The Effect of Reverberation Time and Signal-to-Noise Ratio On Word Recognition Scores By Adults and Children in Classrooms
This paper seeks to assess the effect of reverberation time, distribution of reverberation time over the frequency range and signal-to-noise ratio on speech intellibility by adults and children in classrooms by the use of phonetically balanced monosyllabic Turkish word recognition tests. Two sets of 25-items phonetically balanced monosyllabic Turkish words were recorded in a full anechoic chamber. Auralizations of the recordings were developed in an acoustic simulation software for a range of ...

Room Acoustic Modelling of a Reverberation Chamber
Authors:Şaher, Konca; Nas, Sezin; Karaböce, Baki; Kırbaş, Cafer; Bilgiç, Eyüp
Publisher and Date:(German Acoustical Society (DEGA), 2016)This paper aims at comparing measured broadband reverberation time values in the reverberation chamber of Scientific and Technological Research Council of Turkey - National Metrology Institute (TUBITAK-UME) in Gebze Turkey with the simulated reverberation time values from the room acoustical modelling of the same reverberation chamber. The reverberation chamber in TUBITAK-UME has a volume of 263m3 total inner surface area of 262 m2 and 16 diffusers made of Plexiglas and hung randomly in the room. ...
