1、聲的原則：混響合理，聲音擴(kuò)散性好沒有聲聚焦、沒有可聞的振動噪聲、沒有死聲點。
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(nèi)裝修應(yīng)注意事項：色調(diào)不能太昏暗， 導(dǎo)致會議或演出時出現(xiàn)不好的效果，避免擴(kuò)聲區(qū)域內(nèi)出現(xiàn)中空較大或支撐較差的腔體結(jié)構(gòu)，避免出現(xiàn)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(nèi)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:在觀眾席的各個座位上聽到的聲音響度應(yīng)比較均勻。通過音質(zhì)設(shè)計， 應(yīng)該能使觀眾席各個區(qū)域的聲壓級差別不太大，室內(nèi)聲場不均勻度應(yīng)控制在高低約3dB之內(nèi)。
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、滿足訊噪比要求:噪聲對人們的正常聽覺產(chǎn)生干擾和掩蔽作用。不同用途的室內(nèi)聽音環(huán)境，其允許的噪聲級別不盡相同， 訊噪比應(yīng)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(nèi)各處頻率響應(yīng)均衡:室內(nèi)音響系統(tǒng)應(yīng)保證各處頻率響應(yīng)均衡，如果室內(nèi)存在聲聚焦、死聲點、駐波、聲共振等聲學(xué)問題，就會破壞頻率均衡。
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：選擇合適的混響時間。
7. Reasonable proportion of sound construction: Choose the appropriate reverberation time.
