In order to better judge the degree of hearing loss and the fitting of hearing aids, hearing detection equipment is required.
  • Hearing test equipment is a routine device for hearing tests and is widely used in medical clinics. Hearing detection equipment is different from other tests. In order to ensure accurate and reliable hearing detection results, in addition to strict requirements on testing equipment, there are special requirements for the environment in which hearing detection is performed, especially environmental noise. Environmental noise exceeding a certain limit will be It has a bad influence on the test results. Only when the environmental noise meets certain requirements can the accuracy and reliability of the test results be guaranteed.

Description

听力诊疗装置
技术领域
本发明涉及听力诊疗的领域, 特别是涉及一种具有基于全数字音频音调信 号合成发生器模块的听力诊疗装置。 背景技术
听力测试是通过外加声音刺激听觉来判断其功能是否正常的技术方法, 它 可以用于诊断和鉴别听力障碍或听力受损。 为了更好的进行听力损失程度的判 断以及助听器的验配, 需要借助听力检测设备。
听力检测设备是听力测试的常规设备, 在医学临床中得到广泛的应用。 听 觉检测设备不同于其它测试, 为了保证听力检测结果的准确可靠, 除了对检测 设备有严格的要求以外, 对听力检测所在的环境也有特殊的要求, 特别是环境 噪声, 超过一定限度的环境噪声会对检测结果造成不良影响, 只有环境噪声满 足一定要求, 才可以保障检测结果的准确性和可靠性。 同时, 听力测试过程复 杂, 一般临床上采用模拟客观测试的方法, 但是也存在数据转换过程烦琐, 准 确度难以保证的缺点。 听力检测包括客观听力检测 (比如, 声阻抗 0AE检测、 脑干诱发电位 ABR检测、多频稳态诱发电位 ASSR检测),和\或主观听力检测(比 如, 纯音听力测试)。 这些原理不同、 性能各异的听力检测设备相互独立、 互不 相连, 采用自带外加单音调刺激声源。 但采用这些由单音调声信号剌激而测得 的听力水平是否能代表听觉神经对现实生活中各种复合声信号的感知水平, 一 直备受质疑。 特别是对聋儿, 听得见并不表示听得清听得懂, 用某些儿童喜欢 听的复合音调或言语比单音调枯燥的声音更能刺激其听觉神经 (比如儿童天生 对某些动物叫声、 音乐、 妈妈爸爸等言语词汇非常明感), 从而更能准确反映其 听觉感知水平, 更有效地指导验配调试助听器, 优化助听器的听力康复辅助功 效。 因此, 非常必要将各种听力检测设备的听力检测结果进行综合评估, 将检 测所需的剌激声从单音调扩大到复合音调, 甚至模拟动物叫声和人的言语。
耳鸣是在没有外在环境声音条件下患者感觉到耳内或头颅内有某种或多种 声音的听力障碍, 大部分的主观性耳鸣尚无有效的治疗, 各种药物、 掩蔽、 习 服、 针灸、 电 /磁剌激、 超声、 高压氧、 催眠、 瑜伽、 心理疗法份均对某些耳鸣 患者具有一定的效果, 其中掩蔽疗法和习服疗法是一种生理性的声治疗方法, 需要使用专用的耳鸣治疗设备, 简便、 安全、 无明显副作用, 是治疗耳鸣的常 用方法。
目前, 掩蔽疗法, 通常是指让患者定期聆听一种与耳鸣声音频率接近的窄 带噪声, 让噪声去掩蔽患者自身的耳鸣声的方法; 习服疗法, 通常是指让患者 长期聆听一些缓和的宽频自然声, 让患者逐渐习惯并适应耳鸣声的方法。
目前, 市面上专用的耳鸣治疗设备, 其播放的噪声频率和响度都是事先由 医生通过专用的仪器为患者设置好的, 而患者耳鸣的主频率和\或响度和\音调 和\旋律可能不定期的发生变化, 这些耳鸣治疗设备无法产生从简单的纯音、 噪 声、 到复杂的复合声、 模拟动物叫声、 模拟人语言等从单声调到复合声调的声 音数字信号, 更不能随意调节频率、 响度、 音调、 旋律、 节奏, 不能为患者提 供个性化、 有针对性的耳鸣掩蔽或耳鸣习服治疗配方, 使得耳鸣治疗效果大打 折扣。 市面上专用的耳鸣治疗设备不能产生可以满足医学临床诊断所需的千变 万化耳鸣声音,
上述中, 在进行听力测试时需要使用听力检测设备, 而耳鸣诊疗时需要使 用专用的耳鸣治疗设备, 分体式设备繁琐复杂, 同时也增加了相应的成本, 此 外, 在助听器验配过程中, 以及其他听力测试和听力治疗过程中, 都会涉及到 需要发出各种声音并且记录和存储。
