    PS -- youse guyses do know the difference between pink and white noise, yes?

    White noise: Equivalent power level across any band segment

    Pink noise: 3 dB falloff per octave
    "every octave contains the same amount of energy", as Wiki-P puts it (which is fitting given the way we hear sound)

    I would argue that the .5dB step is a lot closer to a .5dB increase/decrease in volume than it is to a 3dB increase/decrease.

    stumbled across this ol' sticky @ AK (looking for something else):

    If I'm not mistaken, .5 db is roughly 16% louder, 1db is roughly 33% louder.. that's somewhat of a large percentage even though its expressed in a small decimal.

    and 10 dB = twice as loud; 20 dB = four times as loud... but even those comparisons are difficult to "hear" in a real world setting.

    The figures of merit in terms of amplifiers, I would say, are these (which we've all talked around in previous posts).

    10 dB more output takes 10 times as much power (one order of magnitude)
    20 dB more output takes 100 times as much power (two orders of magnitude)

    etc.

    Just think of the decibel as what it is, a tenth of an exponential quantity of 'intensity' called the Bel :) Drop the zero and it's like high school math.

    10^1 = 10 (10 dB)
    10^2 = 100 (20 dB)
    10^3 = 1000 (30 dB)

    1/10 = -10 dB
    1/100 = -20 dB
    1/1000 = -30 dB

    etc.

    Seems like I have heard this somewhere before...........

    Which is about right, since 74% of all statistics are made up on the spot.

    I'm clueless about most of what's written here but about 10 years ago I was at Sony's Hammerhead Studio in Charlotte listen to a video soundtrack and got a lesson in volume. The recording was mostly cars at track level and not much music coming out of 4 little JBL Speakers and they were so loud it was like being at a hard rock concert. I asked the engineer how were the little speakers not blown from the volume. He showed me a meter and said this is only 7 watts. That was a lesson.

    Hammerhead has a studio in Mooresville.

    It might be the same studio. It was by the north I-77, I-277 interchange which Charlotte was turning in to an entertainment district. A lot of businesses were relocating because of it. They even renamed the road in to the district, NC Music Factory Blvd. It was the only road in and out.

    Moorseville is a nice area except on race day.

    Yup. Horrible traffic. The NC music factory has some nice venues.

    Hammerhead was directly across the street from the Music Factory at the time. When I was there the first dinner-dance club had just opened.
