江西噪音治理
噪(zao)音(yin)(yin)治(zhi)理(li)(li)的目標是(shi)降(jiang)低噪(zao)音(yin)(yin)污染,但實現這一(yi)目標并(bing)不(bu)是(shi)一(yi)蹴而就的。針對不(bu)同的噪(zao)音(yin)(yin)污染源,需要采取不(bu)同的治(zhi)理(li)(li)措施,并(bing)在長期的實踐(jian)中不(bu)斷優化治(zhi)理(li)(li)方案。噪(zao)音(yin)(yin)治(zhi)理(li)(li)是(shi)一(yi)項長期而艱巨的任務,需要全社會的共同努力。只有(you)(you)(you)每個人都積極(ji)參與和配合,才能夠實現對噪(zao)音(yin)(yin)污染的有(you)(you)(you)效(xiao)治(zhi)理(li)(li)。然后(hou),噪(zao)音(yin)(yin)治(zhi)理(li)(li)的成功不(bu)僅只是(shi)為了改善居民的生活(huo)環境(jing),更是(shi)為了營(ying)造一(yi)個健(jian)康、舒(shu)適、安(an)靜的城(cheng)市,為人們創造更好的生活(huo)質量。武漢雄派(pai)環保工(gong)程有(you)(you)(you)限公司專注于噪(zao)音(yin)(yin)治(zhi)理(li)(li)。設備噪(zao)音(yin)(yin)治(zhi)理(li)(li)請(qing)找武漢雄派(pai)環保工(gong)程有(you)(you)(you)限公司,歡迎來(lai)電溝(gou)通(tong)。江(jiang)西(xi)噪(zao)音(yin)(yin)治(zhi)理(li)(li)
在室(shi)外,聲(sheng)(sheng)(sheng)(sheng)(sheng)音(yin)(yin)將(jiang)不斷(duan)傳(chuan)播開去。隨著傳(chuan)播距(ju)離(li)(li)(li)的增(zeng)加(jia),由于能量分(fen)散開來(lai),聲(sheng)(sheng)(sheng)(sheng)(sheng)壓級不斷(duan)下(xia)降(jiang)(jiang),理(li)論上,對(dui)于點聲(sheng)(sheng)(sheng)(sheng)(sheng)源(yuan),離(li)(li)(li)聲(sheng)(sheng)(sheng)(sheng)(sheng)源(yuan)距(ju)離(li)(li)(li)增(zeng)加(jia)每兩(liang)倍,噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)下(xia)降(jiang)(jiang)6dB。若某機(ji)(ji)器設備1米(mi)處的噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)為(wei)100dB,那么距(ju)離(li)(li)(li)它(ta)100米(mi)遠(相(xiang)當于距(ju)離(li)(li)(li)增(zeng)加(jia)約(yue)(yue)7個兩(liang)倍),那么噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)將(jiang)下(xia)降(jiang)(jiang)40dB,降(jiang)(jiang)低到60dB;距(ju)離(li)(li)(li)它(ta)1公里遠(相(xiang)當于距(ju)離(li)(li)(li)增(zeng)加(jia)約(yue)(yue)10個兩(liang)倍),噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)將(jiang)下(xia)降(jiang)(jiang)60dB,變(bian)為(wei)約(yue)(yue)40dB。另一方(fang)面,大氣對(dui)聲(sheng)(sheng)(sheng)(sheng)(sheng)音(yin)(yin)也(ye)有吸收作(zuo)用,尤其對(dui)超過2000Hz的高頻(pin)聲(sheng)(sheng)(sheng)(sheng)(sheng)音(yin)(yin),吸收效應(ying)更(geng)加(jia)明(ming)顯,使噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)隨與聲(sheng)(sheng)(sheng)(sheng)(sheng)源(yuan)距(ju)離(li)(li)(li)的增(zeng)加(jia)衰(shuai)(shuai)減量變(bian)得更(geng)大。實驗(yan)表明(ming),常溫(wen)常濕常壓下(xia),100m距(ju)離(li)(li)(li)對(dui)125Hz、500Hz、2000Hz的聲(sheng)(sheng)(sheng)(sheng)(sheng)音(yin)(yin)衰(shuai)(shuai)減量分(fen)別為(wei)0.05dB、0.27dB、2.8dB。雷(lei)電產生時(shi)的聲(sheng)(sheng)(sheng)(sheng)(sheng)音(yin)(yin)是(shi)含(han)有大量高頻(pin)成分(fen)的霹靂聲(sheng)(sheng)(sheng)(sheng)(sheng),由于距(ju)離(li)(li)(li)很遠,大多高頻(pin)成分(fen)被大氣吸收了,因此傳(chuan)到我們(men)耳朵里往(wang)往(wang)是(shi)隆隆的低頻(pin)聲(sheng)(sheng)(sheng)(sheng)(sheng)。西(xi)安(an)球磨機(ji)(ji)噪(zao)音(yin)(yin)治(zhi)理(li)哪家好電梯噪(zao)音(yin)(yin)治(zhi)理(li)請找武漢雄派環保(bao)工程有限公司。
變壓器噪聲(sheng)(sheng)共有(you)三(san)個聲(sheng)(sheng)源,一是(shi)鐵(tie)心(xin)(xin),二是(shi)繞(rao)組(zu),三(san)是(shi)冷(leng)卻器,即(ji)空(kong)載、負載和冷(leng)卻系統引起的(de)(de)(de)噪聲(sheng)(sheng)之和。鐵(tie)心(xin)(xin)產(chan)生(sheng)(sheng)噪聲(sheng)(sheng)的(de)(de)(de)原因是(shi)構(gou)成鐵(tie)心(xin)(xin)的(de)(de)(de)硅鋼片(pian)在(zai)交變磁場的(de)(de)(de)作(zuo)用下,會發(fa)生(sheng)(sheng)微小的(de)(de)(de)變化即(ji)磁致伸(shen)縮,磁致伸(shen)縮使鐵(tie)心(xin)(xin)隨勵(li)磁頻率(lv)的(de)(de)(de)變化做周(zhou)期性振(zhen)動。繞(rao)組(zu)產(chan)生(sheng)(sheng)振(zhen)動的(de)(de)(de)原因是(shi)電(dian)(dian)流(liu)在(zai)繞(rao)組(zu)中產(chan)生(sheng)(sheng)電(dian)(dian)磁力,漏磁場也能(neng)使結構(gou)件(jian)產(chan)生(sheng)(sheng)振(zhen)動。電(dian)(dian)磁力(和振(zhen)動幅值(zhi))與電(dian)(dian)流(liu)的(de)(de)(de)平(ping)方成正比(bi),而發(fa)射(she)的(de)(de)(de)聲(sheng)(sheng)功(gong)率(lv)與振(zhen)動幅值(zhi)的(de)(de)(de)平(ping)方成正比(bi)。因此(ci),發(fa)射(she)的(de)(de)(de)聲(sheng)(sheng)功(gong)率(lv)與負載電(dian)(dian)流(liu)有(you)很明顯的(de)(de)(de)關系。
