在工業降噪音(yin)(yin)(yin)設(she)備(bei)中(zhong)(zhong)，消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器是一種常用的(de)能(neng)量吸收性設(she)備(bei)。其消(xiao)(xiao)(xiao)音(yin)(yin)(yin)作(zuo)用好(hao)(hao)不好(hao)(hao)?這對(dui)用戶來說是很重要的(de)問(wen)題。下(xia)(xia)面，小編就來為大家(jia)介紹(shao)一下(xia)(xia)不同(tong)消(xiao)(xiao)(xiao)1音(yin)(yin)(yin)器的(de)消(xiao)(xiao)(xiao)音(yin)(yin)(yin)原理(li)(li)及其效(xiao)果吧。阻性消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器主要利用氣流通過(guo)途徑，多(duo)孔性吸聲(sheng)(sheng)(sheng)材料對(dui)聲(sheng)(sheng)(sheng)波產生(sheng)摩(mo)擦(ca)以及阻礙作(zuo)用，機房降噪設(she)備(bei)廠家(jia)，使聲(sheng)(sheng)(sheng)能(neng)量向熱能(neng)轉化(hua)，從而消(xiao)(xiao)(xiao)除噪音(yin)(yin)(yin)。這種工業降噪音(yin)(yin)(yin)設(she)備(bei)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)頻帶(dai)較寬，適合于中(zhong)(zhong)、高頻率的(de)噪聲(sheng)(sheng)(sheng)治理(li)(li)中(zhong)(zhong)，但對(dui)低(di)頻噪聲(sheng)(sheng)(sheng)的(de)治理(li)(li)效(xiao)果并不理(li)(li)想。
