摘要: 
由於工業化而帶來生活水準提高,民眾逐漸體認到環境保護的重要性,而對環境品質的追求亦日益殷切,企盼有一安寧的生活環境,致噪音陳情案件有逐年升高之趨勢,依據環保署統計數據,自民國77年統計至99年,陳情案件總計 634,328件,其中99年噪音陳情案件總計64,476件,較98年60,768件增加3,708件。就音源別分析,以營建工程占 31.3% (20,181件),娛樂及營業場所占 29.1 % (18,726件)最多,其次為其他占15% (9530件)。由於台灣地狹人稠,土地使用分區未臻完善,故常見工業區及住宅區混雜之情形。因此如工廠未有良好之噪音防護設備,將可能直接或間接影響民眾生活,而使得工廠噪音陳情抗爭時有所聞。
本研究以新竹工業區附近,屢遭民眾陳情噪音過大的電子廠為案例,分析其噪音來源以並探討其改善措施之成效。經以精密噪音計量測1/3八音度頻帶頻譜,發現該廠之噪音源主要來自空調冷卻水塔及洗滌塔,屬於中頻音,其單獨運轉時之噪音值分別約77.9 dB(A)及75.7dB(A)。初期噪音改善工程,係針對所有冷卻水塔風扇馬達安裝變頻控制器,以降低風扇馬達噪音之產生。然而由於冷卻水塔風扇馬達常需全載運轉,導致改善效果有限。建議後續應以吸音材料搭配隔音牆(材)進行進階改善,採用多孔性三明治或剛性材三明治板當作隔音材應較可符合其需求。此外,若工廠處於建廠規劃階段,應預作噪音防制整體規劃,可避免日後遭遇噪音改善問題之困擾。

With increasing life standards brought by industrialization, people realize the importance of environmental protection gradually. They are more eager to pursue the environment quality and expect a peaceful living environment, which results in the increase trend of noise petition cases year by year. According to statistical data of Environmental Protection Administration, from 1988 to 2010, total petition cases are 634,328, in which noise petition cases are 64,476 in 2010, increasing by 3,708 compared with 60,768 in 2009. From the noise source aspect, construction projects account for 31.3%(20,181), entertainment and business sites account for 29.1 %(18,726), and followed by others accounting for 15%(9530). It is common that industry district and residential district are mixed because Taiwan is narrow and crowded and land use zoning is inadequate. Therefore, if there is no good noise protection equipment in the factories, people''s life may be affected directly or indirectly and noise petition cases can happen sometimes.
Taking the electronics factory, located near Hsinchu Industrial Park and complained by the residents many times due to noise, as case, this study identifies the noise source and discusses the effect of improvement measures. A precision noise measurement meter is used to record the one-third octave band spectra. Results show that the main noise source of residential district is from air conditioning cooling tower and scrubber, which is intermediate frequency sound. When running independently, the noise levels detected aside the equipment are about 77.9dB(A) and 75.7dB(A) respectively. Preliminary improvement to noise has been carried out and it improves the situation by installing variable frequency controller on fan motors of all the cooling towers to lower the noise. However, the effect is limited because cooling tower has to run with full capacity usually. It is suggested that acoustic absorptive materials and soundproof walls (material) should be used for subsequent improvements and porous sandwich boards or rigid sandwich board should be used as soundproof material, which can meet the requirements. What''s more, if the plant is under planning, it is suggested that overall noise control program should be made so as to avoid the troubles caused by the noise improvements in the future.
