RHYTHM R3710

Preconfigured DSP System

Description

RHYTHM

t 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 iSceneDetect

t

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.

iLog

t 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.

Evoke

t 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.
