Sooo whats the difference between that Octane 45 and my original octane 45?.....

8.5" length vs 6.85"
130 db vs 139 db

I think i like the idea of my longer can with less decibels. But i guess Ill only be able to decide for sure after I try one of the K models out...

I just want someone to tell me whether or not the human ear can tell the difference between 130db and 139db.

Without measuring devices, I doubt it.

Do you have a regular Osprey 45 in stock?

Decibels are measured logarithmically, so yes 9 decibel difference is a lot.

 

[Lafsnguy]

Generally people can hear the difference with an increase of around 3 decibels. Like noob said it isn't a straight scale. I have seen it stated that an increase of 10 decibels equates to the noise being twice as loud. So the Octane 45K would be perceived as being almost twice as loud as the regular octane.

 

[JR1572]

Everything I have read states that 9db-10db to the human ear sounds 50% louder.

Take that into account and the lack of an industry standardized "testing" method and the fact that you cannot believe the numbers advertised by every manufacturer, it's very possible that the difference may not be enough for one to hear. I'm sure I cannot tell the difference with my mid-range hearing loss.

Here you go some reading on the subject.

I promise you that most everyone will be able to hear a significant difference between k models and the regular length ones. 2-3 decibles isn't significant but 9-10 is.

I'm sure you're right, but if there is less than a 10db difference between the two, I doubt anyone will be able to tell the difference.

You know just as well as I know that just because a manufacturer makes a claim of a certain level of reduction that doesn't necessarily make it true. Furthermore, there is a nearly endless amount of variables that can change the level of sound reduction.

Given the fact that the published numbers come from the same company using the same sound equipment under the same test parameters and their new numbers are 9db louder (no reason to lie about louder) I personally would choose the "older" model and deal with the extra ~2".

If one wants to defy audible test equipment sound signatures from the same manufacturer, hey it's a free country.
