Acoustic generator for evoked potentials stimulation
Škutková, Helena ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
Evoked potentials are electric brain response to external stimulus. They are important diagnostic no visual method in neurology. For their excitation use of different of kinds stimulation, most often: visual, auditory, somatosenzory, olfactory and gustatory. Evoked potentials are objective method for measurement sense perception. This master’s thesis is specialized to auditory evoked potentials and design acoustic generator for their stimulation. Auditory evoked potentials are primary used for objective audiometry, but they have another usage. In the first place, application is specialized on health sector. The aim of this master’s thesis is compact specified medical requirements with available technical resources.

The construction for the innovative Jecklin Disk microphone technique
Strážnický, Martin ; Musil, Jaroslav (referee) ; Jirásek, Ondřej (advisor)
The thesis deals with the design and subsequent measurement of the parameters of the Jecklin disc pair microphone array. The theoretical part deals with human hearing, microphone characteristics and types of stereo microphone technology. The practical part focuses on the measurement of the directivity and width of the stereo image when changing the configuration of the array. The measured results are then verified in practice by recording acoustic musical instruments.
