Abstract:

Lightweight building materials are now commonly employed in many countries in preference to heavyweight materials. This has lead to extensive research into the sound transmission loss of double leaf wall systems. These studies have shown that the wall cavity and sound absorption material placed within the cavity play a crucial role in the sound transmission through these systems. However, the influence of the wall cavity on the sound transmission loss is not fully understood. The purpose of this research is to obtain a comprehensive understanding of the role played by the wall cavity and any

Abstract:

Low frequency noise transmission between dwellings is an increasing problem due to home entertainment systems with enhanced bass responses. The problem is exacerbated since there are not presently available methods of measurement, rating and prediction appropriate for low frequency sound in rooms. A review of the classical theory of sound insulation and room acoustics has shown that both theories are not applicable. In fact, the sound insulation of party walls at low frequencies is strongly dependent on the modal characteristics of the sound fields of the two separated rooms, and of the party

Abstract:

This licentiate thesis deals with the topic of variations and uncertainties in building acoustic parameters for lightweight timber constructions. A higher safety margin to the legal requirements is needed to compensate for acoustical uncertainties, which leads to higher costs. Building costs can be reduced if the variations can be identified and controlled. The project was limited to industrially prefabricated timber frame based volumes and massive timber based plate elements. This thesis is based on the work reported in three papers (A, B and C). In paper A, the variations in impact and airbo

Abstract:

Describing planned acoustic design by single number ratings yields a weak link to the subjective event, especially when the single number ratings are interpreted by others than experienced acousticians. When developing infrastructure, tools for decision making needs to address visual and aural perception. Visual perception can be addressed using game engines and this has enabled the establishment of tools for visualizations of planned constructions in virtual reality. Audio engines accounting for sound propagation in the game engine environment are steadily developing and have recently been ma

Abstract:

Impact sound insulation is one of the most important aspects when assessing sound insulation of floor constructions in buildings. For assessing the impact sound insulation of aconstruction, a standard tapping machine is used as a sound source. However, the use of the current standard tapping machine has been criticised, especially with regard to measurement of wooden joist floors since the noise spectrum generated by a tapping machine differs from the spectrum generated by actual footfall. There are insufficient low frequency components in the noise spectrum produced by the tapping machine and

This thesis examined the potential sound insulation benefit by using damping material to absorb vibrational energy along its transmission path. Statistical Energy Analysis (SEA) was used to evaluate the effect on system performance of adding damping globally, as well as its influence on individual transmission paths. Nine different theoretical models were studied using both bending only and three-wave SEA models to predict the system behaviour in different frequency regions. The results suggest that global damping treatment generally increases the sound insulation in buildings. Initial increas

Abstract:

It is difficult to predict the sound radiation from large factory roofs. The existing infinite panel theories of sound insulation are not sufficient when the sound radiates at grazing angles. It has been shown that the reason for the collapse of the theory is the well known result for the radiation efficiency. This research will present a simple analytic strip theory, which agrees reasonably well with numerical calculations for a rectangular panel. Simple analytic strip theory has lead to the conclusion that it is mainly the length of the panel in the direction of radiation, rather than its

Abstract:

The problem of unwanted noise in buildings has grown continuously over the last twenty years and impact noise through separating floors has been identified as a particularly important problem. One accepted method for improving impact sound insulation is to use floating floors in which the walking surfaces are isolated from the supporting structure by a resilient layer. Traditionally the resilient layers comprise mineral or glass fibre quilts but other materials such as flooring grade polystyrene are increasingly used. Recently, shallow profile floating floors comprising flexible open cell poly

The same principles were applied in deriving the transmission loss through periodically stiffened plates, as a proxy for corrugated panels. At the same time,

碩士<br>國立成功大學<br>土木工程學系碩博士班<br>101<br>A numerical model was generated by using ABAQUS to analyze the mechanical and acoustic properties of floors with resilient materials. First, the effects of resilient materials and face panels on the maximum tensile stress of floors subjected to uniform or concentrated loads are studied numerically. Furthermore, the acoustic properties of floors with resilient materials is investigated numerically to give the sound pressure distribution in an interior space, later switched to 1/3 octave SPL frequency domain according to ISO 717-2 standard, and then to propos

碩士<br>國立臺灣海洋大學<br>系統工程暨造船學系<br>104<br>This study is to design and develop a semi-automatic sound insulation measuring system, and analyze this system’s uncertainty of measurement using a uniform signal layer of material. We adapt the semi-automatic and manual placement measuring methods and analyze the repeatability and reproducibility of sound transmission loss data using single layer polycarbonate panels . We also take acoustical software simulation calculation and compare the experimental results using calcium silicate board. Finally, we adapt the semi-automatic measuring system and use sc

碩士<br>國立臺灣海洋大學<br>系統工程暨造船學系<br>100<br>This thesis is to design an automatic sound insulation measurement system, and compare with artificial intensity set. The design of automatic sound insulation measurement system is use the step motor to drive and PLC(Programmable Logic Controller)for programming and control. Compare with two ways of experiment in same number of measure points and same material, to find out what was the cause of the errors and improve it to achieve completely automatic control.

The habitation is becoming high-risingly alone with serious noise problem emerged from high constructionevery. Our people realize to the importance of superior quality life gradually. Because narrow people are thick in our country, the noise problem is becoming more serious from high building. The source of sound about floor impact sound always takes place on the abovestairs. It can not control by oneself, so we can only use interior decoration to achieve to soun
