Acoustics | Calculate | Intensity

Creates a new Data Block of Acoustic Intensity measurements from time waveforms or a Cross spectrum calculated from data acquired with a two-microphone Acoustic Probe

When this command is executed, a dialog box is opened.

Time Waveforms

If Time Responses is chosen as the Data Source, all of the currently open Data Blocks with time waveforms in them are listed in the dialog box.

Cross Spectra

If Cross Spectra is chosen as the Data Source, all of the open Data Blocks with Cross Spectrua in them are listed in the dialog box.

where:

Air density is calculated from the air pressure and temperature values.

SPL & P-I Index

Both SPL and P-I Index measurements can also be calculated at the same time as Acoustic Intensity by checking these selections in the Calculate Intensity dialog box.
