Development Kit Easily Builds Wireless Hearing Aids

ON Semiconductor now offers the Ezairo Preconfigured Suite (Pre Suite), a development toolkit enabling turnkey solutions based on the company’s Ezairo 7100 Digital Signal Processor (DSP). The wireless-enabled Ezairo 7150 SL is the first hybrid module to be supported by the Ezairo Pre Suite, with a firmware bundle that makes it easier to build wireless-enabled hearing aids.


Features include Wide Dynamic Range Compression (WDRC), adaptive noise reduction, support for directional microphones, acoustic feedback cancellation, and environmental classification. Paving the way for easier development of mid-range hearing aids or upcoming Over-the-Counter (OTC) devices, the firmware bundle also provides support for advanced wireless features, opening the door for wireless fitting and advanced user control.


Meeting manufacturers’ specific needs, ON Semiconductor provides a Windows-based software package that acts as a complete end-to-end user interface for developing next-generation hearing aids. Software package features include transducer modeling and calibration, parameter control, and live diagnostic tools. Also on tap is a cross-platform Software Development Kit (SDK) that supports both Windows and mobile platforms including iOS and Android with wired or wireless communications over Bluetooth low energy (BLE) technology.
