist is that our residents in California are so considerate and have never once mistreated me for beeping, lane splitting/filtering, stalling my bike at a green light, etc.

What if you would rather stay in the bicycle lane instead of terrorizing pedestrians? Quite a lot of taxes were paid for those lanes. Use them, and stay out of my headset.

E.g. in Germany many pedestrians, especially tourists, tend to think that bycicle lanes are fancily-painted sidewalks
