Abstract
The noise level for working arc furnace has been measured. Arc furnaces were found to be the source of infrasounds and acoustic field. The sound pressure levels for infrasounds range from 55 to 77 dB. It has been showed that particular noise level includes the onethird-octave band with middle frequency 100 Hz. The sound pressure levels in this band range from 105 to 110 dB.
摘要
已对电弧炉工作时的噪声水平进行了测量。发现电弧炉是次声和声场的来源。次声的声压级范围为55至77分贝。结果表明，特定的噪声水平包括中心频率为100赫兹的1/3倍频程带。该频带内的声压级范围为105至110分贝。
