PSU Normal Impedance Tube Data Processing

MATLAB code to process normal impedance tube data according to ASTM standard E1050

Getting Started

Clone repository (Git Bash Download)

git clone git@github.com:ats5662/PSU_Normal_Impedance_Tube.git

or

git clone https://github.com/ats5662/PSU_Normal_Impedance_Tube.git

Change directory to the main mlx script

cd "~/PSU_Normal_Impedance_Tube/ProcessData/"

Open mlx file and set paths

dataFilesPath = "~/PSU_Normal_Impedance_Tube/ExampleData/";
processScriptPath = "~/PSU_Normal_Impedance_Tube/ProcessData/ProcessDataNIT_ASTM_E1050.mlx";
outputPath = "~/PSU_Normal_Impedance_Tube/ExampleOutputs/";
outputReportName = "ExampleOutput.pdf";
addpath("~/PSU_Normal_Impedance_Tube/Functions/")

Navigate to the live editor ribbon and hit run

2 different outputs

• PDF and HTML report with

  • OASPL vs. time plots for each test

  • Absorption coefficient vs. frequency plots for each test

  • Attenuation vs. frequency plots for each test

  • Specific impedance ratio (resistance and reactance) vs. frequency plots for each test

• CSV data export

  • Absorption, reflection, attenuation, and specific impedance ratio (resistance and reactance) as a function of frequency for each test

  • Timeseries OASPL data for each test
