Taylor et al - Inhaler inhalation audio and flow data
datasetposted on 28.03.2018 by Terence E. Taylor, Helena Lacalle Muls, Richard W Costello, Richard B Reilly
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
The .mat file contains data in the form of a 287x4 cell matrix. Each row corresponds to a different inhaler inhalation recording. Column 1 contains the anonymized participant numbers, Column 2 contains the inspiratory flow range group to which each recording belongs to. Details of this labeling is given in the manuscript. Column 3 contains the inhalation flow signals and Column 4 contains the acoustic envelope signals from the inhalation audio recordings. Signals are low pass filtered below 4Hz. Moving average filter not applied to acoustic envelope signals until after flow estimation.
