20世紀50~60年(nian)代，當時(shi)(shi)國內吸(xi)(xi)聲(sheng)(sheng)材(cai)料(liao)品(pin)種很少，木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)是(shi)(shi)主要(yao)的(de)(de)吸(xi)(xi)聲(sheng)(sheng)材(cai)料(liao)和(he)隔(ge)熱保溫材(cai)料(liao)。在(zai)工業(ye)和(he)民用(yong)(yong)(yong)建筑中(zhong)(zhong)獲(huo)得廣泛的(de)(de)應用(yong)(yong)(yong)。特別是(shi)(shi)常見(jian)在(zai)電(dian)影院、劇院、錄音室(shi)、演播室(shi)、廣播室(shi)、電(dian)話室(shi)、會議室(shi)、報(bao)告廳、禮(li)(li)堂等(deng)建筑中(zhong)(zhong)使用(yong)(yong)(yong)，起控制(zhi)混(hun)響時(shi)(shi)間的(de)(de)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)(yong)。如20世紀60年(nian)代初，同(tong)濟(ji)大(da)學新(xin)建的(de)(de)約4000座大(da)禮(li)(li)堂，長60m、寬40 m拱(gong)形鋼筋混(hun)凝土(tu)薄(bo)殼屋頂(ding)，兩側墻安裝玻(bo)璃窗，屋頂(ding)和(he)前后墻面(mian)選(xuan)用(yong)(yong)(yong)木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)作(zuo)(zuo)(zuo)(zuo)為(wei)吸(xi)(xi)聲(sheng)(sheng)材(cai)料(liao)，控制(zhi)廳內的(de)(de)混(hun)響時(shi)(shi)間以及拱(gong)形屋頂(ding)的(de)(de)聲(sheng)(sheng)聚焦，為(wei)擴聲(sheng)(sheng)提供良好的(de)(de)聲(sheng)(sheng)環(huan)境。其屋頂(ding)鋪(pu)設木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)除起吸(xi)(xi)聲(sheng)(sheng)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)(yong)外(wai)，還(huan)起隔(ge)熱保溫作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)(yong)。該禮(li)(li)堂內的(de)(de)木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)使用(yong)(yong)(yong)40多年(nian)，除表面(mian)做過噴涂維修之外(wai)，木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)仍保持完整，這表明木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)具有相當的(de)(de)耐久(jiu)性。同(tong)時(shi)(shi)木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)還(huan)用(yong)(yong)(yong)于(yu)水(shui)泵房(fang)、風(feng)機(ji)房(fang)進行吸(xi)(xi)聲(sheng)(sheng)降噪。由(you)于(yu)木(mu)絲(si)(si)(si)(si)(si)板(ban)(ban)(ban)在(zai)吸(xi)(xi)聲(sheng)(sheng)材(cai)料(liao)中(zhong)(zhong)具有較(jiao)高強度和(he)剛度，表面(mian)抹灰后能起隔(ge)聲(sheng)(sheng)作(zuo)(zuo)(zuo)(zuo)用(yong)(yong)(yong)，又是(shi)(shi)一種輕質(zhi)隔(ge)聲(sheng)(sheng)材(cai)料(liao)，可用(yong)(yong)(yong)于(yu)室(shi)內分隔(ge)墻
