The objective is to provide suitable reverberation times for (a) clear communication for speech between teacher and student, and between students, in teaching and study spaces and (b) music teaching and performance This table contains the required mid-frequency reverberation times for rooms which are finished but unoccupied andbunfurnished. The reverberation time is quoted interms of mid-frequency reverberation time Tmf, the arithmetic average of the reverberation times in the 500Hz, 1 kHz and 2 kHz octave bands abCOR Acoustic Panels absorb 100% of these mid-frequencies. Making them a very cost effective solution to treating these rooms
