论文部分内容阅读
电声学和建筑声学是声学的二个专业分支,在近代观众厅的扩声系统设计中,这两项专业分支就融为一体了,从系统的观点看,观众厅建筑音质设计应作为扩声系统的一个组成部分,因此作为从事扩声系统设计的电声工程师来说,需要了解观众厅建筑音质设计的专业技术知识。本讲座除了介绍该方面的专业知识外,还引用了大量的国内外厅堂设计实例及实测数据,因此对于厅堂音质设计的同志颇有教益。本讲座分两大部分用四讲刊出,第一部分叙述响度、混响时间、前次(早期)反射声、扩散等观众厅性能参数的设计关系(分三讲);第二部分叙述观众厅体积、尺寸比例、体型、吸声处理等建筑设计参数的常规考虑的设计步骤(第四讲)。至于电声系统设计、扬声器和传声器选择、布置将另有文章介绍。
Electroacoustics and architectural acoustics are two professional branches of acoustics. In the design of the sound reinforcement system of modern auditoriums, these two professional branches are integrated. From a system point of view, auditorium building sound quality design should be used as a As an integral part of the sound system, as an electro-acoustic engineer working in sound reinforcement system design, it is necessary to know the professional technical knowledge of auditorium building sound quality design. In addition to introducing this area of expertise, this lecture also quotes a large number of design examples and measured data from domestic and foreign halls, which is of great benefit to the comrades in the design of halls. This lecture is divided into two parts and is published in four parts. The first part describes the design relationship of loudspeaker, reverberation time, previous (early) reflected sound and diffusion and other performance parameters of the auditorium (in three parts); the second part describes the auditorium Volume, size ratio, size, sound absorption and other architectural design parameters of the conventional design considerations (fourth lecture). As for electro-acoustic system design, speaker and microphone selection, layout will be another article introduction.
