SPL-Lab vs Termlab The Truth

[shizzzon 461]

This entire thread covers past, current and future topic to accuracy.

Both companies primary focus is accuracy.

The TL has been the whole dedicated pressure sensor used in competitions and by competitors, etc. for many years without any real credible competition. But is competition possible in this business genre?

Yes! and it's nothing miraculous about it either. Many long-term competitors have put the TL way up on a pedastal because it's always worked. Well, this is how many businesses work from beginning to end.

Toyota wasn't the first automaker but they are doing quite well, Microsoft wasn't the first computer company but look where they are now. Now take that analogy and turn it around and look at what the first of certain companies are doing now in today's world.

Termlab wasn't the first company to develop a measuring device but they are the first to run the most leagues in the world with it. It's so large that it is considered the standard around the world.

Now, what if there were other people in this world, engineers, out of the 7 billion people on this planet to understand the concept and how it works in full. To develop their own line of product to directly compete with this company down to the nitty gritty because that is what we are both about, accuracy.

When SPL-Lab first started in 2007, we had a wired meter that did 120-175db.

Still then, that meter was calibrated to share the same accuracy as the TL using special testing to void out any possible variables that could influence the measured values of either device.

Later on, it was widened to 120-179. Our accuracy measuring methods were to be exact when measuring TEST TONES. Our sampling rate is different than the Termlab so certain rapid peaks in music or averaging in general wasn't dead-on with TL because that would require the same sampling rate.

Later on, we widened our FR range. It has and always has been able to go up to 120hz, higher than the TL has ever done and now SPL-Lab has a range of 10-120hz.

But this still wasn't enough...

In 2013, we are developing the following with before and after comparisons between products-

USB and USB Pro meter-

10-120hz, 110-183dB

Before- rapid sampling rate. Causes unnecessary results in extreme fast measures. Accuracy to TL on test tones is exact. Peaks in music and averaging not exact.

After- Sampling rate has been slowed down to MATCH that of the TL.

Test tones(burps)

Peaks in music

Averaging

ALL will be EXACT to TL once testing is finalized in the upcoming months.

LCD Meter-

20-120hz 120-180dB

Before- slow sampling rate restricted by speed of internal cpu. Sampling rate is 50% slower than TL so requires an additional 0.5sec of measuring time for dead-on accuracy of test tones to TL. Due to the slow sampling rate, peaks in music and averaging will also shift accuracy several tenths of a dB.

After- Sampling rate can now be COMPLETELY bypassed internally by plugging it up to a computer(with new testing software only) and allowing your computer's cpu to do the sampling itself. By doing this, the LCD Meter will share the SAME sampling rate of the TL for Test tones(burps), peaks in music and averaging!

So for portability, you will still retain exact accuracy for burps and very close results to musical peaks and averaging but for utmost accuracy, a computer will now be able to force the LCD Meter to be dead-on accurate for all measuring methods.

Wireless Meter-

20-120hz 120-180dB

Before- Sampling rate was the same as TL on test tones but peaks in music and averaging were slightly off and the dB range was 130-180dB

After- dB range has now been widened to 120-180dB and with new testing software, can be made completely accurate to the TL on-

Test tones(burps)

Peaks in music

Averaging

ALL will be EXACT to TL once testing is finalized in the upcoming months.

This is VERY BIG news for those skeptical of switching from TL or those who are just starting to compete.

What the public is about to see soon is a complete replica of accuracy capabilities no matter the main methods of measuring pressure.

And we haven't even touched on the topic of how modernized our new Testing Judging software is doing

We have developed some features in our very own judging software for leagues that will allow ANYONE to switch over to SPL-Lab if they so choose and those who want to re-invent the wheel on measuring methods for their league classes, we have CUSTOM alteration settings in our software to allow a judge to literally make up exotic classes and measuring tactics that will keep the car audio competition alive for decades and decades with all new and current styles of impressing spectators and competitors alike.

We do not generate exotic preset measuring methods, the limit is all in the creativity of the judge, Why stick with a brick in the wall when there is a road that never ends and the sites just keep getting better.
