Pressure and Velocity Vector Data from Transducer and PIV Measurements of Recorder Interior under Normal Playing Conditions with Various Tone Hole Configurations

Pressure data is stored as 8 channel .wav files:Channel 1: stores mouth pressure level.Channels 2-6: store pressure along the tube in sequential order at x locations [298.1, 413.5, 522.4, 614.4, 681.0] mm.Channel 7: stores audio as recorded outside the instrument (in front of the labium).Channel 8: stores synchronisation data of laser pulses.Individual files contain pressure data for each experimental case. A single file contains measurements at each instance of PIV measurement, resulting in 7 repetitions for each PIV FoV. There is a 2-second gap between the repetition to indicate a different FoV.

Individual files contain pressure data for each experimental case. Within a single file, measurements are repeated seven times, each corresponding to a different FoV of PIV. There is a 2-second gap between the repetitions to indicate the transition from one FoV to the next.

Pressure transducers (Channels 1-6) sensitivity: [18.88, 21.121, 19.093, 18.466, 15.736, 17.647] mV/kPa.Amplifier gain was set to 80 and recording software gain was set to 2.0

Procedure to time align pressure and flow data using channel 8 is not ready, but will be updated when available.

Flow data is organised as follows:

ui*** - horizontal velocity vectorsvi*** - vertical velocity vectors

**09* - diameter indication of the tone hole in millimetres****R - this case is a tone hole with a rounded undercut****T - this case is a tall tone hole 

*F_rms_Regular holds RMS values for cases: 00, 09, 12 and 15 *F_rms_Extra holds RMS values for cases: 09R, 09T, 15R and 15T

The files xlFullAllCases.mat and ylFullAllCases.mat hold spatial x and y values for all the cases, respectively. The case name is indicated in the name of the tag, followed by a FoV index.
