In 1 meter distance human voice gives a sound pressure level of about 60 dBSPL.
0 dB is 20 µPa.
Never forget to tell the distance of the measuring microphone from the sound source, because the closer you are the louder it is.
The sound pressure level decreases by 6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.
The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
