为了研究刺激频率耳声发射的原理、检测方式以及抑制调谐曲线的特性，以满足实验教学需求，研制了一套刺激频率耳声发射抑制调谐曲线的教学实验平台。该平台采用外置声卡作为信号采集系统，实时检测刺激频率耳声发射信号的阈值和抑制调谐曲线，进行结果显示，并可保存实验结果以备后续分析研究。该教学平台的搭建不仅为学生提供了掌握刺激频率耳声发射基础知识的必要实验条件，而且有利于培养学生的声学基本实验操作能力和发掘学生的创新性思维。

In order to study the principles, detection and analysis methods of the stimulus frequency otoacoustic emission(SFOAE)and the characteristics of suppression tuning curves(STCs),as well as to satisfy the requirements of experimental teaching, the teaching experiment platform for SFOAE STCs is developed. The proposed system is based on external sound card. Real-time processing is performed in the experimental platform to detect the threshold and suppression tuning curves of SFOAE, to show the results, and to save the data for future analysis. This teaching experiment system not only supplies the necessary experiment platform for students to understand the basic knowledge of SFOAE, but also helps students strengthen their operating ability and develop their creative thinking skills.
