FOAM 02: Impedance tube measurements of two porous materials with diameter variation

This dataset consists of two csv files: 

alphas.csv: absorption coefficients vs. frequencies (comma-separated), 864 rows according to 864 measurements 

targets.csv: one-hot encoded, i.e., binary, vectors of the parameter combinations), 864 rows according to 864 measurements. The Read_Me.pdf gives further information on the one-hot encoded vectors. 

The frequencies range from 150 Hz to 1600 Hz with resolution of 2 Hz. Note that these limits are not strictly equal to the frequency limits of the impedance tube, see ISO 10534-2.
