Pure tone audiometry
Maršálková, Leona ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
The presented master’s thesis deals with the acoustics, specifically with the selected characteristics of the sound. It focuses on the anatomy of the auditory system and its function. The work describes the testing approaches for an evaluation of the auditory organ function and introduces modern methods used for the hearing tests, especially pure tone audiometry. A part of the thesis is dedicated to a concept of an audiometer for pure tone audiometry, which is presented in a detailed block diagram along with a description of its working components. Included chapters describe the partial circuits of the audiometer supplemented by the calcuations of its individual elements. The concluding part of the thesis deals with the evaluation of the device’s functionality.

Parametrizable Music Instrument for Mobile Platforms
Řezáč, Martin ; Mlích, Jozef (referee) ; Černocký, Jan (advisor)
The goal of this thesis is to create an application, which will be primarily used as three-axis parametrizable musical instrument, respectively a modifi ed MIDI controller, suitable for Android devices. Firstly, several products, which are available on the market, are reviewed and the reader is introduced to the problematics of audio synthesis, available technologies and typical Android device potential. The next chapter is dedicated to application design. Few designs are mentioned with focus on the chosen design concept. A part of this chapter is also a speci cation of the original concept, its implementation and advantages/disadvantages. The next part is dedicated to implementation and optiomalization of some of the critical points. Also the tests are evaluated including a survey about application usability. At the end, the whole work is concluded and the further development is outlined.

Design and implementation of an automatic guitar tuner
Zatloukal, Tomáš ; Formánek, Martin (referee) ; Appel, Martin (advisor)
Goals of this thesis are design and realization of automatic guitar tuner. First, a research was carried on of availalbe tuners and sensors on the market, which is followed up by design of the hardware and software. The device processes sound emitted by string and turns guitar’s machine head via electromotor, achieving tunning. The design of the tuner is aimed to be held in one hand. Processing of entry data and control of the motor is done by development board with ESP32.

Intonation of cleft and pseudo-cleft sentences in the speech of advanced Czech learners of English
Hynková, Tereza ; Červinková Poesová, Kristýna (advisor) ; Malá, Markéta (referee)
The bachelor thesis examines the intonation of English cleft and pseudo-cleft sentences in the speech of advanced Czech ESL students. The aim of the thesis is to describe the tone choice in speech realisations of cleft and pseudo-cleft constructions produced by Czech ESL students. The first part scrutinizes literature and sets a theoretical framework for the small-scale research conducted in the second part of the thesis. The theoretical part describes the syntax of cleft and pseudo-cleft constructions, it focuses on the functional sentence perspective and provides basic information about intonation. In the second part, audio recordings are analysed in order to examine the Czech speakers' usage of tones when reading a meaningful conversation containing the target structures. It concludes that the falling tone is prevalent in the realisations of cleft sentences, whereas the productions of pseudo-clefts are more diverse. Moreover, the respondents are likely to realise three or more out of five cleft sentences using the same realisation type. They are likely to realize three or fewer out of five pseudo-cleft sentences using the same realisation type. The thesis sheds light on a marginal topic that is not popular among researchers. It compiles information on the intonation of clefts and pseudo-clefts...

Intonation of Czech Speakers When Speaking English
Houšť, Vítězslav ; Baumgartnerová, Alena (referee) ; Walek, Agata (advisor)
Intonace je často popisována jakožto pohyb výšek v mluvené řeči, který člověku pomáhá se slovním vyjádřením svých myšlenek. Tato bakalářská práce se zabývá možnými obtížemi s intonací, se kterými se může Čech setkat při mluvení anglicky, neboť mohou vést ke změně významu ním vyřčených slov. Cílem práce je se tyto potíže pokusit rozlišit, a to vysvětlením základních pojmů spojených s intonací, a jejich aplikací při porovnání nahrávek hlasů desíti Čechů vyslovujících osm anglických frází s nahrávkami stejných frází namluvenými čtyřmi rodilými mluvčími.

Radical Experience and Thinking of Poetic Inspiration. The Body (without Organs) in Maurice Blanchot's Space of Literature.
Poch, Martin ; Ševčík, Miloš (advisor) ; Jarošová, Helena (referee)
Radical Thinking and Experience of Poetic Inspiration → Abstract Blanchot's radical thinking of writer's experience poses, but do not answer a question of its physical dimension. According to Blanchot, it seems as if the writer's experience was completely unbodied, so that it excludes the possibility of writing and realization of essential speech in the world. Our interpretation of Blanchot's key concepts proceeds with an attempt to solve this problem and present its main consequences. In the last section we operate some of the terms of Deleuze and Guattari - namely becoming, the body without organs - in order to conceive writer's experience as inherently differentiated process in which the body is absent, because - deprived of its organs - it becomes an imperceptible part of assemblage which enters the space of literature.

Analysis of pitch perception depending on the spectrum
Slávik, Martin ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
This thesis is dealing with the research of the influence of individual harmonic components on the perception of sound height. As a part of the work has been made an internet questionnaire on a web address www.analyzavyšek.9e.cz, where individual respondents completed listening test compound of 46 samples. This experiment is based on semantic differential method. Individual samples are compound of sine wave – tone and examined sample, which respondents evaluates on three bipolar scales. The samples were either modelled by additive synthesis or modified sampled sounds of instruments. Individual samples were divided to four major groups and other minor groups for clarity. The purpose was to find which parts, combinations and harmonic components of sound and tone can affect perception of tone height.
