大约5％的世界人口患有一定程度的听力损失，可以通过使用助听器来纠正。
令人震惊的是，该组中只有4％实际上会购买助听器，主要原因是该设备的成本以及相关的老年人负面耻辱感。
虽然这是一个解决刺激性问题的简单方法，但许多患者只有在绝对必要的情况下才能恢复佩戴助听器，这是安森美半导体通过无线技术进步的目标。
为了最大限度地减少佩戴助听器的视觉影响，安森美半导体数字信号处理（DSP）技术不断发展，以实现与包括智能手机在内的辅助设备的无线连接。
通过在智能手机上运行的应用程序来控制助听器对于这个行业来说是一个巨大的飞跃，并为助听器用户带来了巨大的变化。
除了更加离散之外，此功能还允许用户更轻松，更直接地控制其助听器设备。
例如，现在可以在智能手机上清楚地显示助听器上正在使用的收听程序（正常，嘈杂情况，音乐，电话等）。
用户甚至可以直接在智能手机上调整一些收听参数。
此外，可以轻松地向用户提供监控设备的性能，如电池电量，估计的剩余运行时间等。
其他优势利用了大多数智能手机上已有的功能：GPS。
它可以帮助记住特定位置，声音环境和首选调整，并在用户位于该区域时自动将其重新拨入。
随着快速发展的移动健康（mHealth）市场的发展，听力行业的未来趋势可能会看到助听器，因为它已经佩戴在耳内或耳后，转变为健康监测器。
利用这项技术，该设备可以配备传感器，直接将有关体温，心率和血氧水平的信息传递给智能手机。
对于所有这些各种应用而言，共同点是适合在助听器中操作的无线技术。
对于与智能手机接口的技术，它必须是蓝牙低功耗（BLE）等既定标准。
十多年来，安森美半导体一直致力于开发针对助听器优化的DSP技术，采用高度集成的片上系统（SoC）。
Ezairo®7100系列助听器处理器于2013年4月推出，能够直接与大多数BLE无线电接口连接，并以业界领先的电源效率运行，这是现代助听器的关键要求。
今年在德国汉诺威举行的国际助听器声学家大会（EUHA）上（10月15日至17日），安森美半导体将为助听器制造商展示我们的听力学DSP解决方案。
我们期待展示我们最新的DSP如何通过BLE链路与智能手机进行无线通信，并展示如何利用这项技术大大改善助听器用户的生活。

Approximately 5% of the world population suffers from a degree of hearing loss which could be corrected through the use of hearing aids. Shockingly, only 4% of this group will actually purchase a hearing aid, due mostly to the cost of the device and the associated negative stigma of old age. Though a simple solution to an irritating problem, many patients will only revert to wearing a hearing aid if absolutely necessary, an issue that ON Semiconductor is targeting through advancements with wireless technology.

To minimize the visual impact of wearing a hearing aid, ON Semiconductor digital signal processing (DSP) technology is evolving to enable wireless connectivity with ancillary devices, including smartphones. Being able to control one’s hearing aids via applications running on a smartphone is a quantum leap for this industry and makes world of difference for the hearing aid users. In addition to being more discrete, this functionality allows the user easier, more direct control over their hearing aid device. For instance, the listening program that is in use on the hearing aid (normal, for noisy situations, for music, in a phone call, etc.) can now be clearly displayed on the smartphone. Some listening parameters can even be adjusted by the user directly on the smartphone. Also, monitoring the device’s performance, like battery level, estimated remaining operating time, etc… can easily be made available to the user. Additional benefits take advantage of functionality already present on most smartphones: the GPS. It can help remember specific locations, their sound environments and preferred adjustments and dial those back in automatically when the user is in that area.
Following suit with the rapidly developing mobile health (mHealth) market, future trends in the hearing industry could see the hearing aid, given that it is already worn in or behind the ear, transformed into a health monitor. With this technology, the device could be equipped with sensors to relay information on body temperature, heart rate, and blood oxygen levels directly to a smartphone.

For all these various applications to work, the common denominator is wireless technology that is suitable to operate in a hearing aid. For that technology to interface with smartphones, it must be of an established standard like Bluetooth Low Energy (BLE). ON Semiconductor has been developing DSP technology optimized for hearing aids for over a decade, in the form of highly-integrated systems-on-chips (SoC). Launched in April 2013, the Ezairo® 7100 family of hearing aid processors is capable of interfacing directly with most BLE radios and operates with industry-leading power efficiency, a critical requirement of modern hearing aids.

This year at the International Congress of Hearing Aid Acousticians (EUHA) in Hannover, Germany (October 15-17th) ON Semiconductor will exhibit our audiology DSP solutions for hearing aid manufacturers. We look forward to demonstrating how our latest DSPs are able to communicate wirelessly with smartphones over a BLE link, and show how this technology can be used to greatly improve the lives of hearing aid users.
