So turning up the power twice is only 3 dB of power regardless !! of the power level. yet 1dB is barely noticeable in our hearing range of 100dB +/-? | |

Means, at a distance say 10 m away from the loudspeaker, increasing the power from 1000 to 2000 W will just have a minor 3 dB increase in loudness effect, although the power has been doubled. Is my understanding correct? | |
