摘要: | 處於70分貝的環境下,人就會覺得心情煩躁,聲景直接影響了人們的健康與情緒。傳統都市公園設計上,只以視覺為首要主導,忽略了聽覺在人類經驗環境時的重要性,所以本研究期望探討遊客對於大安森林公園聲景的感覺。為理解都市公園聲景在不同地景中的脈絡,預先探討四種不同地景,再調查大安森林公園。利用問卷調查、錄音、噪音量測、GPS軌跡紀錄四種田野調查方法,以及描述統計和頻譜分析這兩種分析工具,統計聲景特性與偏好的關聯性。
量測聲景樣本的時間,至少須超過四十秒,聲景時序特徵才會趨於穩定。四個區域的近似模擬曲線中,唯有Beta值與時空有顯著相關。公園的近似模擬中,Beta、k值與時空顯著相關,未來研究的曲線精度仍需提高。人類活動、交通載具決定了聲景震盪程度與分貝值的大小。噪度、時段與遊客的好感度無關,與區域、聲音類別及聲音品質有關。在噪度無明顯改變的情況下,交通幹道的交會點好感度比較差。所以未來在設計都市公園上,應以改變區域地景特徵、聲音種類、聲音品質等方向努力,噪度不是關鍵。
In 70 decibel environment, human feel uncomfortable, sound directly affect people's health and emotions. Traditional urban park design, only visual as the leading, ignore the importance of human’s hearing experience in the environment, so this study is expected to explore the tourists of Daan Forest Park sound preferences. In order to understand the context of the city park in different landscapes, to explore four different landscape, and then investigate the Daan Forest Park. We use four kinds of field investigation methods, such as questionnaire survey, recording, noise measurement and GPS track, and the two analytical tools describing statistical and spectrum analysis are used to analyze the correlation between sound characteristics and preference.
The time of the sound sample, at least 40 seconds, the sound characteristics of the timing will tend to stabilize. In the approximate simulation curves of the four regions, only the Beta value is significantly correlated with the time and space. In the approximate simulation of the Daan park, the Beta and k values are significantly related to the time and space, and the curve accuracy of the future research needs to be improved. Human activities, traffic vehicles determine the degree of concussion of sound and decibel value. Noise, no correlation with time and tourist , but with the region, the sound category and sound quality. In the case of no significant change in noise, the traffic point of the intersection point of good impression is relatively poor. Therefore, the future design of the city park, should be to change the regional landscape characteristics, sound type, sound quality, noise is not the main factor. |
