About the department

The Department of Mechanics and Vibroacoustics AGH performs research activities in the fields of acoustics and mechanics including: technical and architectural acoustics, vibroacoustics and sound engineering, modelling of vibroacoustic hazards in the environment, vibroacoustic diagnostics and machine dynamics (with special regard to vibration isolation and vibration of machines/machine vibration).

The research in the field of vibroacoustics involves modelling, identification and analysis of vibroacoustic processes taking place in nature and technology, utilisation of active methods (control) in vibration damping and noise suppression. The research is also conducted on using a strong sound field for the purposes of cleaning power equipment, testing the properties of vibration isolators and sound absorbers, development of solutions for reducing noise and vibrations of machines and equipment, as well as development of methods and means for acoustical diagnostics.

It conducts extensive works in the field of sound engineering, especially auralisation and digital conversion of signals by means of signal processors, including methods of modifying recorded sounds to the desired listening parameters, filtration and prediction of distortions in the processes of vibration monitoring of rotating machinery.

The Department also develops methods for testing interior acoustics, conducts research on the effectiveness of acoustic treatment and methods for the assessment of interiors’ acoustic quality. It also works on new technologies of sound control.

Additionally, it also conducts numerous studies on the solutions in the field of mechanics, mainly to the issue of analysis and synthesis of mechanical systems investigated in discrete-continuous models, including those applied to the issues of vibration isolation or the needs of vibration technology. Development of IT systems, both hardware and software, led to the situation that various computer algorithms are naturally developed for technical applications, including storage, processing and distribution of data as well as numerical modelling of sound field and advanced dynamic analysis.

The other basic fields of research conducted in the Department of Mechanics and Vibroacoustics concerns application of the finite element method (FEM) and boundary element method (BEM) in mechanics and acoustics. At the same time, it carries out studies on application of these methods in analysis of sound field in the immediate area of operating machines and equipment, and also studies on application of geometrical methods in sound field modelling.

In all areas of its activity, the Department cooperates with numerous Polish and international scientific institutions. The cooperation covers short-term scientific internships aiming at the exchange of scientific experiences, cooperation in research and publications. The Department’s employees participate in scientific works of international organisations, in editorial committees and scientific committees of various symposia and conferences. The department hosts and co-hosts many national and international conferences in the field of vibroacoustics and diagnostics, for example Open Seminar on Acoustics, Active Noise and Vibration Control Methods, Wibrotech, Forum Acusticum, Euronoise, Internoise.
