AbstractTwo computer programs were used to compare the computer simulations of acoustical conditions in classrooms. Odeon 2.6 and Raynoise 2.1 A use hybrid models in that they combine different procedures for calculating the earlier and later parts of the impulse response. The classroom had dimensions of 7.6 m×10 m and 3.3 m height. Four different sound absorption material configurations, using mineral wool, were simulated to study the relation between reverberation and speech intelligibility. The simulations showed that the speech intelligibility metrics have been consistently estimated using two different room acoustic programs. The prediction of reverberation time deviate from expected values at high frequencies for a very reverberant room.
