Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
- Lectures provide the explanation of basic principles, subject methodology, examples of problems and their solutions.
- Laboratory exercises support practical acquiring of themes presented at lectures. Active participation of students is needed.
Participation at lectures is recommended. Participation at other ways of instruction is checked.

Evaluation of study results follows Rules for Studies and Examinations of BUT and Dean's Regulation to the Rules for Studies and Examinations of BUT. Up to 15 points is given in middle of the semester for test from theoretical knowledge related to the laboratory exercises. Up to 15 points is given for correct results and elaboration of all laboratory exercises and possible completive questions. The minimal scale of elaboration of particular laboratory exercises and completive questions are specified by a regulation issued by the guarantee of the course and updated for every academic year. Up to 70 points is given for the final written examination.

The aim of the course is to make students familiar with the chain of acoustic signal processing from their origination through their transformation to the electric signal and back to acoustic signal up to the listener's final perception.

It is mandatory to pass all laboratory exercises in regular or alternative terms to complete the course. Other forms of the checked instructions are specified by a regulation issued by the guarantee of the course and updated for every academic year.
