Development of advanced masonnry blocks for acoustic masonry construction
Lidmilová, Klára ; Horský, Antonín (referee) ; Zach, Jiří (advisor)
This thesis deals with study of sound behaviour in the field of partition structures, especially inter-residential partitions, evaluation of structures in terms of acoustic insulation properties and the production of ceramics in general and acoustic masonry elements. Based on a literature search and market research, new ways of solving acoustic-insulating masonry, including construction, were proposed. The feasibility of construction was verified on a small-scale model created using 3D printing. The selected masonry element was further developed into various dimensional modules, which were compared on the basis of the weights of the individual elements and on the basis of the number of joints. Furthermore, the levels of lightening of the elements were adjusted in order to achieve the highest possible values of the basis weight of the masonry and thus the highest possible airborne sound insulation.

The Effect of Raw Materials on Sound Insulation of Brick Body
Bosák, Filip ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
Diploma thesis is concerned with opportunities of increase sound isolution index for bricks. In theoretical part is summary of present knowledge about acoustic properties ceramic body field and theoretical calculations and measuring sound insulation as well as. Practically part is divided on apply and basic research. Under apply research is experiment, that considers impact quantity of raw materials using at brick factory in the Holice on the most significant technological properties of plastic paste and brick body, additionaly with the considering chances of increase sound insulation index. In basic research is experiment, that evaluates impact common use domestic brick´s raw materials on sound insulation. Sound insulation is evaluated indirectly by transsmision rate of ultrasound in a both cases.

Determination of acoustic properties of brick body
Hladík, Lukáš ; Skotal, Zbyněk (referee) ; Sokolář, Radomír (advisor)
Bachelor thesis deals with the possibility of increasing the index of the air soundless the wall brick forms. The theoretical part summarizes the present knowledge in the field of acoustic properties of the ceramic shard and also the theory and methodology of the appraisal the index of the air soundless of building materials. Then there is the possibility of using ultrasound for indirect appraisal of the index the air soundless of a brick shard described both in the theoretical part in the form of a research of existing sources and in the practical part.

History and acoustics of traditional timber joist floor structures
Kalousek, Lubor ; Fišarová, Zuzana
The article is focused on the issue of traditional timber joist floor structures, especially from the end of the 19th century to the first half of the 20th century. In common building practice, we very often encounter these structures in residential buildings that are, or were in the past, the subject of structural changes. Unfortunately, during these interventions, the basic ideas of the original technical solution are not always respected and some physical parameters of building are degraded, of which the requirements of building acoustics will be discussed in particular. However, the problem includes not only the actual composition of timber joist floor structure, but also the floor, which forms an integral whole in interaction with it. The article will describe the principles that were devoted to these types of structures in historical legislative and standard regulations and further in professional literature. The original historical solution will be presented on a practical example. In relation to building interventions in historic timber joist floor structures, current legislative and standard regulations will be described, as well as examples of modern solutions and their limitations.
