July 11, 2009: WOOF @ 108db

Daz, the world's loudest dog, barks his way into the Guinness World of Records.

My dog can only bark at 107 db. I guess that makes him a sub-woofer.

Perhaps I am confused but that doesn't look like a bungalow to me.

For comparison, 107 decibels is roughly equal to standing 3 feet from a power mower. That's a loud ass dog.

loud and pretty! white german shepherd!

Pooka LOL'd at ZenGum. And now, an 110db burp:

that dog looks just like Pocky

Acoustic power is measurably doubled at exactly 33.3~% intervals from human hearing? What an amazing coincidence.

That's what they say. To be honest, I don't know much about that area of things because it's live performance stuff. I don't care how much power something generates, I only care what it sounds like coming out of your computer or game system.

Not sure where you came up with the 33.3% figure -- decibels measure a ratio on a logarithmic scale:

db = 10 x log (A/B)

for a doubling of power, A/B=2, so

10 x log(2) = 3.010299

which is almost always rounded off, hence "3 db"

Right, all of which is acoustic power, which is different than what it actually sounds like to your ears. The audible scale is logarithmic as well, but the doubling interval is 10 db.

Is the db used for audible hearing the same unit of measurement used for acoustic power? If so, then I maintain that it is an incredible coincidnce that an exact doubling of two unrelated attributes is acheived at intervals of roughly round numbers. That is, unless either the attributes or the unit of measurement has been rigged to produce this result.

It's only cool insomuch as they're both logarithmic scales and logs can do some pretty funky stuff in math. They don't actually keep pace with each other or anything when you look at them. As for whether the even numbers are a coincidence, I'm pretty sure the unit was designed with the 10 db = doubled hearing level calculation in mind. I think the 3 dB being so close to a round number is the coincidence.
