The Automation of Sound Absorption Coefficient Measurement
, 2009 By manual method, the sound absorption coefficient measurement should be done by utilizing many type of equipment such as: measuring amplifier, level recorder, band-pass filter, protactor, etc. However it caused inefficient and need longer time in processing measurement data, therefore the automation system of sound absorption coefficient has been ...

Estimation of Sound absorption Coefficient from the Sound Power
International Journal of Emerging Trends in Engineering Research, 2022Sound absorption measurements were carried out in the reverberant room in accordance with ISO354. The present paper gives an experimental technique to estimate the sound absorption coefficient of a material based on the sound power in the reverberation room according to ISO 3741. This is in order to be able to calculate the sound absorption coefficient
