Determination of the Reverberation Time Using the Measurement of Sound Decay Curves
Applied Sciences, 2023 In the measurements of reverberation time, measurement methods of different accuracy are used depending on the room. For ordinary rooms, the measurements are made using the interrupted noise method, which consists of determining the decay curve after ...

Recall of Reverberant Speech in Quiet and Four-Talker Babble Noise
Brain Sciences, 2021 Using behavioral evaluation of free recall performance, we investigated whether reverberation and/or noise affected memory performance in normal-hearing adults. Thirty-four participants performed a free-recall task in which they were instructed to repeat

Metasurfaced Reverberation Chamber [PDF]
Scientific Reports, 2018 AbstractThe concept of metasurfaced reverberation chamber (RC) is introduced in this paper. It is shown that by coating the chamber wall with a rotating 1-bit random coding metasurface, it is possible to enlarge the test zone of the RC while maintaining the field uniformity as good as that in a traditional RC with mechanical stirrers.
