Hello Bob, For uniform quantization, the S/N is 6n+4.77+(Smean/Speak) Smean/Speak is the mean to peak ratio for the signal. For a sine wave it is just -3 dB; however for speech it will be much higher. It will be more like -13dB. And of course music will probably be closer to the speech value than the sine wave value. Look at Rabiner & Schafer "Digital Processing of Speech Signals" for details. "Speech Processing" edited by Chris Rowden covers this as well.
