本研究之主要目的為探討實施教室防音措施前後,教室環境噪音及空氣品質之情形,與對教師和學生自覺性生理及心理方面之變化情形。本實驗研究立意選取臺北市龍安國小為研究對象,計有學生二百五十四名,教師八名。研究方法主要以現場實測和問卷調查獲得實驗教室環境噪音,空氣品質、以及教師與學生之資料,茲將就本研究結果摘要如下:一、教室防音措施實施之後,教室關窗時對於頻率500-4000Hz之衰減量最高,皆達20.0dB(A)以上;至於在音量衰減方面,平均衰減量為18.8dB(A),較未實施防音措施前之衰減量(11.7dB(A))為高。空氣品質亦符合日本學校環境衛生之基準。二、教室環境噪音對教師自覺性的生理性影響以「容易感到疲勞」和「感到聽力降低」為主,在自覺性心理影響上,以感到「煩躁不安」為最主要的 反應。在教室空氣品質方面,教室防音措施實施之後教師自覺性生理影響以「感到悶熱」為主要反應;在自覺性心理影響上以「煩躁不安」和「有壓力」為主。三、教室防音措施實施之後,整體上,學生覺得教室比較不吵,感覺不舒服的比率亦降低,達顯著差異;在空氣品質方面,學生回答關窗後感覺悶熱的比率為48.8%;在生理方面回答關窗後「流汗」的比率增加至52.0%,並達顯著差異。

The main purposes of this study were to explore the effects of the noisecontrol strategies on schools' noise and indoor air quality,and the subjectivephysical and psychological influences on teachers and students.The purposive samplingmethod was adopted in selecting the subjects of 254 students and 8 teachers fromLong-An Primary School in Taipei.The data were collected by field measurements andquestionaires. The following conclusions were drawn from the study.1.After the classroom's noise control strategies were fulfilled,by closing windows ,the noise reduction for the frequency of 500-4000 Hz exceeded 20dB ; and the the average noise attenuation was also improved from the original 11.7 dB(A) to 18.8 dB(A) .Indoor air quality reached the standards of the Japenese school's environmental health.2.As far as the school's noise was concerned, the physical influences on teachers were easily to feel fatique and the decrease of hearing ; as for the subjective psychological influence, their main reaction was feeling fidgety. Regarding the indoor air quality , after the school's noise control strategies were implemented , the physical influence on teachers was feeling fidgety and getting pressure.3.After the school's noise control strategies were implemented ,most of students felt that the classroom was less noisy and percentage of students felt uncomfotable was also lower statistical significantly. In the case of closing windows , 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.
