Prediction of Random Incidence Sound Absorption Coefficients of Sound-absorbing Materials

Measuring the sound absorption coefficient (SAC) of sound-absorbing materials in a reverberation room can be expensive and predicting random incidence SACs is a complex and challenging task. This thesis begins by discussing various theoretical models for calculating the acoustic impedance and SAC of porous materials.
