5128-C 型 - 高频头和躯干模拟器

高频头和躯干模拟器 (HATS) Type 5128 系列内置逼真的耳朵和口腔模拟器，逼真地再现了普通成人头和躯干的声学特性。高频HATS专为原位电声测试而设计，可以覆盖整个可听频率范围(高达20kHz ) 。

 

核心高频帽5128-C型有几种变体，没有耳朵或嘴，适用于更简单的应用。

 

5128型符合ITU-T建议。P.58、IEC 60318-7和ANSI S3.36-1985

5128型和4620型耳模拟器已被ITU-T批准为符合P.57(耳模拟器标准)和P.58(HATS标准)要求的标准化解决方案，这意味着它们现在可用于移动电话等通信设备的法定批准，以用于移动电话网络。

4620型耳模拟器是4.3型新标准耳模拟器的基础，它独特地允许精确到20kHz的人耳阻抗加载。

4.3型耳道模拟器的另一个显著特征是标准中定义和规定了完整的平均耳道几何形状。这样可以更好地评估插入耳朵的产品的物理形状，如耳塞和助听器。

 

4620 型的设计是对以前的 3.3 型耳模拟器的全面修订，其基础是涉及多个人体受试者的广泛研究，以及相关的耳道几何形状和声阻抗测量。结果是对整个频率范围内的平均人类响应进行修正，而不仅仅是之前未定义的高于8kHz的高频区。

结果是对人类所感知的音频性能的评估更加真实。

可从ITU-T网站下载有关新标准的全部信息。

 

使用场景

Ul.
  • 根据国家和国际通信质量标准测试智能手机音频性能。这包括测试移动和无线 ；手机
  • 评估耳机双向通信在存在背景噪声和可能产生反馈进入系统的条件下的可理解性
  • 使用会议电话和智能扬声器等免提设备进行双向通信时语音可懂度评估，基于人类语音的准确生成，用于评估方向性、可懂度、反馈和背景噪声抑制
  • 便于评估水平、方向性和嘶哑性发生变化的人类语音的麦克风风录音准确性
  • 完全按照人类感知质量的方式测量耳机的音频响应。这使设计人员能够识别并纠正耳机设计中导致频率响应出现伪影的异常现象。新的耳道设计为耳内耳机的设计人员提供了最大的好处，其中几何配合对评估至关重要
  • 具有正确解剖定位的助听器音质评估
  • 使用正确的耳道几何形状和头部解剖结构测量听力保护器的衰减和有效密封
