摘要

本研究為探討教室噪音防制措施實施前後，教室環境條件之變化情形及對學生學習相關因素之影響。立意選取台北市某國小為研究對象。以現場實測和問卷調查獲得實驗教室噪音、空氣品質之測值，及學生問卷之資料加以分析。結果發現教室噪音防制措施實施後，關窗之噪音衰減量達18.8dB(A)以上，較未實施防音措施前之衰減量（11.7dB(A)）為高。而室內CO2濃度分佈在教室噪音防制措施實施之後，為250～648ppm，較控制前之225～520ppm為高。防音措施實施後，學生感覺關窗後覺得「悶熱」的比率為48.8%，「流汗」的比率則增加至52.0%，與防音前比較達顯著差異。

The main purposes of this study were to explore the effects of the noise control strategies on schools' noise and indoor air quality, and the subjective physical and psychological influences students. The purposive sampling method was adopted selecting the subjects from Lung-An Primary School in Taipei. The data were collected by field measurements and questionnaires. Results indicated that after the classroom's noise control strategies were fulfilled, by closing windows, the noise reduction exceeded 20dB; and the average noise attenuation was also improved from the original 11.7dB(A) to 18.8dB(A). After the classroom's noise control strategies were implemented, the indoor CO2 concentration was increased from the original 225-520ppm to 250-648 ppm. In the case of closing window, regarding the indoor air quality, 48.8% students' felt sultry, and as the physiology was involved, as high as 52% students' answers were sweating, those effects of which were noticeable.
