Psychoacoustical Measurement of Binaural Hearing Characteristics
Novotný, Ota ; Trzos, Michal (referee) ; Schimmel, Jiří (advisor)
This diploma thesis deals with a binaural hearing issues (it means hearing by both of ears), a human hearing ability to locate position of a sound source at three-dimensional space and parameters that affect this ability. In the second part, it focuses on psychoacoustic experiment, its main features and errors that can occur and which affect a results credibility. Method of pair comparisons is described more closely here. The last part of this thesis describes a technical solution of experiment in Java environment. The application should have a graphical interface and should be able to register a new user and perform a psychoacoustical experiment. The process of experiment is following. The aplication selects a random position of defined virtual sound source on the defined range and it plays this sound into headphones on button click. The users task is to set the application controls, representing a virtual sound source position, that way, where the user hear the sound come from. On another button click the application plays the same sound, but this sound comes from application controls set position (set by user). User compares this pair of sounds and modifies the position of second sound source until these two positions are same. The application stores these results for later processing on another button click. Principles of generating testing sound sources (sine wave, narrowband noise and sound file with wav extension) and their 3D positioning by measured head model impulse responses correlation are described thereinafter. An ability of human hearing system to locate a virtual sound source in dependence on sound parameters is discussed in conclusion.

Hearing in the civil proceedings in the Czech republic an the USA
Kocumová, Zora ; Holčapek, Tomáš (advisor) ; Dvořák, Bohumil (referee)
Hearing in the civil proceedings in the Czech Republic and the USA This thesis focuses on the regulation of litigation in civil procedural law in the Czech Republic and the United States of America, describing the two and comparing them based on the gained knowledge about them. The first chapter is devoted to the general regulation of civil procedural law in both countries so that the terminology explained can be followed up with an interpretation. The similarities in the regulation of the basics of procedural law are mentioned, as well as the differences concerning, in particular, the existence of a two-track court system in the United States and the composition of the court, where the decision-making element of the jury, which is encountered in the legislation in the United States, plays a large role. The second chapter is devoted to the hearing of the case itself, either without or with an oral hearing. Greater attention is then given to the conduct of the hearing itself in both arrangements, including its preparation, opening, evidence, concentration and briefing, adjournment, and, last but not least, the announcement of the decision. The third chapter focuses on the comparison of the Czech and American regulations and the possibilities of their mutual improvement. The third chapter then...

The attitude of today's world to hearing impaired people
GRABMÜLLEROVÁ, Markéta
The main purpose of this work is to show the mindset about hearing impaired people mainly in the Czech republic in 21. century. To show the difference between accepting hearing impaired people through the history and in todays society. This work includes the differences between states like Germany, Norway and United Kingdom and czech society. Also I am writing about the possibilities that our society has created to help hearing impaired people hear again or improve their hearing and how it is making it easier for hearing impaired people to be part of our society. My work is divided to two sections. The teoretical part, where I discribed the history. I discribed some of the medical and technological divices which is made for hearing impaired people. Then I also mentioned in my theses the problems with integration and inclusion. And of course I am looking for support in our laws and their realizations. In the second part, the practical one, I focused on the proves. Those I am looking for through my interview with hearing impaired person and people from hearing society.

Use of animal models in the study of the mechanisms of subjective tinnitus.
Dittrichová, Jana ; Tureček, Rostislav (advisor) ; Kašík, Petr (referee)
Tinnitus, phantom hearing sensation, is one of the major audiological disorders affecting a significant proportion of the human population. However, the mechanisms underlying this condition remain unclear. Animal models represent an important tool in the investigation of the pathogenesis of hearing diseases. The present bachelor thesis reviews the most important findings on the possibilities of detecting tinnitus in laboratory animals, especially rats and mice, its neural correlates in the mammalian auditory system, as well as the risk factors that lead to its development and maintenance. It was found that the most common causes of tinnitus are sensorineural hearing loss induced by exposure of animals to excessive noise or ototoxic agents, as well as their genetic predisposition. These factors cause maladaptive changes in the central auditory pathway that are likely responsible for the chronic course of the disease. The changes found include, in particular, hyperactivity of neurons of the auditory nuclei of the brainstem and increased synchrony in the area of the primary auditory cortex. Using animal models, it was also found that a significant proportion of the observed pathophysiological changes result from attenuated GABAergic inhibition in the auditory pathway. This suggested a direction for...

Absolute Pitch: Theoretical Concept and Practical Issues
Bártová, Jitka ; Váňová, Hana (advisor) ; Pecháček, Stanislav (referee)
The thesis aims at complex assessment of absolute pitch both theoretically and practically. It describes the functioning of ear and main issues related to processing of sound and tone height. In addition, it clarifies related terms stemming from musical psychology. Especially, it endeavours to identify causes of absolute pitch and factors which form it. The thesis surveys several phenomena connected with absolute pitch, for example with synesthesia, and with other aspects such as occurrence of absolute pitch among population. It uses not only the Czech but especially English written literature which has not yet been used in such a scope in the Czech musical research.

Dejmková, Štěpánka ; Kotvová, Miroslava (advisor) ; Durdilová, Lucie (referee)
TITLE: Development of language skills of CODA AUTHOR: Štěpánka Dejmková DEPARTMENT: Department of Special Education SUPERVISOR: Mgr. Miroslava Kotvová ABSTRACT: Bachelor thesis with the title the Development of the language skills of CODA is focused on the description of the development and acquisition of language hearing children of deaf parents, both spoken language and sign.
