Structural Chemistry of Silicates air. Pressure fluctuations associated with acoustic signals are usually very small compared to the large background pressure field. The atmospheric pressure is around . Pa, while the amplitude of the smallest recognizable acoustic disturbance for a human being is around . Pa.
