舞台音响特点是什么?舞台众多企业都有,规模不一,那都会有那些特点呢?而且如何抓住这些特点打造一个开会效果很好的舞台呢?以下是荣锋音响设计师非常认同的观点。
1、舞台音响特点
在音响行业中,各种舞台音响系统是很常见的。在设计该类音响系统时,必需首先明确其功能要求、体形和席位的布置等情况,因此,这些情况对扩声的影响是很大的。
舞台主要是进行语言扩声的,合适的声压级、高的传声增益和语言清楚度以及小的声压级不平均度是其主要技术要求,特别是要有高的传声增益。
舞台的体形及舞台内席位布置往往是多种多样的。例如大量的中、小型舞台体形不理想,装修也没有考虑声学处理。为了获得高的清楚度和传声增益,扬声器的选择和布置就必需特别加以考虑。
2、舞台音响系统设计要点
在设计扩声系统时要把进步系统的传声增益作为设计重点;特别是中、小型舞台。这是由于中、小型舞台要取得满足的声压级并不难题,但是因为以上所说的种种原因,要取得高的传声增益却不轻易,所以在使用过程中需要对发话器进行调节。
要进步传声增益,除了改善声学环境前提外,应着重考虑扬声器的布置和投向、扬声器与发话器的相对位置以及加装反馈按捺设备(频移器、反馈按捺器、均衡器等)。
中型舞台以分散布置小功率扬声器为主,它能够避免系统降低语言清楚度,甚至在有些席位上泛起回声或多重声的现象。

what sound stage is characterized by many stage companies have, of varying scale, and that it will have those characteristics and how to take advantage of these features to create the effect of a good stage to meet it the following is a view rongfeng sound designer very identity. 1, stage sound characteristics in the audio industry, various stage sound systems are very common. in the design of the class sound system, it must first clarify its functional requirements, case shape and arrangement of seats and so, therefore, the impact of these circumstances on the sound is great. the main stage is the language of sound, suitable spl, high gain before feedback and linguistic clarity and low sound pressure level is not the average of its main technical requirements, in particular, have high gain before feedback. stage shape and arrangement of seats in the arena are often varied. for example, a large number of medium and small stage is not ideal shape, decoration did not consider the acoustic treatment. in order to obtain a high degree of clarity and sound transmission gain, the selection and arrangement of the speakers on the required special consideration. 2, stage sound system design features in the audio gain during the progress of the system should sound reinforcement system design as a design focus; in particular, the small stage. this is because, the small stage to get to meet the spl is not the problem, but because of various reasons mentioned above, to achieve high gain before feedback is not easy, so in the course of the speaker is required to be adjusted. sound transmission gain to progress, in addition to improving the acoustic environmental conditions, but should consider the relative positions of the speaker arrangement and orientation, and the speaker's speech feedback inhibition installation device (shifter, feedback inhibition, equalizers, etc.). small and medium-sized power stage arranged to disperse the main speaker, it can avoid system reduces the clarity of the language, and even thrown phenomenon or multiple echo sound on some seats.
