摘　　要：目的观察4名参试乘员在受控生态生保系统(Controlled Ecological Life Support System,CLESS)平台内工作和生活180 d的听觉生理学变化规律。方法通过测量CLESS系统中各个舱段的噪声声压级、分布状况和乘员个人噪声暴露剂量,评估噪声暴露水平。在舱内,利用便携式设备对乘员的听力水平变化进行动态跟踪分析,获得乘员听觉生理的变化规律和趋势,评估180 d持续密闭环境对乘员听力水平的影响。结果 180 d密闭环境条件下采用便携式设备测试听力,满足了长期航天密闭条件下的乘员听力监测需求;CLESS平台工作的噪声水平下,180 d内舱内乘员听力水平基本稳定,试验第5个月开始个别乘员单耳听力有3个以上频率段发生10 d B以上的下降。结论 180 d密闭环境噪声下,个别乘员听力水平在后期有下降趋势。Objective To observe the auditory changes of the four volunteers worked and lived in the Controlled Ecological Life Support System（ CLESS） platform for 180 d. Methods The level and distribution of noise in each module of CLESS and the individual noise exposure dose of the volunteers were utilized to assess the effect of noise exposure. The portable pad was used to dynamically record the changes of the hearing level of the volunteers in the experiment modules,and thus assess the effect on hearing level in a 180-day continuous noise exposure environment. Results The portable hearing test equipment could meet the needs of the hearing monitoring under long-term isolated conditions in the CLESS platform. The hearing level of volunteers during the experiment period was basically stable. But,starting from the 5 th month of the experiment,some individuals showed more than 10 d B decline in more than 3 kinds of frequency bands of monaural hearing. Conclusion In 180-day CELSS integration experiment,the environment noise made the hearing level decreased in some individuals of the volunteers during the later period.
