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. The majority of the diffusers have hyperbolic shapes. There are also six absorbers to adjust the reverberation time of the room. Indications of difficulties in the calibration of the acoustic model with reference to the measured values and different frequencies are given and the modelling and measurement uncertainties and limitations are discussed. © 2016 German Acoustical Society (DEGA).
