The laboratory is equipped with unique instrumentation, which will provide and provide knowledge, technical and software support in the process of evaluating and objectifying environmental factors in order to improve the quality of the environment and working conditions in technological operations of engineering production and to assess the environmental impact of these plants. In the laboratory, objectification of physical factors is carried out mainly noise, vibration, electromagnetic field, and solid aerosols. Within the laboratory there is an accredited laboratory SNAS - Section of objectification of environmental factors (Certificate of Accreditation No. S-292).
Focus of the laboratory
the laboratory of the environment in accordance with the requirements of the Slovak National Accreditation Service. Laboratory equipment makes it possible to improve theoretical knowledge by carrying out practical activities in the laboratory when working with modern measuring and analytical instruments. The laboratory also serves for the implementation of scientific and research activities, processing of student final works as well as for teaching the main subjects of the study programme Environmental Engineering such as: Objectification of environmental factors, acoustics and vibrations, Measurement and monitoring of environmental factors, Assessment of health impacts, Basics of psychoacoustics. In addition to these activities, the laboratory performs the following activities:
• processing the results of noise and vibration measurements in the environment and working environment,
• formation of noise studies,
• vibro-acoustic analyses and measurements of noise and vibration sources,
• visualization of noise sources of engineering products,
• localization and identification of noise sources by visualization methods,
• determination of acoustic properties of materials,
• psychoacoustic studies of sound quality of engineering products,
• optimization of sounds of engineering products,
• analysis of electromagnetic fields,
• measurement of exposure of solid aerosols in working environments.
Laboratory objectives
• Carrying out research in the field of acoustic properties of materials.
• Research and development of acoustic design of engineering products.
• Design and research into emission reductions (noise, vibration, radiation) of engineering products.
• Design and research of shading materials of electromagnetic fields.
• Carrying out psychoacoustic studies of sound quality of engineering products.
• Enable students to master work with modern measuring technology.
