And ... 1 KHz sine wave vs music @ the same dB ... the basis has to be noise, representing the frequency spectrum regarded to the sensitivity of the human ear?! Or to usual music, usual speaking? ... dB is some artificial thingy itself. A paradox, dB for audio claims to be related to the human ear. I heard about 3 dB, 6 dB and 10 dB as twice as loud. _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
