That always worked for my grands as well. My youngest grandson just said the other day, "I want my dad to get one of those things that you put the thing on and it goes around and you can hear music" A four year old's description of my turntable. :love7:

Is that “C” the weighting? “A” weighting is industry standard if that’s what that is.

Probably not much different and both are loud.
some studying i did manage..

The most common weighting that is used in noise measurement is A-Weighting. Like the human ear, this effectively cuts off the lower and higher frequencies that the average person cannot hear.
Although the A-Weighted response is used for most applications, C-Weighting is also available on many sound level meters. C Weighting is usually used for Peak measurements and also in some entertainment noise measurement, where the transmission of bass noise can be a problem.

since i was putting the pedal close to the metal.. i opted for c weighted...

still learning..
