Abstract

Acoustic measures of construction site noise are important for hearing loss prevention and safety. This work examines noise exposure assessment using binaural measurements to pave the way for more accurate noise characterization and hearing loss prevention in loud workplaces. Recordings were made over three days on a construction site, and noise exposure was estimated using state-of-the-art methods (a shoulder-worn dosimeter) and binaural measurements (microphones at each ear). For the binaural assessment, noise exposure was quantified at each ear to identify the higher- and lower-exposure ears, and the assessment incorporated kurtosis, a statistical measure that quantifies impulsiveness of the noise. The impulsiveness of the noise of four construction tools was also assessed. For this set of measurements, traditional hearing loss risk assessment consistently underestimated the noise exposure relative to binaural assessment. Moreover, the binaural measurement method exposed multiple cases of asymmetric noise exposure that are not detectable using the traditional method. Overall, there are clear benefits to assessing risk using binaural measurements and more detailed analysis methods.

使用双耳测量和分析的建筑工地噪音暴露评估。
建筑工地噪声的声学措施对听力损失的预防和听力安全具有重要意义。本研究使用双耳测量方法检查噪声暴露评估,为更准确的噪声表征和在嘈杂的工作场所预防听力损失铺平道路。在一个建筑工地进行了三天的录音,并使用最先进的方法(肩戴剂量计)和双耳测量(每只耳朵上都有麦克风)来估计噪声暴露。在双耳评估中,对每只耳朵的噪声暴露进行量化,以识别高暴露和低暴露的耳朵,并将峰度纳入评估,这是一种量化噪声冲动的统计度量。并对四种施工工具的噪声冲动性进行了评价。对于这组测量,传统的听力损失风险评估相对于双耳评估始终低估了噪声暴露。此外,双耳测量方法暴露了多种使用传统方法无法检测到的非对称噪声暴露情况。总的来说,使用双耳测量和更详细的分析方法来评估风险有明显的好处。
