20世紀50~60年(nian)代(dai)，當(dang)(dang)時(shi)(shi)國(guo)內吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)品(pin)種(zhong)很少，木(mu)(mu)絲(si)板(ban)是(shi)主要的(de)(de)(de)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)和隔(ge)(ge)(ge)熱(re)保(bao)溫材(cai)料(liao)(liao)。在(zai)(zai)工業和民(min)用(yong)建(jian)筑(zhu)中獲得廣泛(fan)的(de)(de)(de)應用(yong)。特別是(shi)常見在(zai)(zai)電影(ying)院、劇院、錄音室(shi)(shi)、演播室(shi)(shi)、廣播室(shi)(shi)、電話室(shi)(shi)、會議(yi)室(shi)(shi)、報告(gao)廳(ting)、禮(li)堂(tang)等建(jian)筑(zhu)中使用(yong)，起(qi)(qi)控制混響時(shi)(shi)間的(de)(de)(de)作(zuo)(zuo)用(yong)。如20世紀60年(nian)代(dai)初，同(tong)濟大學新(xin)建(jian)的(de)(de)(de)約(yue)4000座大禮(li)堂(tang)，長60m、寬40 m拱形鋼筋混凝土(tu)薄殼屋頂(ding)，兩(liang)側墻(qiang)安裝玻璃窗，屋頂(ding)和前后墻(qiang)面(mian)選用(yong)木(mu)(mu)絲(si)板(ban)作(zuo)(zuo)為(wei)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)，控制廳(ting)內的(de)(de)(de)混響時(shi)(shi)間以及拱形屋頂(ding)的(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)聚(ju)焦，為(wei)擴聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)提供(gong)良好的(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)環(huan)境。其屋頂(ding)鋪設木(mu)(mu)絲(si)板(ban)除(chu)起(qi)(qi)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)作(zuo)(zuo)用(yong)外，還(huan)起(qi)(qi)隔(ge)(ge)(ge)熱(re)保(bao)溫作(zuo)(zuo)用(yong)。該禮(li)堂(tang)內的(de)(de)(de)木(mu)(mu)絲(si)板(ban)使用(yong)40多年(nian)，除(chu)表(biao)(biao)面(mian)做過噴涂維修之(zhi)外，木(mu)(mu)絲(si)板(ban)仍保(bao)持完整，這表(biao)(biao)明木(mu)(mu)絲(si)板(ban)具有相當(dang)(dang)的(de)(de)(de)耐久性。同(tong)時(shi)(shi)木(mu)(mu)絲(si)板(ban)還(huan)用(yong)于(yu)水(shui)泵房、風機房進(jin)行吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)降噪(zao)。由于(yu)木(mu)(mu)絲(si)板(ban)在(zai)(zai)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)中具有較高強度和剛度，表(biao)(biao)面(mian)抹灰后能(neng)起(qi)(qi)隔(ge)(ge)(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)作(zuo)(zuo)用(yong)，又是(shi)一種(zhong)輕質隔(ge)(ge)(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)，可(ke)用(yong)于(yu)室(shi)(shi)內分隔(ge)(ge)(ge)墻(qiang)
