中文摘要 | 本試驗目的在比較木造與混凝土磚造試驗屋之隔音性能,由於本試驗木造與混凝土磚造兩棟建築物為獨立式無共同的牆壁,測試方法應用JIS A 1417建築物現場音壓位準差測定之改良法-外部音源法,儀器包括音壓位準全音度頻帶分析器(RION NA-29)與帶域雜音發生器(RION SF-05),揚聲器(RION SS-02)。針對木造與混凝土磚造試驗屋之測試結果摘示如下:1.本試驗A、B兩棟為分離的建築物無共同的牆壁,故JIS A 1417建築物現場音壓位準差的測試方法宜改採外部音源法。2.門、窗之隔音性能測試結果顯示,木造優於混凝土磚造之結構。但在外壁之隔音性能,則兩者甚為相似。3.隔音性能若以500 Hz中心頻率為基準,則木造試驗屋依序:門(23 dB)>外壁(17 dB)>窗(15 dB);混凝土磚造試驗屋依序:外壁(16 dB)>門(15 dB)>窗(13 dB)。 |
英文摘要 | The purpose of this study was to compare the properties of sound transmission between wooden and reinforced concrete testing houses. Because both of them were independent and had no conjoint wall , The Outer Sound Source Method that was modified from JIS A 1417 Method for Field Measurement of Sound Pressure Level Difference was applied. During the experiment, the instrumentation system of sound level meter octaver bandana1yzer (RION NA-29), random noise generater (RION SF-05) and speaker (RION SS-02) were used. The results are summarized as follows: 1. Neither wooden nor reinforced concrete testing houses has anγconjoint wall, the Outer Sound Source Method was substituted for 1IS A 1417 Method for Field Measurement of Sound Pressure Level. 2. Wooden testing-house showed higher sound pressure difference of testing house by door and window. Sound pressure difference by wall was nearly the same between the two types of testing houses. 3. Using sound pressure difference at 500 Hz as an index , sound pressure difference of wooden testing house: door (23dB) > wall (17dB) > window (1SdB). Sound pressure difference of reinforced concrete testing house: wall (16dB) > door (1SdB) > window (13dB). |
