Zero dB is the quietest sound that may be heard by the average of a group of young men who have not been noise exposed. By definition, one half of these will be able to hear a quieter sound, and the other half will be less sensitive. Nowadays, these limits are more precisely defined in terms of physical units. Some animals hear at a different sensitivity to us, and over a different frequency range.

The human auditory threshold (absolute threshold of hearing) is a sound pressure of 20 µPa (micropascals), at 1000 Hz, as determined by the RMS (root mean square) method*. It is, as close as can be determined, the quietest sound that human hearing can detect.* This is an average, so by definition, at least some of the subjects probably were able to hear slightly quieter sounds.
