摘　　要：本文阐述了一款人耳听力评测软件的设计及实现过程。该软件主要由听力评测模块与评测管理模块组成,可在计算机上运行,并通过计算机产生评测信号、控制信号的强弱以及产生掩蔽,能够较准确地评估被评测者的听力状况,还可配合气导耳机或骨导耳机进行气导听阈或者骨导听阈的检测,得到听阈曲线,并能够通过产生不同频率的纯音评测受试者的听觉范围。此外,应用该软件还能够对耳鸣患者进行耳鸣的音调及响度匹配评测。实际评测结果表明,该系统实现了听力评测与评测结果的管理,具有较强的可行性与实用性。A software for hearing test and results management has been designed and introduced in this paper, which can been run on the PC machine. An accurate evaluation of hearing can be got by generating test signal, controlling signal strength and masking. The air conduction threshold or bone conduction threshold is detected by using AC earphone or BC earphone and the threshold audiogram is obtained at the same time. The auditory range is tested by generating pure tone with different frequency. The pitch and loudness of tinnitus are matched for patients with tinnitus. The test result proves that the scheme is feasible and practical.
