Course detail

Measurements for Audio and Acoustics

FEKT-MPC-AMAAcad. year: 2024/2025

The subject is focused on measurements of audio equipment, acoustic and electroacoustic measurement according to international recommendations in these fields. Laboratory practices are focused on the realization of projects in LabView and Matlab for the automated measurement of audio equipment, electroacoustic devices and noise in various industrial measuring systems and bulk processing of measured data, especially using VBA programming language. In laboratory exercises, the Brüel & Kjaer, Audio Precision and NTi Audio measuring systems are used.

Language of instruction

Czech

Number of ECTS credits

6

Mode of study

Not applicable.

Entry knowledge

Knowledge of principles and control of instruments for measuring voltage, current and frequency, knowledge of the operation of digital generators, oscilloscopes and spectral analyzers, knowledge of principles of measurement of current, voltage, frequency, impedance and total harmonic distortion, knowledge of C language and work with spreadsheet editor are required.

Rules for evaluation and completion of the course

Evaluation of study results follow the BUT Rules for Studies and Examinations and Dean's Regulation complementing the BUT Rules for Studies and Examinations. Up to 40 points can be obtained for elaboration of all individual work and laboratory exercises and in order to be awarded a credit, it is necessary to obtain at least 1 point from each individual work and laboratory task. The minimal scope of the elaboration of a particular laboratory exercise and the complementary questions are specified by a regulation issued by the guarantor of the course and updated for every academic year. Up to 60 points are given for the final examination, and it is necessary to get at least 30 points for its successful completion.
In the case of distance learning, laboratory excercises are replaced by homework evaluated with the same number of points. The exam will take place in person, in justified cases remotely.
It is obligatory to undergo all laboratory exercises in regular or alternative terms to complete the course. Other forms of checked instruction are specified by a regulation issued by the guarantor of the course and updated for every academic year.

Aims

The aim of the course is to introduce students to modern methods and devices for measurements in acoustics, electroacoustics and audio technology.
- use the correct method for automated measurement of a given quantity,
On completion of the course, students are able to:
- create an automated measurement project for typical applications in acoustics, electroacoustics and audio engineering,
- perform bulk processing of measured data using a spreadsheet editor,
- create and edit macros in the VBA for bulk processing of measured data,
- create functions in VBA for remote control of automated measurement systems.
