KTV包间内的噪声污染主要在低频63 Hz～125 Hz，噪声级一般可以超过105 dB，其噪声源边界排放噪声也超出了相应的限值，针对KTV包间的噪声污染，介绍了目前比较成熟的噪声处理方案。首先KTV包间内的墙壁、顶棚、门和地板隔声处理；其次是介绍包间采取的吸声材料和广泛应用的吸声结构；包间音箱设备的隔振处理；包间内减少声波的泄露；以及新型局域共振声子晶体的理论及应用。
KTV包間內的譟聲汙染主要在低頻63 Hz～125 Hz，譟聲級一般可以超過105 dB，其譟聲源邊界排放譟聲也超齣瞭相應的限值，針對KTV包間的譟聲汙染，介紹瞭目前比較成熟的譟聲處理方案。首先KTV包間內的牆壁、頂棚、門和地闆隔聲處理；其次是介紹包間採取的吸聲材料和廣汎應用的吸聲結構；包間音箱設備的隔振處理；包間內減少聲波的洩露；以及新型跼域共振聲子晶體的理論及應用。

In KTV rooms, the noise pollution is mainly reflected in the low frequency range between 63 Hz and 125 Hz, the volume can reach 105 dB or more, and the noise level on the noise source boundary can exceed the critical value. In this paper, some successful schemes for low-frequency noise processing in KTV rooms are introduced, including sound insulations of walls, ceilings, doors and floors of the KTV rooms; the application of sound-absorption materials and structures and their vibration isolation characteristics;the vibration isolation of audio devices;acoustic leakage reduction in the rooms etc. Finally, the theory and application of phononic crystal plate with periodic novel spiral resonators are introduced.
