#-18db

in the broadcast and film industry, the reference before each 'serious' program is set at -18dB, and voices should modulate in between -12 and -6 dB, and when more tracks are in play, you need to mix accordingly, adjust each so that the result (main output) peaks around -6dB and still pleases your ears Yes explosions peakin' at -1dB, but seriously that should be about it...think in reality, what is naturally loud/soft, etc. and not a fan of compression here, as it reduce the dramatic effect of audio - only used when mandatory !!!
