Gotta Rant.

First I gotta rant at myself because even though I saw it coming I did not remind AVS people that the Discovery/Science Channel Mythbusters' segment about "The Brown Note" was going to be repeated this week.

Arny, you blew it!

But more to the point, I need to rant about what what a sad sack lame attempt at studying the topic that segment is.

Here are the problems I see:

(1) The equipment used was live sound equipment, and live sound subwoofers generally have one or two less octaves of bass extension than home audio subwoofers
(2) It is far easier to build a strong sound field for bass indoors than outdoors and the Mythbusters did their work outdoors in a parking lot
(3) Much of the time the tones I heard were obviously distorted which means that their energy at fundamental frequencies was reduced or non-existent

These problems actually all fit together. If they had used good home audio gear indoors they would have had cleaner bass as it were.

I've personally done this experiment indoors with mega-sized home audio gear and while I've never seen anybody embarass themselves, I have asked to have the SPL turned down, just in case...

+1. To conduct a valid experiment you have to know what you're doing. They didn't.

Perhaps they should have used these speakers instead:

I like the show because it is entertaining, but I cringe at a lot of their "experiments". It is clear that they are special effects artists first, entertainers second, and scientists/engineers a distant, distant third. Sure beats the usual dreck on TV though.

But arnyk, now people will be able to say... "it's been scientifically proven" to be a myth.
