In order to investigate residence-commercial complex zoning sound environment from user`s point of view, there were 800 questionnaires handed round, and 273 questionnaires were replied. There are six evaluation factors in influencing molding commercial space sound environment. According to the users` observation and experience, three factors play important roles influencing users` evaluation regarding sound environment design, including amenity（pleasant, comfortable or unpleasant, uncomfortable）, vitality, and atmosphere of warmth. In the regression analysis, amenity and volume have a negative relationship（r=-0.558）, which means volume is an important factor in commercial space sound environment molding. In the past, high volume amplifier system was applied extensively in commercial district to attract more crowds. However, amenity is declined under such noisy environment. It is a very important issue to study the trade-off relationship between these two situations and improve noise problem in residence-commercial complex zoning.
为了从使用者观点实际了解住商混合使用之商业区其音环境之情形，本研究从台南市都会区中发出800份问卷进行调查，其中有273份问卷获得回收（回收率34.13%），其中使用者对商业空间音环境之塑造有六项主要评价因子，依照实际使用者对商业空间音环境设计之评价情形建构了三个轴向主要因子，分别为第一因子：快适感（愉快、舒适/不愉快、不舒适），第二因子：空间活力感，第三因子：温暖感，在回归分析中快适感与音量呈现负相关（r=-0.558），显示商业区中之音量可作为业空间音环境塑造具快适感之一项指标，商业空间不需大的音量亦可使空间具有快适感，此与过去需透过高分贝扩音器才能招揽客人的商业形态有所不同，若能放弃以分贝之扩音器为塑造商业空间良好音环境的方式，未来台湾住商混合中住宅部份的高噪音困扰应可改善，故适当地限制商业空间大音量的使用显得相当重要，亦可提升使用者对商业空间快适感。
