背景與目的：在運動場上，運動員及運動觀賞者常會利用聲音或噪音來恫嚇對手，使其產生動作上的干擾，造成運動表現的下降，然而運動場邊的環境噪音對於運動員的運動表現是否會有影響，特別是平衡能力，過去的研究並未有明確定論。因此，本研究目的是探討噪音及其音量大小的干擾對年輕成人平衡的影響。方法：以二十位健康無聽覺障礙之年輕男性參與此研究，參與者隨機分派下測試兩種不同情況下（開眼及閉眼）之三種噪音方式介入（安靜站立、65分貝白噪音、85分貝白噪音）後的足底壓力中心（center of pressure, COP）身體晃動面積、晃動路徑距離、前後徑晃動、與左右徑晃動的差異。結果：發現噪音音量大小並未對平衡能力產生影響，只有開眼與閉眼狀態會對平衡產生影響。結論：本研究的結論認為噪音音量大小對於年輕成人之單腳站立平衡能力未有明顯之影響，其他聽覺刺激的特徵，例如頻率和節奏，對不同平衡表現的影響則須進一步研究。

Background and Purpose: In sports field, athletes and audience often use sound or noise to intimidate opponents and interfere with opponents' performance. However, whether environmental noise on the sidelines will affect sports performance of athletes, particularly balance, remains unknown. Therefore, the purpose of this study was to explore the influence of auditory disturbance on balance in young active people. Methods: Twenty healthy young participants without hearing deficit were included in this study. Each participant performed single-legged standing in 2 different conditions (eyes close and eyes open) randomly with 65dB white noise or 85dB white noise. The body sway area, path length, anterior-posterior sway deviation, and medial-lateral sway deviation of center of pressure (COP) were used as balance parameters during single- legged stance. Results: No statistically significant difference was found between 65dB and 85dB noise conditions. We only found significantly decline the balance in eyes close condition compared to eyes open condition. Conclusions: The study did not find significant influence of the loudness of white noise on single-legged standing balance in the healthy young population. Influences of other characteristics of auditory stimuli, such as frequency and rhythm, on various balance performances need further studies.
