音乐会要不要扩声?近来颇有争论。如果从“保真”的要求来说,当然不要扩声最好。因为电声设备总有它的噪声及各种失真,而且控制动态上也不很容易,常常由于控制上不当而破坏了演出效果。所以如果厅堂建声还过得去,观众又能保持安静,应该不用扩声。一般来说,电声是用以弥补建声上的缺陷,为适应多功能厅堂的需要,在午台艺术中常常使用扩声。七十年代中期以来,我国午台电声设备在质量上有了较明显的提高,这也是今天电声普遍应用的原因之一。近一年多,提倡社会主义精神文明,“五讲”“四美”,剧场秩序大有好转,有的音乐会已停止使用扩声,这是好现象,但就全国来看,大多数场合还是要使用扩声,音乐会也不例外。既然要用,就要用好,怎样算好?说法不一。有人说,只要开得响、不啸叫算好。 Do you want to amplify the concert? It’s quite controversial recently. If from the “fidelity” requirements, of course, not the best sound reinforcement. Because the electroacoustic device always has its noise and various kinds of distortions, and the control dynamics are not very easy, and the performance is often damaged due to improper control. So if the auditorium is built, the spectators can keep quiet and they should not have to sound reinforcement. In general, electro-acoustic is used to make up for the shortcomings of the built-in sound system. In order to meet the needs of the multi-purpose hall, PA is often used in the art of the afternoon stage. Since the mid-1970s, the quality of our Taiwan electro-acoustic equipment has been significantly improved, which is one of the reasons for the widespread application of electro-acoustic technology today. In the past year or so, advocating socialist spiritual civilization, “five stresses” and “four beautifulnesses” has greatly improved the theater order and some concerts have stopped using sound reinforcement. This is a good sign, but on a national basis, most occasions Or use the sound reinforcement, the concert is no exception. Since you want to use, we should make good use of, how to calculate? Different opinions. Someone said that as long as the sounding, not whistling considered good.
