Subject description


  • Enrollment in the study year.

Content (Syllabus outline):

Sound waves (vibrations, wave equation, impedance, reflection, refraction, sound sources). Psychoacoustics (human auditory system, sound loudness, frequency and temporal masking, critical bands). Localization of sound (perception of azimuth, elevation, distance; head transfer functions, ITD, ILD). Spatial acoustics (absorption and reverberance, positions of speakers and listeners, the impact of different rooms). Electroacoustics and transduction (speakers, microphones, various sensors). Underwater acoustics (sound waves in water, the speed of sound, reflections, underwater communication, sonar). Acoustics in human-machine interaction (acoustic menus, warning systems, navigation).

Objectives and competences:

Understanding basics of acoustics and sound as an important element in the communication between human beings and in the human-machine interaction. The emphasis is on learning about the basic physical characteristics of sound waves in different media and rooms and the ability of human comprehension and localization of sound. Understanding the basic principles of speakers and microphones as the fundamental building blocks of most telecommunication systems. Presentation of the so-called underwater acoustics, the operation of sonar and other sensors.

Intended learning outcomes:

Basic knowledge of sound waves, the operation of acoustic devices and the ability of perception of sound by humans in different environments.

Learning and teaching methods:

Lectures in which the student is acquainted with the theoretical basics and lab work where the student meets the practical problems and solves them in the team.
