Course Description

The course presents the broad field of acoustics and electro-acoustics. Basical acoustics. Sound. Acoustic signals. The theory and characteristics of sound field. Sound waves in closed spaces. Music and speech. Phenomena related to sound propagation. Electroacoustical-mechanical analogies. Sound sources (spherical, dipole). Resonators, absorbers, filters. Hearing acoustics. Psychoacoustics. Architectural and building acoustics. Absorption materials and constructions. Noise and vibrations. Electroacoustic transducers: microphones, loudspeakers, headphones, hydrophones and pick ups, loudspeaker box. Sound reinforcement. Ultrasound and its applications in medicine and technology. Hydroacoustics. Acoustical and electroacoustical measurements.

General Competencies

The subject gives the necessary qualifications for understanding of basic electroacoustic and acoustic principles. Based on the knowledge they have gained, the students will be able to individually solve problems from fields of acoustics, electroacoustics and audiotechnics. Understanding the properties of human hearing. Introduce the electro-acoustic transducers and their properties. The students will acquire knowledge about the widespread use of ultrasound.
