What does the "-20db", "-38db" and "-44db" indicate in the three examples of popular mics listed below. I guess a good way to answer it would be by saying "the -20db is _____ compared to the -44db".

Output Level: -20 dB below 1 volt per microbar at 1 kHz into 1 megohm load

Output Level: -38 dB below 1 volt per microbar at 1 kHz into 1 megohm load

Output Level: -44 dB below 1 volt per microbar at 1 kHz into 1 megohm load

All they are telling you is the volume level the microphone delivers to the radio.

Well, that's what I kind of figured. Since it's in negative numbers it's not so easily defined. Put bluntly, which delivers more regarding the above, -44db or -20db?
