Evaluation and modelling of Traffic Noise
Černoch, Adam ; Spies, Karel (referee) ; Kudrna, Jan (advisor)
The task of the master's thesis is introduction with the problems of traffic noise, focusing on noise from road traffic. There is a description what is the noise, how it is formed, its resources and what are the methods of measuring. The following are the various noise reduction measures such as noise barriers and low noise pavements. The main attention is devoted to the noise generated at the tire / road that is reduced by these pavements. The practical part describes the implemented measurements on individual sections at various locations in our country. The measurement was carried by slightly modified method CPX with reference tire directly at the vehicle. The main aim was to evaluate the measurement data, make comparison of different low-noise surfaces with each other and with the commonly used surfaces. Then quantification of the rate reduction of the noise emission for a given section and verification of input data for noise modeling. In conclusion, the obtained results are summarized and based on them were confirmed very good acoustic properties with the recommendation to continue with measurements in the future.

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.
