Note that the noise n[k] considered here is mostly stationary and was recorded under the same reverberation conditions as the RIR measurement [8].
For instance, even if two subjects hear exactly the same reverberant sound and are asked about their perceived amount of reverberation, their responses will probably be different.
However, for the same noise and reverberation conditions, the RMSE drops evidently as the number of microphones increases for all the algorithms, particularly in the high noise condition.
However, when comparing the SIR gains for the same SNRs across different reverberation times, there are significant differences especially at the reverberation time of RT60 = 300 ms. For example, for the case of corrupting babble noise, for RT60=0 ms the recorded SIR was 16.14 dB, whereas when RT60 = 300 ms the SIR drops to 11.28 dB.
An analysis by Leo Beranek (cofounder of BBN) in the 1960s had shown that the early sounds were special: concert halls preferred by conductors were similar in that the time between the first sound and the first reverberation was about the same.
For the sake of comparison, we conducted the same experiments with two other blind reverberation compensation strategies, namely LTLSS (method 3) and an MSLP-GSS-based method (method 4).
When the SSI steel plant 10 miles up the road in Redcar shut in October with the direct loss of 2,200 jobs and the same again in the supply chain, the reverberations were felt across Teesside.
In the DM initialization, the two main assumptions are that reverberation effects are convolutive and long term, and that the same transformations can be used to decorrelate each reverberation condition.
The altos are on F natural before the reverberation has decayed; on the same syllable, the trebles are asked to re-articulate a note, necessitating a subtle glottal stop.
One interesting and relatively recent reverberation of realignment is that the same anxiety that exists at much of the major conference level appears to be filtering down to leagues outside the Football Bowl Subdivision.
