The use of neural network analysis to predict the acoustic performance of large rooms part II. Predictions of the acoustical attributes of concert halls utilizing measured data

摘要

A method of predicting the G values (The strength factor in dB), C_80 values (the clarity factor in dB) and LF (the lateral energy fraction) in concert halls has been investigated. Constructional and acoustical data for 72 unoccupied concert halls has been investigated. Constructional and acoustical data for 72 unoccupied concert halls, in various countries, were Utilized for the neural network analyses.
