Comments on “Empirical Prediction of Speech Levels and Reverberation in Classrooms” [Build Acoust, 8(1), 1–14, 2001]
The goal of this letter is to comments on the article “Empirical Prediction of Speech Levels and Reverberation in Classrooms” by Hodgson (2001). Hodgson proposed an empirical equation for prediction of classroom early decay time. Hodgson EDT equation with regard to the classroom ceiling height was theoretically discussed and it was concluded that when a classroom ceiling height is decreased or increased, it is not reasonable to judge about the acoustical condition of the new space based on the Hodgson EDT equation if the average absorption coefficient of the additional walls is equal to the average absorption coefficient of the original space.
