住宅室內生活噪音源及居民反應之調查

Investigation of Interior Noise Sources and Responses of Residents in Houses

本研究主要調查住宅室內噪音發生源之種類及其頻率特性，調查三十種室內生活噪音，並藉由問卷方式調查民眾對室內噪音之反應，透過現場量測、錄音、放音、問卷調查等步驟，以統計方法分析室內噪音源對居民生活之干擾程度、刺耳程度及辦別程度。本研究結論：(1)提出民眾對室內生活噪音之受干擾程度，結果顯示所有年齡層從會影響至非常干擾之比例合均超過70%以上，因此室內生活噪音對於民眾之干擾嚴重。(2)提出民眾對室內生活噪音刺耳程度之分析結果，結果顯示三十種室內生活噪音源之刺耳感受，約有6個屬於低沉，約有4個屬於中庸，約有20個屬於尖銳，顯示室內生活噪音源對於民眾之感覺屬於尖銳感受者較多，各年齡層之差異分析並不明顯。(3)提出民眾對室內生活噪音辦別程度之分析，結果顯示正確之比例約40％，錯誤之比例亦高達37％。(4)室內生活噪音之頻譜特性，依低頻域、中頻域及高頻域加以分析，與刺耳程度問卷調查結果比較，相似之比例約77%。

This research investigates sources of interior noise and analyzes their frequency characteristics. Thirty noise sources are recorded in the field and responses of subjects are surveyed by questionnaires according to the following four steps: field measurements, recording sound, replay noise to residents and making questionnaires. Then we analyze annoying degrees, rasping degrees and noise recognition of thirty interior noise sources to residents by statistic method. The results show the sum of percentages from annoying to extreme annoying exceeds 70％ of subjects, it seriously influences the residents. We analyze rasping degrees of thirty noise sources and classify six bass sources, four middle sources and twenty rasping sources. Most subjects respond interior noises are rasping and there is no difference by ages. Besides there are 40％ of subjects could recognize the right noise sources and 37％ get the wrong answers. Finally we compare frequency characteristics to rasping degrees by three different frequency domains. The result shows there are about 77％ of noise sources have a good match.
