ON Semiconductor launches Rhythm TM R3710 pre-configured DSP system

A supplier of high performance silicon solutions, ON Semiconductor has introduced the Rhythm R3710, a new pre-configured Digital Signal Processing (DSP) system that has been designed specifically for Invisible-in-Canal (IIC) hearing aid devices. The Rhythm R3710 hybrid incorporates advanced speech and audio signal processing algorithms and features advanced miniaturised packaging techniques, which enable hearing aid manufacturers to develop highly discrete products intended to be placed deep in the ear canal.

The device measures 4.57 mm x 3.12 mm x 1.52 mm (0.180 x 0.123 x 0.060 in.), which makes it 20 percent smaller than existing Rhythm family hybrids, and is the industry’s smallest hybrid form-factor.

Key features of the R3710 include: up to 8 wide dynamic range compression (WDRC) channels: an iSceneDetect environmental classification algorithm which utomatically optimises the hearing aid to maximise comfort and audibility by analysing the hearing aid user’s acoustic environment; an adaptive noise reduction algorithm that monitors noise levels independently in 128 individual bands and employs advanced psychoacoustic models to provide user comfort ; iLogTM Datalogging that enables logging of various parameters such as program selection, volume setting and ambient sound levels and adaptive feedback cancellation. This automatically reduces acoustic feedback and allows for an increase in the stable gain while minimising artifacts for music and tonal input signals

“Rhythm R3710 is able to support the development of increasingly popular Invisible-in-Canal hearing aid devices,” said Michel De Mey, senior director Hearing Health products at ON Semiconductor. “By leveraging ON Semiconductor’s experience in ultra-low-power signal processing and miniaturised packaging technology, we can offer a pre-configured DSP system that uniquely addresses the form-factor and performance needs of this growth market.”

Rhythm R3710 is E1 RoHS compliant and uses ON Semiconductor’s thinSTAXTM packaging.
