  The reverberation time is one of the most important parameters used to
characterize the acoustic property of an enclosure. In real-world scenarios, it
is much more convenient to estimate the reverberation time blindly from
recorded speech compared to the traditional acoustic measurement techniques
using professional measurement instruments. However, the recorded speech is
often corrupted by noise, which has a detrimental effect on the estimation
accuracy of the reverberation time. To address this issue, this paper proposes
a two-stage blind reverberation time estimation method based on noise-aware
time-frequency masking. This proposed method has a good ability to distinguish
the reverberation tails from the noise, thus improving the estimation accuracy
of reverberation time in noisy scenarios. The simulated and real-world acoustic
experimental results show that the proposed method significantly outperforms
other methods in challenging scenarios.
