Identification of the Dynamic Characteristics of a Listening Room

Dynamic characteristics of a room play a significant role in its acoustic performance. Among other dynamic parameters, the resonance frequency and modal damping are two most important factors in a room’s acoustic behavior and the efficiency of the active/passive absorbers used to control that behavior. In this paper, the experimental modal analysis (EMA) techniques will be exploited for the purpose of identification of the resonance and modal damping of a listening room, using different excitation sources and various room configurations and the accuracy of the results will be examined.
