I guess this was an old radio ratio for music and speaker and yes, it was interpreted as "twice as", also 6 dB, but if you mix music it can be 9 dB or 12 dB since you get this impression. So I guess 10 dB is most common. For math it might be 6 dB, regarding to twice as far to the sound source, what not really must result in half as loud. _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
