RHYTHM R3710
Preconfigured DSP System
Description
RHYTHMt R3710 is a preconfigured DSP system designed
specifically for Invisible−In−Canal (IIC) hearing aid devices.
Available in the industry’s smallest hybrid form−factors, it is well
suited for hearing aid designs that are placed deep in the ear canal.
Using miniaturized advanced packaging techniques,
ON Semiconductor enables hearing aid manufacturers to take
advantage of the highly compact size to produce IIC hearing aids that
fit a greater portion of the market. Featuring iSceneDetectt
environmental classification, adaptive noise reduction, feedback
cancellation, and up to 8−channel WDRC, R3710 provides the
advanced features and performance level typically found in high−end
products.
Acoustic Environment Classification − The iSceneDetect
environmental classification algorithm is capable of analyzing the
hearing aid user’s acoustic environment and automatically optimizes
the hearing aid to maximize comfort and audibility.
iLogt 6.0 Datalogging − Enables the recording of various hearing
aid parameters such as program selection, volume setting and ambient
sound levels. The sampling interval can be configured to record from
every 4 seconds up to once every 60 minutes. The fitting system can
present the data to help the fitting specialist fine tune the hearing aid
and counsel the wearer during follow up visits.
Evoket Advanced Acoustic Indicators − Allows manufacturers
to provide more pleasing, multi−frequency tones simulating musical
notes or chords to indicate events such as program or volume changes.
Adaptive Feedback Canceller − Automatically reduces acoustic
feedback and allows for an increase in the stable gain while
minimizing artifacts for music and tonal input signals.
Adaptive Noise Reduction − The adaptive noise reduction
algorithm on R3710 monitors noise levels independently in 128
individual bands and employs advanced psychoacoustic models to
provide user comfort.
Tinnitus Masking − R3710 is equipped with a noise source that can
be used to mask tinnitus. The noise can be shaped, attenuated, and duty
cycled then summed into the audio path either before or after the
volume control.
In−situ Tone and Noise Generator − The narrow−band noise and
tone stimulus feature can be used for in−situ validation of the hearing
aid fitting. The frequency, level and duration of the stimuli are
individually adjustable.
