影音(yin)(yin)(yin)室的(de)墻(qiang)壁(bi)一般(ban)多(duo)是前墻(qiang)硬左右側墻(qiang)吸(xi)(xi)(xi)音(yin)(yin)(yin)后(hou)墻(qiang)擴散(san)的(de)原(yuan)則去(qu)裝修。聆(ling)聽空(kong)(kong)間中要(yao)特(te)別注意不要(yao)用薄(bo)板(ban)來釘(ding)空(kong)(kong)腔(qiang)墻(qiang)或分隔(ge)空(kong)(kong)間,因為薄(bo)木板(ban)厚度(du)多(duo)在0.5cm~3cm,3cm以上的(de)厚度(du)很少見,3cm板(ban)吸(xi)(xi)(xi)125Hz頻(pin)率(lv)(lv)相(xiang)當高,有0.28吸(xi)(xi)(xi)收率(lv)(lv),頻(pin)率(lv)(lv)越(yue)往上吸(xi)(xi)(xi)音(yin)(yin)(yin)率(lv)(lv)就(jiu)(jiu)越(yue)下降(jiang)。板(ban)子越(yue)薄(bo)時,125Hz的(de)吸(xi)(xi)(xi)音(yin)(yin)(yin)率(lv)(lv)就(jiu)(jiu)越(yue)低,但250Hz的(de)吸(xi)(xi)(xi)音(yin)(yin)(yin)率(lv)(lv)就(jiu)(jiu)越(yue)高。家(jia)庭裝修中,多(duo)是用2cm板(ban)來分隔(ge)房間,而(er)且板(ban)子后(hou)面還(huan)有空(kong)(kong)腔(qiang),空(kong)(kong)腔(qiang)會令吸(xi)(xi)(xi)音(yin)(yin)(yin)率(lv)(lv)增加,這(zhe)使得中低頻(pin)的(de)量(liang)感更少,聲(sheng)音(yin)(yin)(yin)更單薄(bo)。
