摘要:
目的 探讨陶瓷产业基地可能产生的噪声与削减措施, 减小其对人体健康的影响。 方法 基地建筑施工噪声测定方法, 主要依据建筑施工场界噪声测试方法实行;陶瓷生产过程噪声分别按工业生产室内、外噪声源预测模型进行测试计算;交通运输噪声以美国联邦公路管理局(FHWA)公路噪声预测模式计算得出其产生的噪声级别, 针对不同的噪声源采取相应措施。 结果 基地产生的噪声比较大, 如电钻声级达115 dB(A), 切割达126 dB(A), 大型货车达120 dB(A)。 结论 科学规划生产区, 对陶瓷生产车间进行合理布局, 提高工艺自动化水平, 强化建筑施工噪声管理及采取必要的隔噪降噪等措施, 可使环境噪声降低到较低水平。对建筑陶瓷产业基地噪声进行评估, 采取措施减噪, 有益于人体健康。 Abstract:Objective To reduce the health impact of noise generated from the ceramics industry base by investigating the noise levels and noise reduction measures. Methods The noise levels generated from the construction sites of the base were measured in compliance with Measurement Method for Noise from Construction Site. Estimates of ceramics' production noise were calculated using the prediction models of indoor and outdoor industrial noise sources. Estimates of traffic noise used the highway traffic noise prediction models by United States Federal Highway Administration(FHWA). Source-specified noise reduction measures were followed according to the estimated noise levels. Results The noise levels in the base were considerably high, e.g. 115 dB(A)by electric drills, 126 dB(A)by cutting, and 120 dB(A)by large trucks. Conclusion Noise can be lowered through scientific and rational layout of ceramic production areas, improved automation level, strengthened management of construction noise, and other necessary noise isolation and noise reduction measures. Noise assessments for the construction ceramics industry base, in combination with the subsequent corresponding measures taken to reduce noise, are beneficial to human health.
