1、声的原则：混响合理，声音扩散性好没有声聚焦、没有可闻的振动噪声、没有死声点。
1. The principle of sound: reasonable reverberation, good sound diffusion, no sound focusing, no audible vibration noise, and no dead sound points.
2、室内装修应注意事项：色调不能太昏暗， 导致会议或演出时出现不好的效果，避免扩声区域内出现中空较大或支撑较差的腔体结构，避免出现大面积玻璃窗。
2. Precautions for interior decoration: The color tone should not be too dim, which may result in poor results during meetings or performances. Avoid cavity structures with large voids or poor support in the sound reinforcement area, and avoid large glass windows.
3、室内声学特性的基本要求：具有合适的响度大于103诲叠。
3. Basic requirements for indoor acoustic characteristics: having a suitable loudness greater than 103dB.
4、声能分布均匀:在观众席的各个座位上听到的声音响度应比较均匀。通过音质设计， 应该能使观众席各个区域的声压级差别不太大，室内声场不均匀度应控制在高低约3dB之内。
4. Uniform distribution of sound energy: The loudness of the sound heard from each seat in the audience should be relatively uniform. Through sound quality design, it should be possible to ensure that the sound pressure levels in various areas of the audience are not significantly different, and the unevenness of the indoor sound field should be controlled within about 3dB.
5、满足讯噪比要求:噪声对人们的正常听觉产生干扰和掩蔽作用。不同用途的室内听音环境，其允许的噪声级别不尽相同， 讯噪比应该大于30dB。
5. Meet the signal-to-noise ratio requirement: Noise has an interference and masking effect on people's normal hearing. Indoor listening environments for different purposes may have different allowable noise levels, and the signal-to-noise ratio should be greater than 30dB.
6、保证室内各处频率响应均衡:室内音响系统应保证各处频率响应均衡，如果室内存在声聚焦、死声点、驻波、声共振等声学问题，就会破坏频率均衡。
6. Ensure balanced frequency response in all parts of the room: The indoor sound system should ensure balanced frequency response in all parts. If there are acoustic problems such as sound focusing, dead spots, standing waves, and resonance inside the room, it will disrupt frequency balance.
7、建声合理比例：选择合适的混响时间。
7. Reasonable proportion of sound construction: Choose the appropriate reverberation time.
