Application for Testing Critical Listening Skills
Ecler, David ; Říha, Kamil (referee) ; Schimmel, Jiří (advisor)
My work is aimed at providing a comprehensive overview of hearing testing applications, and thus acquiring the sound engineer’s skill of critical listening. The thesis presents the different types of critical aspects of audio signals, then a summary of the possibilities of testing these critical signals, a description of the different tests and exercises, including the conditions of their performance. The tests are divided into chapters according to their focus. In the practical section, I have programmed some of the tests that can be used to acquire and practice critical listening skills. The tests are programmed in the Matlab App environment.

Establishment of database of musical instruments recordings
Lavický, Vojtěch ; Mácha, Tomáš (referee) ; Rášo, Ondřej (advisor)
In this Bachelor thesis you can find created database of musical instruments. Recordings are descripted by it's waveforms and sectrograms. It may serve for example for removing noise from signal. A general data of instruments are descripted here. Human earing and his perception of sound is discuss here. There are also included parameters of sound itself and theory of calculations. Frequency and dynamic range are written to every instrument in database. These are consequently range by its size. As a part of the thesis is program with graphical user interface. The program include all the recordings from database and is open to any other recordings.

Sound level meter for embedded systems
Stejskal, Tomáš ; Schimmel, Jiří (referee) ; Botta, Miroslav (advisor)
The aim of this work is the design and implementation of a sound level meter for emdedded systems. It is designed sound level meter sensor. This sensor includes a microphone, microphone preamplifier and ADC. This sensor is connected to a development kit STM32F4 Discovery, where sound is processed. It is processed filtration, time weighting, calculation of sound leve and loudness weighting. The sound level is then sent via the serial communication USART. This thesis includes a theoretical analysis of noise and its human perceptions. It also describes the development platform used.
