中文摘要 | 本研究以RC樓板增設表面材試體,探討制振材料及吸音材料之配置方式對現場輕量衝擊源樓板衝擊音改善效果。依CNS 15160-7樓板衝擊音之現場量測方法,於相同空間室容積條件下,改變不同表面材之組合進行量測及計算,並參照CNS 8465-2評估曲線,將量測結果轉為單一數值參量,即加權正規化衝擊聲壓位準L'n,w及加權標準化衝擊聲壓位準L'nT,w。結果顯示,於原樓板上架高地板後可降低衝擊音單一數值參量L'n,w 18 dB,若再置入制振墊對160~800 Hz頻率改善7~11 dB,並在1k ~ 4k Hz改善1~4 dB;置入16 K玻璃纖維棉時,可改善頻率160~400 Hz之輕量衝擊源樓板衝擊音;置入制振墊比無制振墊在單一數值參量L'n,w 和L'nT,w 可改善2~5 dB;於制振墊位置置入16 K玻璃纖維棉後,可改善1~4 dB。 |
英文摘要 | This study investigates the RC floor of impact sound on raised wooden floor are placed by vibration- resistant and sound absorbing materials. These study objects used the impact sound pressure level in CNS 15160-7 field measurements method of the reduction of transmitted impact sound. The results showed that the impact sound pressure level in CNS 8465-2 floor impact sound insulation performance was insignificant, the single-number quantity L'n,w and L'nT,w. However, we fitting the ceiling and raised wooden floor could improvement floor impact sound. With the height increasing of the raised wooden floor, the single-number quantity could reduce the 18 dB. Comparison didn't put the vibration- resistant pad and put the vibration- resistant pad, each frequency could reduce more than 2 dB. Into the glass fiber could improve the frequency of 160 Hz ~ 400 Hz of the floor impact sound reduced more than 5 dB. |
