TomTuttle and Misfit:

Indeed. Just set the level with the pink-noise generator to "fairly loud" or a comfortably loud level, usually around 80 dB SPL (C weighting) at your listening position. 85 dB SPL is termed "quite loud" and 75 dB SPL may not be quite loud enough to get accurate measurements with the Radio Shack meter. If you don't have a meter, you can do approximate adjustments by ear, but an SPL meter is considerably more accurate.
