1、聲的原則：混響合理，聲音擴散性好沒(méi)有聲聚焦、沒(méi)有可聞的振動(dòng)噪聲、沒(méi)有死聲點(diǎn)。
1. The principle of sound: reasonable reverberation, good sound diffusion, no sound focusing, no audible vibration noise, and no dead sound points.
2、室內裝修應注意事項：色調不能太昏暗， 導致會(huì )議或演出時(shí)出現不好的效果，避免擴聲區域內出現中空較大或支撐較差的腔體結構，避免出現大面積玻璃窗。
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、室內聲學(xué)特性的基本要求：具有合適的響度大于103dB。
3. Basic requirements for indoor acoustic characteristics: having a suitable loudness greater than 103dB.
4、聲能分布均勻:在觀(guān)眾席的各個(gè)座位上聽(tīng)到的聲音響度應比較均勻。通過(guò)音質(zhì)設計， 應該能使觀(guān)眾席各個(gè)區域的聲壓級差別不太大，室內聲場(chǎng)不均勻度應控制在高低約3dB之內。
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、滿(mǎn)足訊噪比要求:噪聲對人們的正常聽(tīng)覺(jué)產(chǎn)生干擾和掩蔽作用。不同用途的室內聽(tīng)音環(huán)境，其允許的噪聲級別不盡相同， 訊噪比應該大于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、保證室內各處頻率響應均衡:室內音響系統應保證各處頻率響應均衡，如果室內存在聲聚焦、死聲點(diǎn)、駐波、聲共振等聲學(xué)問(wèn)題，就會(huì )破壞頻率均衡。
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、建聲合理比例：選擇合適的混響時(shí)間。
7. Reasonable proportion of sound construction: Choose the appropriate reverberation time.
