In acoustics, sound pressure or acoustic pressure is the pressure difference between the ambient (average or equilibrium) atmospheric pressure and that of a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal (Pa).
The analysis highlights Measurement, Sound pressure level and Sound measurements as prominent areas in the source structure around Sound pressure.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
