专业音响的声学特性不仅要满足声学特性

专业音响的声学特性不仅要满足声学特性指标国家标准的要求，还要满足主观听音的要求，因为声学特性指标不能完全体现实际声音效果，声音的好坏最终是由人的主观听音感觉来决定，在声学设计时，电声与建声设计应良好配合，满足以下主观听音要求：合适的响度。
The acoustic characteristics of professional sound systems should not only meet the requirements of national standards for acoustic characteristics, but also meet the requirements of subjective listening, because acoustic characteristics cannot fully reflect the actual sound effect. The quality of sound is ultimately determined by the subjective listening sensation of humans. In acoustic design, electrical and architectural design should cooperate well to meet the following subjective listening requirements: appropriate loudness.
响度是实际听音的强度感觉，它与扩声系统的最大声压级指标有直接关系，对于演出来讲，只有达到足够的响度，才能使音响效果得以充分表现。系统输出功率、音箱的摆放位置等将直接决定听音区域的响度状态：高解析度。
Loudness is the perceived intensity of actual listening, which is directly related to the maximum sound pressure level indicator of the sound reinforcement system. In terms of performance, only by achieving sufficient loudness can the sound effect be fully demonstrated. The output power of the system and the placement of the speaker will directly determine the loudness status of the listening area: high resolution.
作为演讲使用时，必须保证语言的可懂度，如果人们不能听清演讲者的语言，就会影响演讲的效果。因此，在电声系统设计时要充分考虑提高语言可懂度：足够的丰满度。
When used as a speech, it is necessary to ensure the comprehensibility of the language. If people cannot hear the speaker's language clearly, it will affect the effectiveness of the speech. Therefore, in the design of electroacoustic systems, it is necessary to fully consider improving language intelligibility: sufficient richness.
