摘要

人類對於聲音的探索而言，過去而言已有很多研究進行探討噪音對人員的影響或在靜態環境下的聽覺績效，但卻極少有研究探討在動態環境下對人員聽覺偵測之實際評估，本研究係比較不同的動、靜環境，包括靜態(Static)模式、翻滾運動(Roll)及俯仰運動(Pitch)等三種；與改變環境噪音干擾（安靜、人聲干擾及低頻輪機聲等三種）下，探討人員的聽覺績效優劣情況及反應時間。
本研究的運動環境，係以六軸平台模擬艙產生頻率為為0.3赫茲、振幅為±8°（翻滾、俯仰）的低頻運動模式。環境噪音則人聲干擾音量為65分貝、低頻輪機聲音量則為75分貝。
本實驗採用3 × 3的設計方法，受測者共有24位，每組各8位，實驗自變數包含動態環境及噪音干擾環境，應變數為反應時間、正確率及性別。實驗結果顯示
實驗結果顯示，動態環境下的正確率明顯受到性別之影響（p=0.004），而環境噪音干擾亦明顯有產生影響（p=0.004）。本研究結果將可初步提供人員對於新人訓練環境之設計及選擇，以利整體績效及辨識之提昇。

For the exploration of sound, there has been a lot of research in the past to explore the effects of noise on people or in the static environment. However, few studies have explored the actual evaluation of auditory detection in the dynamic environment. This study is a relatively different dynamic and static environment, including the static (Static) model, Three kinds of roll motion (Roll) and pitching movement (Pitch), and three kinds of environmental noise interference (quiet, voice interference and low frequency turbine sound) were used to discuss the hearing performance and reaction time of the personnel.
he motion environment of this study is a low frequency motion mode with a frequency of 0.3 hertz and an amplitude of + 8 degrees (roll, pitching) in a six axis platform, while the ambient noise is 65 decibels, and the low frequency turbine is 75 decibels.
In this experiment, a 3 x 3 design method was used. There were 24 subjects in each group, each of which was 8. The experimental self variable included dynamic environment and noise interference environment. The number of strain was reaction time, correct rate and sex. The experimental results showed that the experimental results showed.
The results show that the accuracy of the dynamic environment is obviously influenced by the gender (p=0.004), and the environmental noise interference is also significantly affected (p=0.004). The results of this study will provide a preliminary design and selection of the personnel for the new training environment, in order to improve the overall performance and identification.
