RHYTHM R3110
Pre-fit DSP Solution for
Hearing Aids
Introduction
The RHYTHMt R3110 hybrid from ON Semiconductor is a
preâfit DSP system that is based on a twoâchannel 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, costâeffective solution with many features
found in highâend hearing aids, including Adaptive Noise Reduction
and 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. In its simplest
configuration, a hearing aid build using R3110 only requires four
external electronic components.
Key Features and Benefits
⢠PreâFit Audiology Parametersâ All soundâprocessing algorithms
are preprogrammed to enable manufacturers to develop hearing aids
in a variety of formâfactors and to fit a wide range of hearing loss
profiles. The device can also be configured for additional useâcases
through hardware settings.
⢠TrimmerâBased Fittingâ Up to four trimmers can be deployed,
offering manufacturers the capability to modify most parameters that
are important for patient fitting.
⢠Mode Controlâ Provides a variety of user control options:
momentary or static switches, as well as an analog volume control.
⢠Adaptive Feedback Cancellerâ Automatically reduces acoustic
feedback. It allows for an increase in stable gain while minimizing
artifacts for music and tonal input signals
⢠Automatic Telecoil Supportâ Supports the use of telecoil devices,
enabled either automatically with a magnetic sensitive switch or via
an external switch
⢠Adaptive Noise Reductionâ The adaptive noise reduction algorithm
monitors signal and noise activities in 32 individual bands and
carefully reduces noise
⢠Tinnitus Maskingâ 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 highâcut and lowâcut filters.
