Changes in the acoustics of the Moscow Conservatory Great Hall two years after reconstruction

We present the results of measuring the reverberation time of the Moscow Conservatory Great Hall. Measurements were conducted with a half-year interval over two years after completion of reconstruction. It is demonstrated that the changes in reverberation time at low and middle frequencies are barely distinguishable to subjective perception, and at high frequencies, significant fluctuations are observed, related to seasonal changes in the climatic conditons.
