【摘要】：目的开发一种便携式自我听力监测系统,并进行了初步临床评估。方法采用ThinkPad笔记本电脑、Cre-ative声卡、ER3A插入式耳机以及自制音频转换器建立起便携式听力自我监测系统。开发配套系统软件并校准信号输出强度。系统建立后,首先通过小样本正常人预实验发现系统设计中存在的重大问题并进行调整。系统经过改进和调整后,在18例(36耳)听力正常人中进行纯音测听听阈与自测听阈的对比。每位受试者分别进行测听室内的纯音测听和软件自测。计算各频率阈值差值。结果获得了便携式自我听力监测系统的原型机。经过调整的系统自测结果与纯音测听结果总体吻合度较好,特别是250~4kHz偏差较小(各频率总体偏差值分别为-1.81±8.29、-1.81±7.09、0.56±6.95、3.33±5.35、1.94±6.68、3.47±5.71 dB)。但125、6k、8kHz偏差较大(125 Hz偏差值为-6.11±8.29 dB;6 k、8 kHz偏差值分别为-5.28±6.54、-3.33±6.87 dB)。环境噪声对测试结果有一定影响。结论便携式听力自我监测系统提供了一种便捷的自动测听方法,需进一步验证可靠性。
[Abstract]:Objective to develop a portable self-monitoring system for hearing, Methods A portable hearing self-monitoring system was established by using ThinkPad notebook computer / Cre-ative sound card ER3A plug in earphone and self-made audio converter. The matching system software was developed and the strong signal output was calibrated. After the establishment of the system, First of all, the major problems in the system design are found and adjusted through the pre-experiment of small sample normal people. After the system has been improved and adjusted, A comparison of pure tone audiometry and self-measured hearing threshold between 18 normal subjects and 36 ears of normal hearing was carried out. Each subject performed pure tone audiometry and software self-test in the audiometry room respectively. The difference of frequency threshold was calculated. The portable results were obtained. A prototype of a self-hearing monitoring system. The adjusted self-test results are in good agreement with the results of pure tone audiometry on the whole. In particular, the deviation of 250kHz is small (the total deviation values of each frequency are -1.81 卤8.29kHz -1.81 卤7.09ng 0.56 卤6.95U 3.33 卤5.35U 1.94 卤6.685kHz 3.47 卤5.71dB.Conclusion the deviation of 125kHz is -6.11 卤8.29 dB ~ 6kHz = -5.28 卤6.54 ~ 3.33 卤6.87 dB). The monitoring system provides a convenient automatic audiometry method. Reliability needs to be further verified.
