Sound level meters

    I've noticed that a lot of sound level meters on the market work within a frequency range of 100 - 8000 hz.

    What's the principle behind this? Even some of the more expensive ones only seem to offer this narrow range.

    Human hearing is not linear at varying volumes. At lower levels it's less sensitive to the high and low end of the spectrum, so most meters have an "A weighted" setting that reflects that response curve. There's another setting on most, "C weighted", which has response to higher and lower frequencies and reflects how we hear at higher volumes. What you're using the meter for determines what weighting you use.

    But for measuring what exactly is going on is a studio, or measuring how loud a guitar amp is up close, you need a meter that works across all across the spectrum, yes?

    That's perfectly adequate for a guitar amp. For the studio, get an RTA...

    Are you talking about an SPL meter/real time analyzer (RTA), or vU meters for your outboard gear?

    Can you provide a link to what you are specifically referring to?

    Or rather an RTW...

    Why do you need to know the specific SPL of a guitar amp?
