Sound is required by the law of physics to ADD UP, just like adding any other measureable propertys. i guess measuring a 1/2in and 3/4 inch gives you a 3/4 because 3/4 is bigger?

or a gallon of milk + a gallon of water = a gallon of milk because the milk is dense?.

a harley drives by with screaming *** pipes and bus roars by, oh,i didnt even hear that harley because the bus was so loud.

you are talking about completely different properties here.. sound is in waves.. meaning it won't all just add up.. some will cancel some will add.. simple.. others won't even meet.. its not the same as adding wood pieces up or milk and water.... and with the bus and harley its variables.. how close one is interference etc..

just becasuse it is used does not mean it is accurate.

ya I am sure they wouldn't ever think of changing things up if they might be wrong..

WHOOOOOA THIS IS MY BUILD LOG:wow:
AND im not arguing, just stating the facts about accuracy and pointing out the faults of "An ELECTRICAL DEVICE" i guess we will keep the term lab forever because "NO ONE will ever figure out how to add two frequencies together and come up with an accurate number."

tell that to tesla when he invented AC and replaced DC as the main power source.//content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

like I said before frequencies don't add up with other frequencies unless there waves interact..

nobody is talking about wiring subs outta phase, THAT WOULD BE CANCELATION OF SOUND. ONE SUB + ONE SUB EQUALS MORE SPL

2 SUBS + 4 MIDS AND 4 TWEETS = MORE SPL

YOUR THEORY: it appears i actually have to put "FOR EXAMPLE"

IF:

1 SUB = 130DB

then

1 sub + 16 mids and 16 tweeters STILL = 130DB

GOOD JOB DIQ HEAD

Like said before.. different frequencies... You can make something to measure higher but thats not what we are going for in spl..

Dude, are you STILL arguing this? I thought we went over this ad nauseum in that other thread.
Every single spl meter in the history of spl meters will only measure the SINGLE LOUDEST FREQUENCY. NO ADDING. NO MATH. NO FORMULAS. END OF DISCUSSION. QUIT BEING SUCH A FAGGY DOUCHEROCKET.

this.. Even if it wasn't this they don't ADD up

PS@PV: Waves of different frequencies do add, only at the point at which they do line up. Play with just something like Fruity Loops with a sine wave generator and you'll see that it will equal 2A, but not for long enough or often enough to matter or effect the measurement, is what you're saying. Also, when adding two different level sounds, the one of the lower level would have to follow the logarithmic operation. Ie 3dB = 2x as loud, 6dB is 4x as loud, 9dB is 8x as loud, so on and so forth. So essentially lower volume waves would not effect it as much either way. Mathematically, adding sound pressure would be given by 10log(10^(L1/10)+10^(L2/10)+10^(Ln/10)). Ln is measured in Pa.

Thank you, I love learning new things //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I think I will sig that //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Do it, and also post this in there as well before you think it's a stupid statement:

Loudness, a subjective measure, is often confused with objective measures of sound pressure such as decibels or sound intensity.

http://en.wikipedia.org/wiki/Loudness

You know what I meant anyway. You cannot measure loudness because it's entirely dependent on a person's ears. Higher sound pressure does induce a higher perception of loudness, but there is no relationship between the two. Relationship is used to mean mathematical relationship, so just add the word mathematical to make it more accurate.

Ya I gotcha.. I added it nonetheless

so you got all your facts from wikipedia???? and I thought you were smart:crap:

I personaly think McIntosh was worse:crap:
This guy just seems to be shootin up Ultracet:veryhapp:

Well, at least this concept is a bit harder to understand than the concept of a wire can carry an infinite amount of current, though it will create heat with a proportionality of current squared multiplied by resistance. (I^2R) Then apply this amount of energy to heat capacity equations and you'll find how much it will heat per second etc etc.

On second thought, I think McIntosh was worse. Yep.

Yep, just learned about this in school we use this to caluculate the amount of light and heat in an electrical arc flash in calories. I^2R we use for heat loss in electrical circuits,and motors too. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Makeshift knows his shit. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

James,

You should wait and test with the SD16k as well. IIRC, those are full range amps and can play the full Khz spectrum.

ohms law is great. so was electronic repair when i took it.

 

[Nismofreak 10+ year member]

lol. Just noticed this

for the 1 million $, finish that phrase, " uh... i dont think i should say it" go ahead tom, finish that puzzle. "N!GGERS.." BUZZZZZZ, wrong....

"OOOOHHH, NAGGERS"....

lol i guess you mean me haha

You could always design a device to accurately measure your subs plus mids/highs to prove your theory. then go one step further and start an org that competes that way....
