I think it's more likely that the faster I go, the less able I am to hear anything. Wind noise is generally measured as 85DbA @ 15mph, but wind noise doubles with a 50% increase in speed, so I'm dealing with ~88DbA @ 22mph.
https://cimg8.ibsrv.net/gimg/bikefor...6a877e8f09.png Cars and trucks are in the 75-85DbA range, so they're simply quieter than the wind. I can't hear the cars because I can only hear the wind. Which is exactly what I've been saying the entire time. Frequency differences matter, so this isn't as neat a relationship as that. I can very distinctly hear car tire noise while riding at 23 mph. I tested that again just last evening. It's at a very different frequency than the wind noise. What's hilarious about this topic is we all have different strategies based on our riding habits, environment and perceptual strengths/weaknesses, and this always degenerates into people trying to prove that their's is the only rational way. BTW, because of reaction times, an additional second of warning is actually quite valuable. |

Firstly, that's not how sound works. If there is a 90DbA sound at point blank range (that is, wind into your ear holes) you cannot hear a 90DbA sound being generated at a distance.

Actually, it doesn't matter if you use the correct units – this statement is simply false. |

Second, if my hearing is already "shot," what difference does it make that I wear headphones? Can't hear the cars anyway. Still manage to put in 10,000 miles a year... and I live on still. I just got back from 10 mile ride next to the freeway. The freeway was 100 yards away from the trail but I can still hear cars at least 200 yards back from my position. I also had cars pass me on side streets and could here them all the way from one light to the next. I can hear the engine, hear the air around them even hear the TIRES for god's sake. That's a quarter mile away. You are definitely either impaired or not reporting or testing accurately here somehow. |
I'm late to the party and I have only read the thread title but I would never listen to music while riding a bicycle. I rely on my hearing for approaching cars, etc.

Cycling is not a pursuit that is limited by a rider's ability to hear. A person with absolutely perfect hearing has no real advantage over someone with poor, or even no hearing. We're not fighter pilots-- we don't need 20/10 vision and otherworldly reflexes. That's just a fact, because I am not extraordinary in any way. Don't need to be. Riding a bike isn't that difficult. Some people seem to choose to make it seem more difficult than it actuallly is. |
I would definitely say not safe you need to hear your surroundings even if on mud track
|
On the multiuse trail it probably is better manners to not use headphones. And it generally is lower noise and more nature so you want more exposure there.
On roadways, I do everything I can to block out the noise of internal combustion engines. |

But like the guy in another thread saying no one needs to wear a mask due to the virus having the wrong info out there can cause problems. I don't wear mask any more because I already had it but I am literally the only person I've seen on a bike wearing one.
I just had an idea, why doesn't someone set up a poll for whether to wear a mask or not? And then another poll for whether to stay home or go out in public. Or would such polls be too political? :fight: |
