Lecturer:

Tutor:

Supervisor:

Department of Radioelectronics

Synopsis:

Technical Acoustics deals with description of acoustic fields in gaseous, liquid and solid media, acoustic transmitters and receivers, transducers, waveguides and presents the introduction to room acoustics, technical audiology, electroacoustical measurements, engineering acoustics and noise and vibration. The subject brings the students the survey of knowledge in acoustics.
