In potentially-dangerous-animal country (e.g. grizzly bears, mountain lions, etc), it could be a safety mechanism...I was told repeatedly you need to make some kind of distinctive noise regularly so they won't get startled by you rounding a bend.

[chasd00]

those people, i've encountered them too, don't give a shit about anything let alone being safe around wildlife. If prey distress calls could be confused with music they'd be blaring that just as well.

That's what "bear bells" are for...in bear country.

Mountain lions are avoidant at all times unless it's a mother with cubs and even then they'll let you know well in advance.

Otherwise, just normal conversation, your smell with even a light breeze, and the vibrations on-trail will alert all animals to your presence.

In other words, the "trail music" theory is bullshit. They just want to listen to their music.

> Mountain lions are avoidant at all times

Actually sometimes they stalk people but I guess that's neither here nor there because bear bells aren't going to help in that situation.

[chickensong]

Bear bells have been shown to not be effective.

[m463]

lol.

that's like harley riders with unmuffled motors "for safety".

On the other hand, I remember being in japan and watching some construction vehicles in tokyo. They were surprisingly quiet. After a while I realized what it was - in the united states all construction vehicles have these annoying "beep-beep-beep" sounds while they're working (for safety).

I wonder if one day they can play those only when someone walks nearby or play in some technologically quieter way.

In France I see (and hear) more and more use of a special type of warning device, "le cri de lynx" that reduces sonic pollution by building sites.

> while they're working (for safety).

Should only be while they're backing up. It signals to anyone around that the vehicle is in reverse. At least the ones I'm familiar with.

> some technologically quieter way.

I'm not going to watch the video linked in sibling comments right now, but "pulsing loud static" is a pretty common alternative to beeping around me; especially in the big citie. Kind of a big shush shush noise: sometimes it sounds a little like hydraulics working which is fine because if you hear those, something big is happening and you should pay attention.

Anyway, the real nice thing is it's loud and attention catching near the source, but it seems to disipate faster than beeps, so you don't really hear it when it's not relevant.

[throw-the-towel]

These people probably don't do it for this reason, but you're correct, at least when it comes to bears.

[mrexroad]

Huh? I’ve never met anyone in the backcountry that played music to keep predators away. Even when forced to hike at dusk, the primary risk is quietly stumbling on a predator out stalking, or worse, a predator’s offspring. At most you clap every so often, maybe talk/sing to yourself, or dangle some stuff from your pack at higher risk times. Animals will do the hard work of avoiding you When you’re nearby, but its quite unnecessary to notify everything with in a 1km radius of your presence.

This is my reason for blasting music from my bicycle. Feels less rude than clicking a bell at the pedestrians and somewhat more effective at attracting attention.

[VorpalWay]

That is definitely the wrong thing to do. It isn't rude to use the bell, and as a pedestrian I appreciate a single ring (obviously, don't ring like a madman either). Playing music loudly in a public space is way more rude than using your bicycle bell.

[cwillu]

It's great for announcing that an asshole is approaching.

[lostlogin]

Better still, a nice free hub. If you don’t pedal, it’s noisy, if you back pedal it sounds urgent.

As an upside, your better get good at hill climbing as freewheeling or backpedaling up hill takes some practice.

[nephihaha]

We don't have bears or mountain lions where I live but mountain bikers still do this.

[what]

How about don’t ride on the sidewalk or any pedestrian path.

It's amazing how HN readers are immune to second degree and fell flat into the trap.
