ON Semi's pre-configured DSP System for Invisible-in-Canal hearing aids

Measuring 4.57 mm x 3.12 mm x 1.52 mm (0.180 x 0.123 x 0.060 in.), the Rhythm R3710 hybrid is 20 percent smaller than existing Rhythm family hybrids, and is the industry’s smallest hybrid form-factor.

RHYTHM R3710 Key Features:
• 8-Channel WDRC: Up to 8 wide dynamic range compression channels
• iSceneDetect Environmental Classification Algorithm: Automatically optimises the hearing aid to maximise comfort and audibility by analysing the hearing aid user’s acoustic environment
• Adaptive Noise Reduction Algorithm: Monitors noise levels independently in 128 individual bands and employs advanced psychoacoustic models to provide user comfort
• iLog Datalogging: Enables logging of various parameters such as program selection, volume setting and ambient sound levels
• Adaptive Feedback Cancellation: Automatically reduces acoustic feedback and allows for an increase in the stable gain while minimising artefacts for music and tonal input signals

“Rhythm R3710 is a perfect solution 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 and expertise in both ultra-low-power signal processing and miniaturised packaging technology, the company 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.
