    I just bough my SPL, but I bought the digital, and I have seen that many use the analog, do you think both operate the same, or should I return it and get the analog?

    Thanks

    I thought the analog popularity was the ease of reading an analog gauge during minor fluctuations. I could be wrong...

    I thought it was just because it cost half as much.

    Problem is where I am, they don't get the analog anymore, only the digital, so I had no choice.

    Same thing here. Just the digital. I bet they make more?

    The digital is easier to use for quick, precise measuring (you see a number instead of a +/- level) and it's also more accurate- mostly because the analog needle isn't quite as fast as it needs to be. Digital is also supposedly more reliable, as there's no needle to break. (this info is second hand, from a pro sound web page, btw, but I trust it.)

    That said, analog meters are easier to see peaks on from across the room; but if you are going through the trouble of buying an SPL meter you should either have a friend help you take measurments, or conduct your tests in such a way that you can be at the meter.

    BTW, make sure to hold the meter at arm's length, or on a tripod if you have one.

    And yes, you should use C-weighing. it's about -8.5 dB @20Hz, IIRC, while A-weighing is significantly more.

    Neil- that chart is for C weighing, right?
