ambient pressure
Science; Acoustics
The ambient pressure is the pressure of the surrounding medium. The SI unit is the Pascal - Pa which is very small relative to the atmospheric pressure.
flux density
Science; Acoustics
The amount of magnetic, electric, or other flux passing through a unit area.
peak-to-peak
Science; Acoustics
The amplitude difference between the most positive and most negative value in a time waveform, that is, the total amplitude.
order analysis
Science; Acoustics
The analysis of harmonics related to rotational speed. The application of harmonic analysis to rotating machinery.
phase shift
Science; Acoustics
The angular difference between two signals, which reflects the time difference.
post processing
Science; Acoustics
The application of a mathematical function to a signal after measurement to further improve the information that can be obtained from the analysis.
