Evaluation of Traffic Noise
Mejzlík, Martin ; Spies, Karel (referee) ; Kudrna, Jan (advisor)
This thesis deals with issue of traffic noise, its measurement and data evaluation. Theoretic part of my work concretes basic information about acoustics and also describes and analyzes traffic noise sources of tire/pavement. Next part deals with quite pavement and with measurement methods of traffic noise. Practical part of my thesis contains description, results and evaluation of realized measurement with methods CPX and SPB.

Noise Generator Diagnostics
Plucková, Iveta ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The bachelor thesis deals with noise diagnostics of the generator. The practical part of the thesis is realized in the Dukovany Nuclear Power Plant. The first part of the thesis, noise is generally discussed. The quantities and their measurements are described, quite generally, also for the given company. According to specific conditions in the Dukovany Nuclear Power Plant, there is a distribution of noise measurements, which is carried out by an external company. The work gives a concrete example of this measurement. At the end of the work, the practical measurements of noise were done for selected generators, which were realized by an author for the purposes of this bachelor thesis. The experiment is evaluated.

Evaluation of pavement surface noise reductions
Mejzlík, Martin ; Spies, Karel (referee) ; Kudrna, Jan (advisor)
The aim of the bachelor´s thesis is to make an introduction to quiet pavements, analyzing the sources of tire/pavement noise, study the principles of this pavement and summarize their properties. This thesis deals with method of measurement tire/pavement noise and evaluate the concrete measurements. The main aim of the thesis is to evaluate measurement in Zádveřice near Zlín.

Measurement of Noise During Rainwater Flow Through the Roof Drain Body
Fučík, David ; Ručka, Jan
The article deals with the issue of measuring the flow and noise that arises in the vicinity of the siphonic drainage system during the outflow of rainwater from the roof surface. Rainwater is drained from the roof level through roof drains, which are fitted into vertical penetrations in the roof structure. The article describes the basic issues of flow and noise measurement, which refers to technical standards and other literature. According to the given requirements, the parameters of several siphonic roof drains from various manufacturers will be measured. Subsequently, the measured data will be compared and evaluated.
