M44071) Basic Information
Course specification
Course is active from 01.10.2005.. 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 and living environment as well as ther identification, measurement and repair. Creating a deep insight into the phenomena related to noise and vibration, training students to recognise and detect them as well as to remove or control unwanted consequences. The concept of sound and noise. Propagation of sound waves. Plane waves. Spherical waves. Sound intensity and sound pressure. Acceptable sound pressure level from the noise. Acoustic impedance. Sound power levels of noise sources and characteristics. Diffraction and reflection of sound. Noise spectrum. Acoustics of enclosed space. Absorption characteristics. Reverberation time. The size, shape and design of the rooms as the acoustic parameters. Noise isolation. transmissibility. Vibration isolation. Technical measures of protection against noise and vibration. Active methods of protection. Passive methods of protection. Identification of noise sources. Lectures with presentations and animations. Auditory exercises. Consultation. Continuous monitoring of the level of students knowledge through four tests (mandatory). Examination.
