Well I searched the net and can find nothing *bored obviously* comparing a normal mic with the TL. I have read the Termlab benefits and quite frankly don't agree with them. Their slamming of mics leaves out one important piece of information, the word measurement. A good measurement mic will NOT drift over time, with humidity, with large SPL swings and such. The mic that I use with my spectrum analyzer will stay within .1dB in all of those instances.

That and it looks like the TL is a pressure sensor which are typically 1% of FS accuracy, which is no where near a good mic. Do you guys know of any links comparing the two technologies that support the TL? The only TL benefit I see is cost.

Depending on your definition of a "diaphragm" measurement mics don't really have one. Basically a hermetic welded membrane that acts as a capacitor.

I hadn't actually thought about ever using a TL since I have a full blown spectrum analyzer, but am just curious as to why it is being used in competitions when a mike is a much better more repeatable device, albeit a lot more expensive but nonetheless.

I do realize that above 180dB you have to switch from a mic to a hydrophone (~$6k) but again it is then a real direct measurement instead of some applied thing.

The TL site isn't very helpful at unveiling what they are doing and I keep seeing scores from TL measurements and am just wondering what they equate to.

I know you say that the mic is a more repetitive devise, but I have seen 100's of times where it isnt in SPL. Most of the AC mics (180 and down) werent accurate, they would give you different numbers every time. With the TL it will average the 3 loudest notes and 99% of the time you will get the same score if all things are the same (voltage, amperage, blah, blah....)

Plus I have seen people go from 1 AC mic hitting a 150 lets say, then switch to another and hit 155...With the TL they are all calibrated to the exact same specs per instical. This keeps the numbers very consecutive.

In that range a standard measurement mic will be repeatable to within .1dB; AC's are not that great though. I check my mics calibration at least once a year and over the past 5 years it hasn't drifted .05dB even.
