im going to do that. only because you asked me to listen to you.
im going to leave "MY BUILD LOG" so you and your 18, 19 and 20 year old punk nut ******* buddies can ride each others leg saddle and br "FOLLOWERS"

innovation dont come easily, and progress isnt achieved by doing what others do. I really hope your whole generation isnt stuck on stupid like most of the young kids on this forum.

you are a dumbass, i may be 19...but you have proved to me that i know more then you. And unlike you, i learn from people like PV

I tried using the actual theory to explain, but maybe this blunt approach works better //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

i know... i KNOW. that is why i am saying that it is INACCURATE, because it isnt measuring all the sound pressure from the surrounding speakers creating it and only pulling out the single loudest.

i know that the tl only measures the single greatest frequency

i know there is a rta mode that does full analyzation of the full spectrum

i also know that the tl is a PRESSURE sensor. which only reads pressure.

think about that pressuuuurrr.

your ears read the full spectrum, and we use a pressure sensor because someone figured out how to pull 20 to 80hz out only and make it consitant

when your ears can pull out all the frequencies and the one thing you have to actually tell you what spl you hear is, is from a pressure sensor, the pressure sensor is missing 10s of thousands of frequencies that create an overall soundpressure, maybe thats why a burp is louder than music when your metering, which by law of physics is backwards.even thought the test tone is one frequency maxed out to its peak.

and that is SOUND, 1st

pressure2nd

NOT low frequency pressure, thats what the consistant, yet inaccurate TL reads at.

why arnt there any soundgenerator amplifers anymore by the way?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

i will save the weak minded from reality and stop talking about this matter now.//content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

are you still mad? come on bud. let this crap go. and build. and when you show up next year, or i show up and your there lets have fun. this forum is all about debating. at least thats the way every thread ends up.

I'm not mad man. Just trying to wrap my head around the whole idea. I've re-read literally everything and still see no logic. So ease up there bro, 95% of the shit I say is to just up my post count anyhow //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif.

What the hell do you think SOUND is? Sound is PRESSURE WAVES. They are one in the same. If one pressure wave is stronger than the others, it will overpower them.

Since you seem to be so knowledgeable on the topic, please enlighten us as to how your subs playing at 155 dB and your mids playing at 120 dB will add up to with a "real" spl meter. What would the overall score be?

Go ahead and play pink noise with an RTA going and prepare to be severly disappointed. Odds are you'll start smoking mids and tweeters in the mid 130 dB range.

I'm completely dumbfounded that you're still arguing this when you clearly have no fucking idea what you are talking about.

 

[NoCoSPL 10+ year member]

we are when my buddy gets back from work.sub only

mids only

subs and mids only

then we're testing to see which is louder in the same set up.

the IA 40.1

v.

the hifonics goliath xx

we are testing at 1 ohm, and .25 ohm.

Ia 40.1 ftw //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I think it will be close with in tenths is my bet

sorry. i dont want any problems...

and im thinking the goliath will be louder,

We shall find out when he posts results, but once again ur probably right. . . . James, you testing over at james house?

I hope it's comfy in that magical world of yours, because it looks like you're stuck there permanently. You haven't the faintest idea as to what you're talking. Sound pressure, sound intensity and loudness are NOT the same thing, nor are they interchangable and nor do they have any relationship between one another. You're using the three things as though they are the same thing.
Sound pressure is the dB score that you read on the meter. It measures the SPL level of the car. The SPL level is based on the highest SPL at a given frequency because unless two produced frequencies are close, they will not add together. They only add to make the maximum gain when they are producing the same frequency which is why you do NOT see people using mids and tweeters in competitions along with their subwoofers because they are a complete waste of amplifier power that could be driving larger transducers. This IS how it works, it's not my theory, it is the truth, it's science, it's fundamental to noise control and other fields of engineering acoustics. Reference? The Master Handbook of Acoustics by Alton Everest. I suggest you read it.

Loudness is what you're talking about and is merely a human perception of sound pressure. Midrange frequencies are interpreted as being louder as the ear is naturally attuned with a bandpass response to pick up the middle frequencies at a higher sensitivity than the lower and higher frequencies. This is a fundamental concept of psychoacoustics. Where did I learn this? The Psychology of Hearing by Brian Moore who is a Phd of psychoacoustics.

Sound intensity, in case you're wondering, is the intensity of sound at a given area. It is defined as the integral of one period of a waveform of the sound pressure multiplied by the velocity of the air. The terms intensity and pressure are not the same because in reality, they cannot be derived from one another. Saying "intensity of pressure" is a complete misnomer along the same lines as "the volts of the resistance". This is from the Textbook of Environmental Engineering by P. Venugopala Rao.

I have cited all of my information by professors and doctors of the fields in which they study, and you are citing your own "logic". I wonder who is more accurate?
