Sažetak
The Adrienne method is a measurement technique developed for in-situ measurements of sound reflection, diffraction and airborne sound insulation. Two measuring systems for determining the absorption coefficient were designed based on this method. The goal of this paper is to compare the Adrienne method of in-situ measurement of the absorption coefficient with another method which uses multiplication of the impulse responses with the ratio between estimated time of arrival of the direct and reflected incoming sound impulse, as used in some commercial acoustic measurement applications such as Easera. Speaker equalization was used in order to shrink the impulse response in time and to improve the accuracy of the measurement systems.
