下面结合附图对本发明的较佳实施例进行详细阐述， 以使本发明的优点和 特征能更易于被本领域技术人员理解， 从而对本发明的保护范围做出更为清楚 明确的界定。 请参阅图 1和图 2所示， 本发明实施例包括： 一种耳鸣诊断测试装置， 包括： 左耳全数字音频音调信号合成发生器 101、 右耳全数字音频音调信号合成发生器 102和操控模块 20。 所述全数字音频音调信号合成发生器， 产生耳鸣诊断测试所需的音频信号； 所述音频信号包括纯音、 噪声、 复合声等。 左耳右耳每只耳朵都配置一个全数 字音频信号合成发生器， 在宽频范围 （比如 30KHz ) 内可调声压级范围 OdB - 120dB。 所述全数字音频音调信号合成发生器可以产生純音和 \或噪声和\或复合 声和\或模拟动物叫声和\或模拟人语言等从单音调到复合音调的声音数字信号， 并可以随意调节频率和\或响度和\或音调和\或旋律和\或节奏。 如图 2所示， 所述全数字音频音调信号合成发生器包括纯音信号发生模块 11、 噪音信号发生模块 12、 复合声信号发生模块 13、 录音信号发生模块 14、 音 频信号标定校准模块 15和音频信号输出模块 16。 所述纯音信号发生模块 11， 产生纯音音频信号， 纯音是单一频率和强度的 音频信号， 可以为单一连续或间断音频信号 所述噪音信号发生模块 12， 产生噪声音频信号， 噪声是不同频率不同强度 无规则组合在一起的音频信号， 可以为单一连续或间断音频信号。 噪声包括白 噪声以及通过滤波器变换的有色噪声及频带宽窄可调节的噪声。 所述复合声信号发生模块 13 , 按特定合成规则产生复合声音频音调信号。 所述复合声信号发生模块包括： 多声道合成模块 131、预设信号波形模块 132和 耳鸣信号库模块 133。 复合声的形成主要有三种方式： 第一种为多声道合成： 包括一个或多个独立的单声道信号发生器 1311。 利 用数字音乐 /电子合成乐器国际标准 "电子乐器数字化接口 MIDI"规格所产生的 128个标准音色和 81个打击乐器排列， 将逻辑算法和参数变为数字信号输入数 字信号处理器 DSP或经过 PC中央处理器 CPU处理来发声， 每个单声道信号发 生器可以在任何设定频率和声压级范围内发声， 比如 10Hz - 30KHz, OdB - 120dB。 将多个（比如两个及两个以上单声道信号发生器）独立的音频信号按照 预设的复合方式进行定性定位定量的混合与合成， 就像交响乐团根据乐谱演奏 交响乐一样， 生成所需的音调、 旋律、 节奏、 响度的复合声音。 每个声道就像 一个单一乐器， 其音频信号变量包括频率和响度。 各个声道在复合声音中的贡 献度主要由其排列方式和在给定频率下的响度决定。 复合声音频音调信号的音 调、 旋律、 节奏、 响度由多个单声道信号发生器的排列方式和各个单声道信号 发生器的贡献度决定。 复合声音的总响度还可单独调节。 第二种为预设信号波形： 根据预设音频信号波形， 调节波形坡度、 波形幅 度、 波形峰值延长、 波形周期、 波形持续时间等参数。 波形横坐标表示时间， 纵坐标代表声音响度。 常设波形包括直线波、 沖击波、 斜坡波、 锯齿波、 三角 函数（正弦、 余弦、 正切、 余切） 波、 梯形波、 矩形波、 脉冲波、 白噪声、 有 色噪声等。 第三种为耳鸣声信号库： 将临床医学验证后收集的各类耳鸣声的数字信号 进行编排分类存储和调取， 根据耳鸣患者个性化测试， 通过微调所调取的参考 耳鸣声信号的参数包括但不限于频率和响度， 还原并输出符合患者个性化需求 的耳鸣声音信号。 所述耳鸣声信号库， 耳呜诊断技术人员可以将临床耳鸣诊断 所有患者的诊断结果储存到所述耳鸣信号库中， 便于今后调用参考或作医疗分 类统计分析。 所述录音信号发生模块 14， 产生录制的音频信号。 录制信号： 根据输入或 录制的音频音调信号， 通过调节相应参数包括但不限于频率和响度， 输出符合 患者个性化需求的合成声音信号。 ~~所述音频信号标定校准模块 15， 通过内置或外置听力分析仪， 对包括专门 配置的扬声器耳机在内的整个音频软硬件系统， 在给定频率下做声压级或声强 实验标定校准。 所述音频信号标定校准模块 15可以在任何设定频率和声压级范 围内， 比如 10Hz - 30KHz， 0dB - 120dB, 进行手动或自动声压级或声强实验标 定校准。 扬声器耳机放置于模拟人耳的声腔内进行气导实验标定。 所述音频信号输出模块 16， 将调节好的音频音调信号输出。 所述操控模块， 对所述全数字音频音调信号合成发生器进行操控。 可以现 场操控， 也可以远程操控。 当耳鸣患者不能到现场、 或间隙式耳鸣患者在检测时不能出现耳鸣时， 可 以根据对耳鸣的描述， 设计出多个可能与患者耳鸣类似的耳鸣治疗音频音调处 方， 分别下载到耳鸣治疗疗仪， 让患者回家， 出现耳鸣时再佩戴， 自己调试体 验预设的几种处方， 找出与自己耳鸣相似的一个或几个处方， 再反馈回耳呜诊 治专家， 帮助缩小试验范围， 迅速确诊耳鸣。 耳鸣治疗仪分两大类： 没有听力 补偿功能的耳鸣治疗仪、 有听力补偿功能的耳鸣治疗仪。 远程调试耳鸣信号， 通过手机开放平台传输信号。 在耳鸣治疗仪上装无线 发射模块 GPRS。 直接实现机-机对话和传输信号。 耳鸣诊断可以单耳或双耳同时交互进行； 双耳同时交互诊断对多数耳鸣患 者效果更好， 可以优化和稳定还原双耳耳鸣。 左右耳可以互相复制后再作个性 化调试，左耳右耳的数字音频信号合成发生器可以同时播放和调试交叉进行。 耳鸣诊断输出的耳鸣治疗处方主要包括耳鸣掩蔽和耳鸣习服两种物理方 法， 其原理主要是通过对神经系统重新训练或再编码， 降低中枢兴奋性， 增加 中枢抑制， 切断耳鸣与不良情绪的恶性循环， 促使患者对耳鸣的适应， 不感知 或降低感知耳呜， 从而达到治疗的目的。 耳鸣治疗处方的音频音调信号包括纯 音、 脉沖纯音、 混合纯音、 混合脉冲纯音； 白噪声、 有色噪声、 宽窄带噪声； 单一啭音、 多种混合啭音、 脉沖啭音； 录制音频信号； 预设多种耳呜声音和自 然声音模块； 弗德曼（Fredman )掩蔽曲线、 掩蔽听力图、 掩蔽阔上下限等信号 数据分析、 掩蔽和习服治疗处方确认和输出。 耳鸣治疗处方是耳鸣声信号的定 位或音频音调数字表达， 含复合参数（包括音调、 节奏、 旋律等）和基本参数 (包括中心频率、 频宽、 响度等）， 可以保存为 pdf图片文档格式的音频信号图 供打印或存档； 也可以通过编码器将时域波形信号转换为频域信号， 直接输出 频 域 音 频 非 压 缩 格 式 或 压 缩 格 式 ， 比 如 .wav, .mp3, .mp4， .mp5, .cad, .ram, .wma, .mid等，下载到基于音频信号播放器 的耳鸣治疗仪， 经解码后供患者佩说戴收听； 还可以直接无缝输入助听器验配模 块， 通过编程调试， 为患有耳鸣的听障患者个性化验配兼具听力补偿和耳鸣治 疗的助听器。 书
以上所述仅为本发明的实施例， 并非因此限制本发明的专利范围， 凡是利 用本发明说明书及附图内容所作的等效结构或等效流程变换， 或直接或间接运 用在其他相关的技术领域， 均同理包括在本发明的专利,保护范围内。
