摘　　要：目的研究面向听力补偿应用的新一代多媒体无线音频系统。方法基于全数字2．4GHz开放平台，采用高品质的专业音频组件，将宽频高保真声音传入助听器和人工耳蜗中；另外，集成媒体播放器和存储器，内置专业语言教学软件，并且增加实时动态记录功能。结果新一代多媒体无线音频系统能够将频宽做到12kHz，接近CD音质的采样率，弥补了传统无线调频系统只保证7kHz以内的采样率（被称之为“收音机音质”）的不足；信噪比从40dB提高到65dB，并增加了教学及娱乐功能。结论新一代多媒体无线音频系统突破性地应用多项技术组合，有效地将高品质的音频信号传输给助听器和人工耳蜗的使用者，并为他们提供了更好的学习条件和多样化的生活、娱乐工具，显示出新技术在听力补偿中的重要作用。Objective To study the new generation of wireless multimedia audio system. Methods Based on digital 2.4 GHz platform,this system inputs the Hi-Fi sound of wide frequency band into hearing aids and cochlear implants by applying the professional audio groupware. Additionally, it integrates the broadcaster with memorizer, and also includes speech training software and real-time dynamic recorder. Results The new generation of wireless multimedia audio system can reach the frequency of 12 kHz, close to the effect of Compact Disc, and overcome the weakness of conventional wireless FM system, which can only ensure the frequency band within 7 kHz. Not only does the system improve the signal/noise ratio to 70 dB from 50 dB, but also adds some educational and entertainment functions. Conclusion The new generation of wireless multimedia audio system plays a very important role in auditory compensation, because it can not only effectively input high-quality audio signals to hearing aid and cochlear implant users, but also provide better learning conditions and diversified entertainment approaches by creatively combining several techniques.
