主(zhu)要是利用(yong)多孔(kong)(kong)吸聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)來降低(di)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)(de)(de)。把吸聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)固定在氣流通道(dao)的(de)(de)(de)(de)內壁上(shang)(shang)(shang)或按照一(yi)(yi)(yi)定方式在管(guan)(guan)道(dao)中(zhong)排列，就(jiu)構(gou)成(cheng)(cheng)了(le)阻(zu)(zu)性(xing)(xing)(xing)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)。當(dang)(dang)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)進(jin)入阻(zu)(zu)性(xing)(xing)(xing)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)時(shi)，一(yi)(yi)(yi)部分聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)能在多孔(kong)(kong)材(cai)料(liao)(liao)的(de)(de)(de)(de)孔(kong)(kong)隙中(zhong)摩擦而(er)轉化成(cheng)(cheng)熱能耗散掉，使通過消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)的(de)(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)減弱。阻(zu)(zu)性(xing)(xing)(xing)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)就(jiu)好象電(dian)(dian)(dian)學(xue)上(shang)(shang)(shang)的(de)(de)(de)(de)純電(dian)(dian)(dian)阻(zu)(zu)電(dian)(dian)(dian)路，吸聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)(liao)類(lei)似于電(dian)(dian)(dian)阻(zu)(zu)。因(yin)此，人(ren)們(men)就(jiu)把這種(zhong)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)稱(cheng)(cheng)為(wei)阻(zu)(zu)性(xing)(xing)(xing)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)。阻(zu)(zu)性(xing)(xing)(xing)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)(qi)對中(zhong)高頻(pin)(pin)(pin)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)效(xiao)果好、對低(di)頻(pin)(pin)(pin)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)效(xiao)果較差。是由(you)突變(bian)界面(mian)的(de)(de)(de)(de)管(guan)(guan)和室(shi)(shi)(shi)(shi)組合而(er)成(cheng)(cheng)的(de)(de)(de)(de)，好象是一(yi)(yi)(yi)個(ge)(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)學(xue)濾波(bo)(bo)(bo)(bo)器(qi)(qi)，與電(dian)(dian)(dian)學(xue)濾波(bo)(bo)(bo)(bo)器(qi)(qi)相似，每(mei)一(yi)(yi)(yi)個(ge)(ge)帶(dai)管(guan)(guan)的(de)(de)(de)(de)小(xiao)室(shi)(shi)(shi)(shi)是濾波(bo)(bo)(bo)(bo)器(qi)(qi)的(de)(de)(de)(de)一(yi)(yi)(yi)個(ge)(ge)網(wang)孔(kong)(kong)，管(guan)(guan)中(zhong)的(de)(de)(de)(de)空氣質(zhi)量相當(dang)(dang)于電(dian)(dian)(dian)學(xue)上(shang)(shang)(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)感和電(dian)(dian)(dian)阻(zu)(zu)，稱(cheng)(cheng)為(wei)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)質(zhi)量和聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)阻(zu)(zu)。小(xiao)室(shi)(shi)(shi)(shi)中(zhong)的(de)(de)(de)(de)空氣體積相當(dang)(dang)于電(dian)(dian)(dian)學(xue)上(shang)(shang)(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)容(rong)，稱(cheng)(cheng)為(wei)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)順。與電(dian)(dian)(dian)學(xue)濾波(bo)(bo)(bo)(bo)器(qi)(qi)類(lei)似，每(mei)一(yi)(yi)(yi)個(ge)(ge)帶(dai)管(guan)(guan)的(de)(de)(de)(de)小(xiao)室(shi)(shi)(shi)(shi)都(dou)有(you)自(zi)己的(de)(de)(de)(de)固有(you)頻(pin)(pin)(pin)率。當(dang)(dang)包含有(you)各(ge)種(zhong)頻(pin)(pin)(pin)率成(cheng)(cheng)分的(de)(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)進(jin)入第(di)一(yi)(yi)(yi)個(ge)(ge)短管(guan)(guan)時(shi)，只(zhi)有(you)在第(di)一(yi)(yi)(yi)個(ge)(ge)網(wang)孔(kong)(kong)固有(you)頻(pin)(pin)(pin)率附近的(de)(de)(de)(de)某些(xie)頻(pin)(pin)(pin)率的(de)(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)才能通過網(wang)孔(kong)(kong)到(dao)達第(di)二(er)個(ge)(ge)短管(guan)(guan)口，而(er)另外(wai)一(yi)(yi)(yi)些(xie)頻(pin)(pin)(pin)率的(de)(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)則(ze)不可(ke)能通過網(wang)孔(kong)(kong)．只(zhi)能在小(xiao)室(shi)(shi)(shi)(shi)中(zhong)來回反射，因(yin)此，我們(men)稱(cheng)(cheng)這種(zhong)對聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)(bo)有(you)濾波(bo)(bo)(bo)(bo)功能的(de)(de)(de)(de)結構(gou)為(wei)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)學(xue)濾波(bo)(bo)(bo)(bo)器(qi)(qi)。選取適(shi)當(dang)(dang)的(de)(de)(de)(de)管(guan)(guan)和室(shi)(shi)(shi)(shi)進(jin)行組合．就(jiu)可(ke)以濾掉某些(xie)頻(pin)(pin)(pin)率成(cheng)(cheng)分的(de)(de)(de)(de)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，從而(er)達到(dao)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)。抗性(xing)(
