AC to TL?

[mhart]

if i tune my car with an old audiocontrol mic will the loudest tone be the same when i get on a termlab?

[cqtama]

if you mean the tone your loudest at yes it will be the same going from the ac to the tl but your numbers could be a few db off.

alright thanks, i know the TL is lower then an AC, or more accurate, i was worried that if i peak at 54 on the ac it would be different on the tl, since i've never been on a TL and i own an AC.

Prooooobably. But the AC is a microphone whereas the TL is actually a pressure sensor. So sometimes they behave a little bit differently.

yeah mine was a 5 hertz difference.

[mhart]

oh crap, now i am worried again.

The AC mic is prone to variations in atmospheric conditions.

So The AC mic can read peak at a certain frequency when its cold and dry, and another frequency when its hot and humid.

The TL is not affected by atmospheric conditions.

So its hard to tell, The AC could read the same frequency as the TL depending on the weather that day you test, or it could read many hz higher, or lower.

Personally, I wouldnt trust the AC reading.

i can tell you this for sure that the AC meter does read different freqs at higher lvels the AC tends to read a little higher on higher tuned systems and yes the temp thing is true it does red higher when its hot out and lower when its cold

edit don't want to make ya think too much of your next reading
