My niece was born on April 1st, I can't wait for her to turn 18 so I can tell her she has £1000+ I've been saving up for years, then give her a card with £20 in it. | |

I am downstairs, my dog is upstairs. I put my coat on to take him to the park, and he charges down the stairs, excited. | |

Probably the noise. Their hearing is a great deal better than ours. Any noise that coat makes, whether it's the zip, you putting your arms in the coat, a combination, it's noise the dog will hear and associate with going for walkies. | |

You could experiment with the dog. Try a different coat, one you very rarely wear, and when you put it on, shake your usual coat slowly so it releases molecules but doesn't make its usual "putting on" sound. | |

Some dogs have been reported (and apparently observed) getting excited when their owner leaves work. In some cases I've even seen the owner claim they leave work at different times. Simple noises like car doors closing are unique, and quite loud. The dog might be able to hear it, even miles away. | |

I'd lean toward hearing. Predators tend to have excellent hearing. | |

If a smell were to move faster than sound, it would cause a sonic boom. Is that what happens when I fart? | |

I intuitively lean towards hearing too. But I have a hard time believing he can hear me putting on my coat from the other end of the house. | |

Here's a floorplan of a house similar to mine. I'm in the kitchen and he's usually in Bedroom 2 when this happens. | |

I don't think there are going to be too many real world examples of smelling something before you can hear it. The particle you're smelling would have to break the sound barrier, not only that but its average speed would need to be >Mach1 from source to nose, so it would need to begin at an even more ridiculous speed to maintain this average. | |

Also, not an expert on fluid dynamics, but I assume that as soon as I pick up the coat, coat molecules start coming off it into the air. There's also presumably some background concentration of coat molecules that I assume he can smell all the time, so he'd have to be noticing the difference in concentration. | |

I guess the other question is whether a coat molecule could travel 40 ft around corners in ~ 10 sec. Seems a bit much. | |

Just to exclude the obvious, you aren't putting on your shoes or picking up your keys or anything similar in this scenario? How punctual are your walks? | |

Yeah I briefly read an article to see what the experts say and it's really not as simple as putting a number on it. There's more to hearing than simple sound. Like you say, frequency is important. Also volume, distance, other sensory distractions, breed of dog... there are a lot of factors. It's just in my experience, dogs have always had ridiculously good hearing, far superior to mine. They'll hear the postman open the gate, car doors closing, dog food tins being opened, things that I would never hear or at least recognise as distinct sounds. I mean, I'd probably hear a car door being slammed shut, but I wouldn't know the difference between my housemate and the neighbour doing it for example. | |

Also if a dog can hear things at x4 the distance, based on the inverse square law that would be 16x better hearing. | |

I just shook the coat and he came. It did make some sound though. | |

Another cool thing about this is he only cares if it's the coat I wear to the park that I put on. If I put on my other coat, nothing. | |

41 gun salute in Plymouth today to honour the Duke. | |

41 gun salute? Is that a thing? I've heard of a 21 gun salute (which is really a 7 gun salute 3 times), but I do not know the symbolic meaning of 21, so ... sure why not 41? But do all 41 guns fire at once, then? (41 is a prime number) | |

Not sure why the old bastard gets a 62 gun salute for his birthday but only a 41 gun salute for his death, but it seems that was indeed the case. | |

Makes me think somewhere in history, someone's gun jammed and so there was 1 fewer shot in the salute, and yada yada yada. | |

This freaked out a load of people in Poland. People didn't open their windows for two days because they were worried it would crawl into their house. Eventually they called the police. | |

I'm pretty sure caterpillars can't get that big, due to the strength of chitin (their exoskeleton) and their internal pressure. | |

NileRed is one of the science YouTube channels I follow, even though I tend to not be a fan of the work of chemistry, I do find it entertaining when someone else is going to the effort of doing all the work. | |

Yeah he seems fairly safety conscious. Still, I saw him sniffing arsenic vapor to see if it really smelled like almonds and I was a bit like "well, I don't care how safe you make it, I wouldn't be doing that." | |

I watch nilered and like his channel, but he definitely comes across as a teacher's pet kind of guy. The way he describes his experiments probably gives his former chemistry teacher a raging hardon. He's very thorough. | |

I thought you said your tinnitus stops for 5sec if you play a tone at the same frequency - that's what i was referring to. | |

I sometimes "hear" a subtle high pitched noise, like a tv is on with no signal, with black screen. Not like white noise static though, it's like a high pitched sine wave. It usually only lasts a few seconds and it's rare. I ignore it, it's not a problem for me. | |

I had something that I feel the "white noise" you guys are describing matches with. It wasn't really a tone, more a deep rushing water sort of sound. It bugged me at first, but then I thought of the short lived high pitched tinnitus that I've experienced and how that's constant for some people-- then I just noticed the sensation, but it didn't bother me. | |

I've actually discovered that if I can mute the 8700 Hz in my head for a second, I hear another, higher pitch above it. | |

I've found when I yawn, I'm super sensitive to some internal noises, such as bass noises I can make with my vocal chords. It's like a door has been opened to my ears. It's really loud and sometimes I can do a flat four beat, and I have my very own techno. | |
