ON Semiconductor has added two new devices to its RHYTHM family of preconfigured Digital Signal Processing (DSP) systems designed specifically for use in hearing aid devices - the RHYTHM R3920 and RHYTHM 3110.

RHYTHM R3920 is a 16-channel device that is equipped with advanced algorithms for high-end applications. RHYTHM R3110, meanwhile, brings new features such as noise reduction and feedback cancelation to the entry-level market sector. Both new devices meet the stringent demands of hearing aid designs in all form factors, balancing high performance with energy efficiency.


R3920 supports today’s advanced hearing aids with its feature set and flexibility. The device features 16-channels of wide dynamic range compression (WDRC), providing audiologists the freedom of fine granularity fitting. The iSceneDetect environmental classification algorithm on R3920 discerns various sound environments and then selects the most appropriate mode automatically for a high-quality, custom audio experience. Impulse noise reduction, another new feature on R3920, monitors and attenuates sharp, impulsive noises such as clattering dishes that could otherwise be very uncomfortable for hearing aid users. For hearing aid manufacturers, R3920 can use the same shells, schematics and designs as the existing R3910 eight-channel DSP from ON Semiconductor, which can help an existing customer get product to market very quickly and easily.

R3110 brings noise reduction and feedback cancellation to hearing aids in emerging geographies and entry-level markets. R3110 is a turnkey solution that does not require computer fitting or extensive infrastructure, facilitating adoption in these markets. With a pre-fit set of audiology parameters, R3110 eliminates the need for software tools and training, simplifying the deployment process. A number of modes can be configured, such as single or dual-microphone, tinnitus masking, or telecoil.

The complete portfolio of hearing aid products from ON Semiconductor includes both programmable and preconfigured DSP systems, featuring high-precision sound, ultra-low power consumption, and wireless capability, to address the needs of all hearing aid manufacturers.
