AB  - The correct estimation of the reverberation time of the room acoustics can be an important task for several systems such as sound localizers, hearing-aids and telephony. These systems are affected by reverberation and needs an estimate of this acoustic parameter in order to adapt the algorithms to different environments. This article presents a method to estimate the reverberation time of a room widthout using test signals. From the captured signals in the room, the system is able to estimate the reverberation time without any prior knowledge of the sound sources or room geometry. The estimates are obtained from the "tails" of the sounds, and we use a run-length energy integral followed by an algorithm that estimates the decay of the sound energy.
