Acoustics and Ultrasound

Principles of physical acoustics, human ear and perception of sound. Human speech. Room acoustics, sound reinforcement systems, anechoic chamber. Sound isolation and sound damping. Protection against noise. Microphone as acoustic-to-electric transducer. Speech and music recording. Speaker as electric-to-acoustic transducer. Modelling and simulation of acoustic systems. Ultrasonic transducers. Digital processing of acoustic signals. Blind source separation, convolution mixing, cocktail-party problem. Multimedia systems, sound effects, spatial sound, audio recording compression, MIDI protocol, algorithms and standards, AES3 standard. Evaluation of digital systems. Devices for sound recording and reproduction, noise and dynamic reduction systems. Noise and vibrations. Physical characteristics of noise and vibrations. Noise and vibrations influence on people's health. Infrasound. Noise and vibration measurement.

Students learn about the basics of acoustics, electroacoustic, measurement of audio system parameters, noise measurement, ultrasound vibrations and acoustic signal processing.

Students create an individual seminar in the form of an article and present it with an appearance in front of the auditorium. They learn to search independently and to select resources (books, magazines, articles, internet) and write an article in accordance with the requirements for publication in an expert magazine.

Lectures, demonstrations, preparation and presentation of individual seminar or project.
