摘要
根据耳鸣患者的辨声特征,结合掩蔽音治疗耳鸣的声学原理,完成了耳鸣治疗仪的系统设计与实现。该系统利用SPCE061A芯片具有的语音播放的硬件条件,并结合软件算法上的语音压缩函数库,实现了声信号的智能化输出。以凌阳公司的SPR4096作为外扩存储器,可实现大量语音资源的播放。临床试验结果表明该系统输出的语音信号精度高,具有良好的治疗效果。
Based on the sound distinguishing characteristics of the tinnitus patients, an instrument of tinnitus treating which is combined with the acoustical theory is designed. The hardware capacity for speech in SPCE061A is used and the function of speech compression is embedded in software. Using the SPR4096 of SUNPLUS as an extent ROM, a large mount of data can be transformed to voice. The clinical test indicates the output signal is precise and can cure the tinnitus effectively.
