影(ying)音(yin)室的(de)(de)(de)墻(qiang)壁一般多是前墻(qiang)硬左(zuo)右側墻(qiang)吸(xi)(xi)(xi)音(yin)后墻(qiang)擴散的(de)(de)(de)原則(ze)去(qu)裝(zhuang)修(xiu)。聆聽(ting)空(kong)(kong)間(jian)中(zhong)要特別(bie)注意不要用(yong)薄(bo)板來(lai)釘空(kong)(kong)腔墻(qiang)或分隔空(kong)(kong)間(jian),因為薄(bo)木(mu)板厚度多在0.5cm~3cm,3cm以上的(de)(de)(de)厚度很少見,3cm板吸(xi)(xi)(xi)125Hz頻率(lv)(lv)(lv)相當高,有(you)0.28吸(xi)(xi)(xi)收率(lv)(lv)(lv),頻率(lv)(lv)(lv)越(yue)(yue)往上吸(xi)(xi)(xi)音(yin)率(lv)(lv)(lv)就(jiu)(jiu)越(yue)(yue)下降。板子(zi)(zi)越(yue)(yue)薄(bo)時,125Hz的(de)(de)(de)吸(xi)(xi)(xi)音(yin)率(lv)(lv)(lv)就(jiu)(jiu)越(yue)(yue)低(di),但250Hz的(de)(de)(de)吸(xi)(xi)(xi)音(yin)率(lv)(lv)(lv)就(jiu)(jiu)越(yue)(yue)高。家庭裝(zhuang)修(xiu)中(zhong),多是用(yong)2cm板來(lai)分隔房(fang)間(jian),而且板子(zi)(zi)后面還有(you)空(kong)(kong)腔,空(kong)(kong)腔會令吸(xi)(xi)(xi)音(yin)率(lv)(lv)(lv)增(zeng)加,這使得中(zhong)低(di)頻的(de)(de)(de)量感(gan)更(geng)少,聲音(yin)更(geng)單(dan)薄(bo)。
