The iPhone's built in microphone is sensitive from 0 to approximately 130 decibels.

Why aren't you getting a 0 decibel reading in a quiet room? A decibel is an actual measurement of sound pressure and aside from a vacuum chamber or out in space 0 dB is not really possible to read. An average quiet room will be in the 40-50 dB range.
