摘要

聲音對人耳的影響主要是中頻及中低頻，人耳聽力會隨年齡增長而衰退，年長的人聽覺對於低頻聲音更為敏感，纖維與表面紋路對於吸音效果有不同的影響，本研究係將不織布疊合3 mm、6 mm、9 mm不同孔徑三明治板材組合測試吸音效果，得到當三明治孔徑大於前面的三明治板材孔徑，在1000Hz頻率的吸音率達0.80。當使用在建築隔音用品時，防火與強度檢測不織布三明治板材燃燒後碳化長度在4cm以內，在三明治板材耐衝擊強度測試方面，得到最佳尺寸為6mm/3mm三明治板材耐衝擊強力達18.9J。

The effect of the sound on the human ear is mainly intermediate frequency and low frequency, ear hearing will grow with age and decline, older people are more sensitive to low-frequency sound, because the fiber and the surface lines for the sound effects have different effects, the study system combines nonwoven fabric with 3mm, 6mm, 9mm different diameter sandwich panels to measure the sound absorption effect, when the sandwich aperture is larger than the front of the sandwich plate aperture, In the 1000Hz frequency of the sound absorption rate of 0.80. When used in building sound insulation products, fire and strength detection Nonwovens sandwich plate after burning carbonization within 4cm, in the sandwich plate impact strength test, get the best size of 6mm / 3mm sandwich sheet impact strength of 18.9J.
