Even non-techies are aware of the massive takeover of the Internet of Things (IoT) and how wireless technology is now being implemented in everything from televisions to children’s toys. Medical devices, like hearing aids, are no exception. This technology can give patients more comfort as it now enables user control from apps running on smartphones. And providing such improved user experience can transform a hearing aid from a device someone needs to wear, at times reluctantly, into one they’ll want to wear.
Ezairo ®7150 SL is an audiology processor, augmented with Bluetooth®-technology and certified to the standard. It supports advanced wireless technology in hearing aids and cochlear implants. Based on the programmable Ezairo 7100 digital signal processing (DSP) platform, the miniature hybrid module features a high-precision quad-core architecture that delivers 375 MIPS without sacrificing power consumption.Ezairo 7150 SL provides multi-protocol wireless support, and is optimized for 2.4 GHz applications including Bluetooth® Low-Energy (BLE). To store important hearing aid parameters, Ezairo 7150 SL provides 2 Mb of non-volatile memory EEPROM (EA2M).
ON Semiconductor offers a complete reference design of an Ezairo 7150 SL-based behind-the-ear (BTE) hearing aid, with hardware, firmware, and software. This reference design supports two advanced wireless features: Control over Bluetooth Low Energy (CoBLE) and stereo audio streaming.
Using CoBLE, hearing aid users can control a number of features on their device directly from their smartphone. They can change the volume or settings on their device, be alerted to incoming calls or text messages, and even locate a misplaced hearing aid with Find Me features. Based on a 2.4 GHz proprietary protocol, the stereo audio streaming feature allows users to hear audio from any external source like televisions or car radios through the use of a small transmitter dongle. That dongle can also operate in remote microphone mode, further enhancing the user’s listening experience in challenging situations, like noisy environments or class rooms where the speaker might be far away.

At this year’s EUHA Congress in Nürnberg, Germany ON Semiconductor will launch its latest solutions for hearing health: Ezairo 7150 SL and HPM10, a Power Management Integrated Circuit (PMIC) which enables rechargeable battery technology in hearing aids. Together, these solutions will help bring a new generation of more sophisticated, user-friendly devices to the hearing-impaired worldwide.
