摘　　要： 由于许多火力发电厂锅炉安装了吹尘器 ,为了解它运行中的低频噪声和次声在工人工作场所的水平 ,我们对现场进行了测试。结果显示声音的主频在 6～ 1 0 0Hz左右 ,为次声和低频噪声共存 ,工作场所声压级在 80dB (A)左右。无论吹尘器是否运行均有次声存在 ,虽然运行时有些频段有所增加但不显著。 Dust removers have been installed for boilers in many thermal power plants.The sound pressure levels of low frequency noise and infrasonic sound at workplaces were measured.The results showed that the main frequencies were at about 6～100Hz and the sound pressure levels were about 80 dB(A).Infrasonic sound existed notwithstanding the dust remover was at work or not.Although sound levels at some frequencies increased when the dust remover was working,yet there was no significant difference.
