The sound stimulation consisted of short pulses of pink noise, similar to white noise but deeper, during the slow waves. Pink noise can be obtained from white noise by means of a low-pass filter designed so the output spectral power density (that is, the sound power contained within a narrow frequency band of a certain fixed width, such as 1 Hz) drops by 50 percent with each octave as the absolute frequency rises. quency response characteristics using %-octave band pink noise as the slgnal source Nominal Impedance shall be 8 ohms and power capactty shall be at least 20 watts when driven by pink noise, band-limited from 6 kHz to 20 kHz. I then take the frequency data and add the values in each 1/3 octave together. Sound masking is different than white noise because it is band limited to only overlap with the frequencies of human speech.
