Weak current College】 【sound engineering design principle.

An eligible project must be standardized design, a high-quality engineering is inseparable from the science strict design, scientific design is based on a number of related standards, completed a series of calculations, mastered all of device performance combined with the designer's experience, there is the science of design, engineering and construction can be successfully quality will be reliable guarantee, in particular professional audio engineering quality factors, is integrated very strong a technology, but also with the development of technology, equipment level increases, the cost of the project is getting higher and higher, so be sure to eliminate no design, no standard, no drawings of the project. Since the project's design is so important, then the sample design? this is determined from the engineering design principles, design involves five aspects of important design principles, following several aspects of the narrative.
(1) the principle of master planning
Planning a project first started to work and most importantly, it requires the designer must consider, clear, irrational, not sound will make the quality of the works, master planning, including engineering, architectural acoustics of the Hall, the architectural and decorative lighting, audio, and orientation of the project's security rationality and impact on the environment.
Which should be in the spirit of positioning for the principles of practical, do not pursue unrealistic upscale and fancy, we cannot ignore the impact of the important features of project quality;
Halls of acoustical should follow for audio equipment in the appropriate circumstances demonstrated the best results of the work of great significance, but also to the level of inspection, the designers have asked to be interviewed; after

The requirements for building decoration should be in the interest of sound and light effects built; sound light orientation should give full play to the device's performance as a starting point to reach the stage sound beautiful, light-excellent for the purpose;

Project safety and environmental impact should be based on strict compliance with the relevant State departments of statutes and regulations as the principle, particularly safety fire protection, rational use of electricity, avoiding environmental pollution is most important.

(2) acoustical principle to determine not
Professional audio engineering of acoustical primarily architectural acoustics of the Hall, the same level of the device is not a reason of high or low, are generally different acoustical conditions, no matter how excellent equipment, once placed in the acoustical conditions harsh environments, certainly not achieved good results, but will also acoustical requirements because the project requirements, and will also be affected by the quality of architectural decoration, architectural acoustic effect good Auditorium should be reasonable, sound diffusion reverb is good, there is no focus, no sound heard of vibration and noise, there is no acoustic shadow etc, acoustical requirements cannot unilaterally by the sound designer, it requires building a strong decorative and technical personnel, but due to their design ideas and requirements vary, this requires sound engineering master plan work began as early as possible, maintain regular contact with both sides in order to achieve mutual understanding and closely cooperate with each other, the reverberation time selection can be based on the nature and purpose to determine, if necessary, should draw on the experience of a number of excellent works.

(3) determine the principles of sound reinforcement forms
The so-called sound reinforcement form refers to the use of Mono, stereo or surround sound system with increased sound reinforcement, usually for the requirements of sound reinforcement sites should use a single sound, the first sound reinforcement so that not only is the savings account, and in most of the background music sound reinforcement applications up way, but to the entire sound reinforcement area reached the stereo effect is quite difficult, this requires a design-time configuration of the device must be reasonable, the speaker set-up to consider its electroacoustic I, finally also need according to the specific sound field is adjusted; surround sound system comes from film sound reinforcement systems, it environments and equipment requirements are special 100 often, domestic and international has specialized in standards provides that strictly speaking cinema surround sound system is independent of the General sound system, so if the movie surround sound is not too understand the words do not lightly add so-called surround sound system, back to unreasonable surround sound configuration not only could not form the surround and destroy the sound field, interfere with the sound play, the result will be a time-consuming and frustrating; however, in recent years the rise of Home AV system, more and more people on the so-called "surround sound" requires it, so you can request not high karaoke rooms, small Auditorium, etc for simple configuration.

(4) lighting principles identified in the form of
Relative to the sound, the lights of the professional level is even higher, so in general are described in the books and articles, only some technical articles are also more practical theory is poor, the reason is the lighting of classification like performance equipment and audio recording equipment, usage, premises, lighting design and engineering is completely different, the stage performance with lights, in the Opera Academy have relevant professional; and television with lighting in film school and Broadcasting Institute and a separate description; as for theatrical performances and entertainment lighting effect, which is more of a figure, if to please and art groups of lights ', they will tell a lot about light, this required in professional audio engineering design of the lighting must be careful, especially in relation to the stage and Studio specialized purpose project designers must conscientiously study and, if necessary, professional design unit to assist.

(5) equipment positioning determination principles
With the above principles determine the last should be the positioning of the devices in the project. Orientation purposes is in certain investment of overall planning, reference point is at the market price of the equipment, there are important point is: equipment positioning of consistency. About equipment positioning of consistency problems, engineering and technical personnel will often experience, often because of cost reasons, equipment performance is not the reason, why not configured properly, and so causing equipment positioning are inconsistent, the result will be: system instability or system level affected by the restriction of certain equipment. Therefore, maintaining equipment positioning of consistency to a certain extent, determine the final quality of the project. In addition, because the device orientation related to cost and fundingContradiction. Works will be on this debate, so designers should and financial staff work together closely to cost accounting, namely to ensure the prices on the dominant and guarantee the economic interests of the company. Especially abroad in recent years many high-quality brands of specialized equipment gradually entering various agents within a highly competitive, so in many cases, if the selection done right, you can locate the same, a reasonable allocation of costs to be reduced, both are very satisfied with the project.
