Introducing students to the phenomena of noise and vibration from the engineering point of view, with the aim of creating mathematical foundation, determining the cause of generation, and the reflections to the working environment as well as ther identification, measurement and repair.

Creating a deep insight into the phenomena related to noise and vibration in working environment, training students to recognise and detect them as well as to remove or control unwanted consequences on health and professional exposions.

The concept of sound and noise. Sound intensity and sound pressure. Acceptable sound pressure level from the noise. Sound power levels of noise sources and characteristics. Physiological acoustics. Acoustics of enclosed space. Absorption characteristics. Reverberation time. The size, shape and design of the rooms as the acoustic parameters. Noise isolation. Occupational noise pollution regulations. Identification of noise sources. Calculation of the sound field of industrial plants. Criteria for evaluating security solution. Design methods of protection. Transmissibility. Vibration isolation. Active methods of protection. Passive methods of protection. Equipment for protection against noise and vibration.

Lectures. Auditory exercises. Laboratory exercises. Consultation. Continuous monitoring of the level of students knowledge through four tests (mandatory) and laboratory exercises. Examination.
