摘要
针对低气压但无明显高原反正症状的海拔高度范围内的不同声环境进行实验研究。有24名在校大学生参与了实验,分别记录他们在低气压下对不同声环境的主观评价指标——声感觉评价以及客观评价指标——心率的变化情况。通过对受试者的声感觉评价值及心率变化的统计分析,认为受试者总体随压力降低以及噪声水平的提高,声感觉评价值升高,同时平均心率上升;但不同声环境下个体反应并不一致,且男性和女性声感觉评价值的变化情况也不一致。
The purpose was to study acoustical environment under low-pressure and asymptomatic altitude reaction. Twenty-four undergraduate students participated in the experiment,in which their subjective evaluation indexacoustic sensory evaluation values and objective evaluation index-charge of heart rate were recorded respectively under low-pressure of different acoustic environment. Through statistical analysis of the subjects of acoustic sensory evaluation and charge of heart rate,it thought that acoustic sensory evaluation values of the subjects＇ increased,along with the pressure reduction and noise improvement,while the average heart rate rose. But the individual response was different under different acoustic environments. And the charge of the male and female＇s acoustic sensory evaluation values were also inconsistent.
