The objective of the paper is to present preliminary experimental characteristics of the new anechoic room especially built to investigate turbomachinery aeroacoustic noise. The design parameters of the facility were planned in cooperation with the Centre d'Acoustique of the Ecole Centrale de Lyon (France). The acoustic field inside the empty room was measured and its characteristics were compared with the ISO standards. All the experimental investigations have been carried out at the Institute of Turbomachinery of the Technical University of Lodz, Poland.
