瑞士峰力听力集团最新推出的Spicy平台产品的一个关键技术，就是其市场领先的、独有的zoom 言语聚焦技术，旨在帮助提高听力损失人士在其听力康复过程中一个最难以解决的问题，即复杂环境下的言语理解能力问题。我们说，在安静环境下，助听器相对比较容易达到效果，而在嘈杂环境下，要让助听器达到比较好的聆听效果则比较困难。峰力公司的言语聚焦技术正是在这个领域的一个革命性的先进尝试，能帮助患者在嘈杂环境下用两只耳朵来聆听原来只能由一只耳朵来提高的方向性，而且，即使在不是面向说话者的嘈杂环境下，患者也照样能够着听取占主导地位的声音、提高聆听清晰度。
在这里我们提醒各位用户，峰力Spicy平台最新的zoom 言语聚焦技术对于儿童助听器用户来说特别有利。儿童经常处在嘈杂的、闹哄哄的环境，言语清晰度对他们来说特别重要。以往的任何产品，其方向性麦克风都仅仅只能聚焦前面的声音。而儿童往往处在复杂的环境中，主要的声音不但可能来自其前，也很可能来自由侧面和后面。这个功能-立体声以及自动方向性功能，对儿童提高嘈杂环境下听音能力的一个非常好的功能，可以让儿童在嘈杂环境下的不同方向传来的声音都能听得更清晰。

Interview with Nathan Schau, Au.D., Manager of Audiology, Phonak US
Topic: Phonak Zoom Technology
10/17/2011
Nathan Schau, Au.D.
SMAKA：这是卡罗琳, 来自听力学在线（AudiologyOnline），现在跟我谈话的是来自瑞士峰力听力集团的MATHAN SCHAU博士。博士，欢迎您来到听力学在线。
SCHAU: I抦the Manager of Audiology for Phonak U.S. My primary role entails managing clinical trials and developing evidence-based research for new hearing solutions. I also represent Phonak at different industry functions and write articles for hearing health care journals.
I抦an audiologist, and I dispensed hearing aids during my clinical career. Prior to becoming Manager of Audiology, I held other roles at Phonak including being an outside trainer, as well as in technical support.
SMAKA：感谢内特。现在我们来谈峰力的言语聚焦技术。有三种不同的言语聚焦功能，是吗？
SMAKA: Thanks Nate. I抦looking forward to getting into the Zoom technology. There are three different Zoom features, correct?
SCHAU：是的。在我们的Spicy平台的产品中，有三种主要的言语聚焦声音放大技术，即立体声聚焦、自动聚焦、与高效能聚焦三种技术。旨在提高即使是在不面向说话者，嘈杂聆听环境的信噪比。
我们可以首先来看一下立体声声音聚焦功能。立体声声音聚焦功能是Spicy平台的顶级产品中，拥有方向性麦可风的产品的一个手动程度中的功能，这些产品包括Ambra、美人鱼S 9,、及智通9。Ambra产品线包括耳背机和耳道机，智通是一款耳道授话式产品（迷你隐形的耳背机-厦门益耳注）。
SCHAU: Correct. There are three primary Zooms that we抮e focusing on in our Spice generation of products: StereoZoom, auto ZoomControl, and UltraZoom with SNR boost. Phonak抯Zoom features were designed to help improve signal to noise ratio and help in those situations when the listener isn't able to look at the speaker.
We can talk first about StereoZoom feature. StereoZoom is available as a manual program in the premium-level Spice platform (S) hearing aids that have directional microphones. These products include the Ambra, all of the Aud閛 S IX wireless configurations, and the Na韉a S IX. The Ambra line does include custom models and standard BTEs, while the Aud閛 is a receiver-in-the-ear line and the Na韉a is a BTE.
有了立体声聚焦，两个助听器都可以同时切换到一个有针对性的定向模式，并且马上，两个助听器可以共同听取同一个完整的音频信号，实现两个助听器之前的共享（达到立体声双声道的效果-厦门益耳注）。这是一个伟大的解决方案，针对于象嘈杂的餐厅、聚会等最具有挑战性的环境。
With StereoZoom, both hearing instruments switch into a focused directional mode and simultaneously the full audio signal is shared between aids. This is a great manual solution when in the most challenging of environments like a party or a noisy restaurant.
SMAKA：自动言语聚焦功能和峰力公司几年前发布的言语聚焦功能是否有联系呢？
SMAKA:Is auto ZoomControl related to the original ZoomControl that was released a few years back?
SCHAU：嗯，这取决于用户要如何放大。助听器提供给配戴者一系列的言语聚焦可选性，让用户可以根据他们的特定需求来掌控，用户可以自行决定到底要聚焦于哪个方位。实际上，他们可以集中聆听某一个讲话人的方向，而不必面对着他们。
SCHAU: Well, it depends on how the user wants to zoom. The hearing aids provide wearers a range of zoom capabilities, depending on their specific needs. They can actually focus in, directionally, on a speaker without even having to look at them.
峰力高效能言语聚焦是一种最先进的言语聚焦技术，是吗？
SMAKA:UltraZoom with SNR (signal-to-noise ratio) boost is the most advanced type of zoom, correct?
SCHAU：我想说，立体声言语聚焦功能StereoZoom是一项最先进的功能，因为它使用音频信号的无线交流。而高效能言语聚焦UltraZoom也是一个最先进的定向功能，但它不需要无线互同。是的，高效能言语聚焦UltraZoom的确是方向性麦克风的二代产品。 它是一种多通道的自适应定向系统，这意味着每个通道内的方向性，都根据其最大的噪音源而改变。
并且UltraZoom同时还结合着提高了的信噪比，当Ultra Zoom启动时，助听器还会自动降噪声。
SCHAU: I'd say that StereoZoom is the most advanced in terms of a feature that uses wireless streaming of the audio signal and UltraZoom with SNR boost is the most advanced directional feature that doesn't require wireless streaming. Yes, the UltraZoom with SNR boost is really the next generation of directional microphones. As you know Phonak has pioneered directionality for a long time. UltraZoom is a multichannel adaptive directional system, which means that directionality changes within each channel based on the loudest noise source in that channel.
