Pre-Fit DSP Solution for Hearing Aids

Favorite

Overview

The RHYTHM™ R3110 hybrid from ON Semiconductor is a pre−fit DSP system that is based on a two−channel compression circuit and designed for entry level hearing aids. With no need for software configuration nor that of storing audiology parameters via computer fitting, R3110 is a simple, cost−effective solution with many features found in high−end hearing aids, including Adaptive Noise Reductionand Adaptive Feedback Cancellation.

R3110 is targeted at replacing aging analog solutions; it offers the same ease of use, yet provides the superior performance of digital technology.

  • Hearing Aids
  • Pre-Fit Audiology Parameters: All built−in sound processing algorithms are preprogrammed for a wide variety of form-factors and to fit a wide range of hearing loss profiles. The device can also be configured for additional use-cases through hardware settings.
  • Trimmer-Based Fitting: Up to four trimmers can be deployed, offering manufacturers the capability to modify most parameters that are important for patient fitting
  • Mode Control: Provides a variety of user control options: momentary or static switches, as well as an analog volume control
  • Adaptive Feedback Canceller: Automatically reduces acoustic feedback. It allows for an increase in stable gain while minimizing artifacts for music and tonal input signals
  • Automatic Telecoil Support: Supports the use of telecoil devices, enabled either automatically with a magnetic sensitive switch or via an external switch
  • Adaptive Noise Reduction: The adaptive noise reduction algorithm monitors signal and noise activities in 32 individual bands and carefully reduces noise
  • Tinnitus Masking: A noise source can be enabled to mask tinnitus. The noise level is adjustable and mixed with the audio path. Spectral shaping is also possible using the high−cut and low−cut filters.
