Spectral analysis of sound in spatial acoustics
Křenek, Jakub ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is focused on the basics concepts of room acoustics and used sound level meters. The first part focuses on the spatial acoustics and acoustic quantities used in it. Next part of thesis describe the structure and features of sound level meters. Following chapters are concerned on the PULSE system architecture and data analysis. PULSE platform contributes multi-spectral analyzer type 3560B PULSE, programming environment LabShop and microphones for difuse and free fields. The practical part describes the installation, setup and the measurement of reverberation time in the Labshop environment.

Spectral analyse of sound in space acoustics
Port, Martin ; Bereznanin, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is an introduction to the problems of acoustics and is focused on the variables describing the noise. The methodology for measuring noise in relation with valid hygiene standards is analyzed in next section. The noise levels at work required by government regulation no. 148/2006 are summarized in a subsequent charter. The next section is an introduction to the analyzer PULSE 3560B from Brüel & Kjar. This work describes a software called Labshop, which is designed to analyze noise and vibrations. It also describes the most common features Acoustilyzer NTI AL1. The practical part was to measure the reverberation, noise, frequency spectrum and plott the distribution of noise with noise maps of various auditoriums.
