Estimation of sound absorption coefficient at modal frequencies using decay time measurements and eigenvalue model in a small room

Measuring the sound Fenders (Rear) absorption coefficient in a small reverberation room below the Schroeder frequency is a challenging task and the results are subject to a high degree of uncertainty.Recent research shows that the low-frequency acoustic properties of the enclosure and the test sample should be characterized by quantities that descr
