No. 10dB is the volume of calm breathing, 0dB is the threshold for auditory perception of a sound at 1kHz.
With regards to a CD, the decibel measures the gain rather than the volume. 0dB in this context simply means "full volume", while -10dB means 10% of full volume, and -20dB means 1% of full volume.
