Technical Acoustics Laboratory

Description

Conducting scientific and industrial research in the fields of technical acoustics, architectural and building acoustics, and electroacoustics. Detailed scope of activities includes: Measurement of the acoustic power of machines and devices using technical and laboratory methods in reverberation or anechoic chambers (ISO standards 3741, 3743, 3745). Measurement of sound directivity, speaker efficiency, amplitude-frequency characteristics, and nonlinear distortions. Measurement of interior acoustics parameters, including reverberation time and other parameters (ISO standard 3382). Measurement of Open-Space office acoustics (ISO standard 3382-3). Measurement of acoustic absorption and sound absorption coefficients in a reverberation chamber (ISO standard 354). Measurement of sound scattering (ISO standard 17497). Measurement of sound absorption using an impedance tube.
