Course Description:
The study of this subject of the first part can be divided into two main parts:
1. noise, noise pollution and effect on human, physical describing of sound waves, sound levels (SWL, SPL, SIL) loudness and frequency (Fletcher-Munson curves), noise reduction methods, noise filters, noise measurement and calculation, noise map. Noise protection at the source, transmission path and receiver.
2. vibration, vibration pollution, modelling of vibration (free and damped), levels in decibels (acceleration, velocity, displacement), forced oscillations, resonance frequency (Tacoma Narrows Bridge), effects of vibration on human depend on many factors, whole body and hand-arm vibrations, vibration absorption, vibration measurement. Vibration insulation and damping.
The aim of the second part of the course is to prepare students to protect air quality by learning about the structure of the atmosphere, the damaging effects of the atmosphere, the effects of solar radiation, the greenhouse effect, the spread of pollutants, self-pollution, air quality protection limits, and emission-emission standards. In the context of the practical training, they will learn the basic concepts of dust technology, air quality measurement methods, the principles of operation of dust collection chambers, filters, cyclones and electrostatic precipitators.

Competences:
Knowledge of general and specific mathematical, natural and social scientific principles, rules, relations, and procedures as required to pursue activities in the special field of environment protection. In possession of state-of-the-art IT skills, being able to use professional databases and certain design, modelling, and simulation software depending on their specialty. Comprehensive knowledge of the basic features and interrelations of environmental elements and systems, as well as of the environmentally harmful substances affecting them. Able to perform basic tests of the quantity and quality characteristics of environmental elements and systems by state-of-the-art measuring instruments; to draw up and implement measurement plans; and to evaluate data. Able to carry out assignments as environmental officer. Able to carry out management duties subject to sufficient professional experience. Constantly upgrading their knowledge of environment protection by attending organized professional development training courses. Able to solve tasks of water, soil, air, radiation, and noise protection, as well as of waste treatment and processing at proposal level; to participate in preparing decisions; to perform authority audits; and to take part in the operation of these technologies. Able to communicate both verbally and in writing in their mother tongue and in at least one foreign language, in respect of professional issues, and to continuously develop their professional skills as required. Open to professional cooperation with specialists related to their profession but involved in other areas. Efforts to improve knowledge by on-going self-education and continuously update their knowledge of the world. Responsible proclamation and representation of the value system of the engineering profession; openness to professionally well-founded critical remarks
