Autonomous tool for measuring audiogram and frequency masking
Pachel, Jakub ; Sigmund, Milan (referee) ; Malucha, Jan (advisor)
The first half of the bachelor's thesis is focused on the theory of sound, it deals with the description of human hearing, some of hearing impairments and their impact on the hearing threshold, a description of simultaneous masking, and the introduction of hearing test methods. The second half introduces an audiometer's design and block diagram for pure-tone audiometry, which was programmed in the MATLAB development platform. Furthermore, the thesis presents the measurement results of the audiometer for five subjects. Finally, it describes how the program was supplemented with a graphical user interface with the possibility of adding masking tones and noises into the measurement process.

Design of Hearing Aids in LabVIEW
Macíček, Ondřej ; Tannenberg, Milan (referee) ; Sekora, Jiří (advisor)
This thesis contains the block diagram of hearing aid, anatomy description of human hearing system and description of most important physical values in this problematics of hearing and sound. There are analyzed several types of hearing tests for diagnosis of the hearing loss level and some types of algorithms, which fit the frequency characteristic of patient's hearing loss too. Further this thesis contains interactive program of hearing aid, which has implemented equations for sound equalization.

Audiogam measurement with LabView
Placzek, Roman ; Chmelař, Milan (referee) ; Kolář, Radim (advisor)
The project deals with hearing disorders and examination of hearing and mainly with construct audiometer with the help of sound card and computer program LabView. Thesis describes requirements for audiometers and its realization in LabView with detailed description of all controls and blocks. Headphone for audiometer is also described here, including measurement of its characteristics and calibration. As a part of this project, the manual for calibration and manual for examination of hearing in the program Audiometr is included.

Audiometry
Stanický, Ondřej ; Chmelař, Milan (referee) ; Hrozek, Jan (advisor)
The first part of the thesis focuses on theory and deals with the basic physical terms as far as acoustics is concerned. It also deals with a description of auditory system, as well as graphical results of audiometrical methods. The second part to the thesis deals with a scheme of audiometer for hearing tests. It also deals with the description of the programme as well as the transfer of the decibel scale to electric voltage and its correction. The last chapter contains the data collected during the hearing tests.

Design of hearing aid
Svoboda, Adam ; Janoušek, Oto (referee) ; Kolářová, Jana (advisor)
This bachelor’s thesis deals with the physiology of the auditory system and defects that cause temporary or complete deafness. It was created program in Matlab, which allows modification of the speech signal to simulate hearing loss and subsequent multi-channel amplification, presenting function of the digital hearing aid. It also deals with distribution of hearing aids according to the material and software and there is dismantled some modern systems from Siemens and functions that may include hearing aids.

Testing of Hearing Ability in LabVIEW
Stanický, Ondřej ; Tannenberg, Milan (referee) ; Sekora, Jiří (advisor)
The thesis is concerning the studies of certain methods used for examination of hearing and description of protocoles of examination audiogram. There is also described the anatomy, properties and protection of the human hearing. Another part is dealing with properties and proposal of block diagram of audiometry, eventually the realization of audiometry in environment Labview and description of certain parts of programm.
