Good God thats scary This dont mean i dont want louder... http://www.stevemeadedesigns.com/board/public/style_emoticons/default/01nocomment8so.gif Just an interesting find Sorry if its a repost
finkster Posted March 29, 2009 Report Posted March 29, 2009 def a repost...however they dont say at what frequency they are at...... and I still dont believe that sound can be measured accuratly enough... how do we actually KNOW that 160 dB on a TL is actually 160 dB? I mean, sure, it can be a reliable device as far as all of the units giving out the same measurements...but i tell ya...sound is some tricky shit...

tacomabanga1986 Posted March 29, 2009 Report Posted March 29, 2009 krakatoa was 228db i think and is the loudest sound ever heard on earth, it was in one of my study books at school, said it was heard all the way to texas and its on the oppiset side of the earth? lol http://www.earlham.edu/~bubbmi/krakatoa.htm here's a link to my system 99 toyota tacoma , 2 mtx 8000 1504's in a sealed downfire , 1000w memphis amp here's a link to my other system my 90 geo prizm test car heres a thread i got of new songs u can dl that are legal = Some Good Bangage/you Can Dl These Free And Legit
Team_DC-Derrick Posted March 29, 2009 Report Posted March 29, 2009 maybe no one is taking in the frequency's at what they are doing, maybe a mower is like 25 hz and the vacuum is like 45hz The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall....... I just realized Steve has reach Voldemort status, over on JP's site he is the one who will not be named....."We dont speak his name over here, fearing it will destroy us" LOL not even in hush tones

tacomabanga1986 Posted March 29, 2009 Report Posted March 29, 2009 ya, and those fire alarms outside of a fire department(warning signal) is around 50htz or so and this will be an opinion but, i know lower tones carry a farther wave lingth, but a higher freq is more audioable to the ear than a lower tone, u can pick up a siren sometimes better than u can an airplane, like a jet flying low can be about 38htz tho, i unno, would be cool for somethin for mythbusters to do? go out and measure ish with a termlab, but ive always wondered this, how do we know a term lab is correct? i mean there has to be something better to set it by? then wouldn't we use that? what was the first db measureing device? and how accureate was it? and somethin can be more louder at a higher freq than it can at a lower one also, like a rock concert is louder due to higher freq's from the guitars(kinda why ur head hearts after listening to rock but not jeezy), but a sub playin 10-30htz just vibrates ish here's a link to my system 99 toyota tacoma , 2 mtx 8000 1504's in a sealed downfire , 1000w memphis amp here's a link to my other system my 90 geo prizm test car heres a thread i got of new songs u can dl that are legal = Some Good Bangage/you Can Dl These Free And Legit
