A Research On The Sound System Design Of A Ballroom

In the recent years, with the rise of our nation's economy, with the development of the social infrastructure, with the improvement of people's living standard and with the globliaztion of the pursuit of the culture and entertainment quality, the sound system engineering of a ballroom remains a high development speed so as to meet the glowing demands.The sound system design of a ballroom belongs to the architecture and electricity engineering system. It consists of the architecture acoustics design, the sound reinforcement design, the system building and the system adjustment. These three sections attach closely to each other and cooperate together. This dissertation follows the linearity programming sequence of the sound system design, according to the possibility in real consturciton, making a elaborate and systematic discuss of the early filed trip, the targeting design, the adjustment and improvement of the architecture acoustical environment; the mid-turn sound equipment selection, the equipment configuration, the power supply and the shield, the quoted price and the bid determination; the upper sound system building and adjustment, and the feedback of investigation research.A professional sound system design requires the academic theoretical support from the comrephensive implementation of the intersubjects. A professional sound system of a ballroom combines the electro-acoustics, the electricity, the architecture acoustics, the hearing physilology, the musicology, the operation management and some other subjects. This dissertation forms a practical implemented guiding sound system design project in a precise scientific systematic way. Each section is a systematic individual, meanwhile all the sections are linked to each other.After fulfilling the analysis of "What" in the system design, this dissertation makes a further explanation and argumentation to "How " and "Why" from appearance to essence, form history to reality, which is different from the common scientific term explanation. In the practice research, many cases and data are quoted, in order to assist the dissertation to estimate, to discover, to raise and to resolve some representative preoblems in the sound system design, so that everything can be rooted from the principle.The total solution of the sound system of a ballroom is the the core of the research. The professional sound system design is the stand of the idea. This dissertation attaches an importance to the front-end concept and to the designer in the overall situation. It precisely discussed the advantage of the "Juxtaposed Combination of Speakers" in a scientific way; it creatively introduces the "Reverse Dirction Method" in system flow design; it comes up with the "Microphone Q Value Mehod" and demonstrates the guiding significance of which to elimiante the feedback and to choose the microphone in common practice for the 1 st time.Baesd on the technique success, this dissertation echoes the intention and significance of the front-end design via the practical investigation research and adjustment. In addition, the artistic process and complementarity offers a convincing support and guarantee for the ultimate realizement of the whole sound system. Since then, the consolidation of technique implementation and the artistic performance have been achieved.
