目标
已经表明，低频噪声（LFN）（定义为具有低频（10-250 Hz）的主要内容的宽带噪声）可能对暴露的受试者是令人讨厌的。该研究的目的是比较LFN与宽带噪声（BBN）所造成的烦恼程度，没有占主导地位的低频分量在类似的A加权声压级。
材料和方法
研究对象为控制室的145名男性员工。他们通过耳机暴露在逐渐增加的dB A加权声压级范围内的62-84分贝的噪音。烦恼评级基于100分的图形量表。
结果
在可比的A加权声压级下，LFN被评为比BBN更烦人。任何噪音的烦恼评估不取决于年龄，就业时间或暴露于噪音在当前工作场所的水平。
结论
LFN比常规BBN对人类健康的影响风险更高，应在职业接触评估中予以考虑。
OBJECTIVES
It has been shown that low frequency noise (LFN), defined as broadband noise with dominant content of low frequencies (10-250 Hz), may be annoying to exposed subjects. The aim of the study was to compare the degree of annoyance caused by LFN with that caused by broadband noise (BBN) without dominant low frequency components at similar A-weighted sound pressure levels.
MATERIALS AND METHODS
Subjects included in the study were 145 male employees of the control rooms. They were exposed to noise through headphones at gradually increasing dB A-weighted sound pressure levels within the range of 62-84 dB. Annoyance rating was based on a 100-score graphical scale.
RESULTS
LFN was rated as significantly more annoying than BBN at the comparable A-weighted sound pressure levels. The annoyance assessment of either noise did not depend on age, length of employment or the level of exposure to noise at a current workplace.
CONCLUSIONS
LFN represents a higher risk of influencing human well-being than regular BBN and should be considered in the occupational exposure assessment.
