![]() ![]() ![]() ![]() Today we’re going to apply it to whole words in a text. So, yes, very loud, but not quite “destroying the galaxy” loud.Ī final note: since the current world record for loudest barking group of dogs is a more modest 124 dB from group of just 76 dogs, if you could get a million dogs to bark in unison you’d definitely set a new world record! But, considering that you’d end up hurting the dogs’ hearing (and having to scoop all that poop) I’m afraid I really can’t recommend it.Ī Markov Chain is a type of simple (but surprisingly powerful) statistical model that tells you, given the item you’re currently on, what item you’re likely to see next. We’re talking about the loudness of a cannon, or a rocket launch from 100 meters away. That’s loud enough to cause hearing loss in our puppies and everyone in hearing distance. Now, to put this in perspective, that’s still pretty durn loud. But it’s sixty decibels louder than our original sound of 113dB, for a grand total of 173dB. (If you want more math try this site.) The base ten log of one million is six, so times ten that’s sixty decibels. If we want a bark that is one million times as powerful (assuming that we can get a million dogs to bark as one) then we need to take the base ten log of one million and multiply it by ten (that’s the deci part of decibel). Ok, so we know what one wrong approach is, but what’s the right one? Well, we have our base bark at 113 dB. We wouldn’t be able to get a bark that loud even if we covered every inch of earth with clones of champion barker Charlie. A sound of 1000 dB would be loud enough to create a black hole larger than the galaxy. For reference, under normal conditions the loudest possible sound (on Earth) is 194 dB. This means that a 1130 dB is absolutely ridiculously loud. Why? Because the dB scale is logarithmic. Unfortunately, if you took this approach you’d be (if you’ll excuse the expression) barking up the wrong tree. (I’m going to use copies of Charlie and assume they’ll bark in phase becuase it makes the math simpler.) One Charlie is 113 dB, so your first instinct may be to multiply that by ten and end up 1130 dB. Now, let’s scale our problem down a bit and figure out how loud it would be if ten Charlies barked together. (Interestingly, the loudest recorded human scream was 129 dB, so it looks like Charlie’s got some training to do to catch up!) That’s louder than a chain saw, and loud enough to cause hearing damage if you heard it consonantly. The loudest recorded dog bark clocked in at 113.1 dB, and was produced by a golden retriever named Charlie. So, first off, we need to establish our baseline. This is an interesting question because it gets at some interesting properties of how sound work, in particular the decibel scale. So a friend of mine who’s a reference librarian (and has a gaming YouTube channel you should check out) recently got an interesting question: how loud would a million dogs barking be?Īlright now, all together on the count of three… are you even listening? ![]()
