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.

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.

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.

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.
