RHYTHM R3920
Preconfigured DSP System
for Hearing Aids
Description
RHYTHMt R3920 is a preconfigured hearing health processor
based on a DSP platform. Featuring 16 channels of Wide Dynamic
Range Compression and Impulse Noise Reduction, R3920
encompasses a rich set of advanced sound processing algorithms and
is ideal for high end, full-featured hearing aids. The R3920 hybrid is
available in one of the industry’s smallest form-factors and is
well-suited for all hearing aid types, including those placed deep in the
ear canal.

Wide Dynamic Range Compression (WDRC) − R3920 contains
16 Channels of Wide Dynamic Range Compression, each with
individual settings for Squelch Attentuation and Threshold, Low
Level Gain, High Level Gain, Upper and Lower Thresholds, and
Compression Ratio. Independent level detectors for both Squelch and
WDRC are available with customizable attack and release times set in
each channel.
Impulse Noise Reduction (INR) – Loud, impulsive sounds in the
environment such as slamming doors, dropped items, or clattering
dishes can become uncomfortably or dangerously loud in a traditional
hearing aid. The INR algorithm actively monitors and processes the
incoming acoustic signal for such sounds. It ensures that the output
sound preserves the integrity of the speech signal and is descriptive of
the environment, while maintaining an optimal comfort level for the
hearing aid user.
Acoustic Environment Classification − iSceneDetectt analyzes
incoming acoustic signals in order to determine the appropriate
classification for a given acoustic environment. Six separate
environments are supported by iSceneDetect: quiet, speech in quiet,
noise, speech in noise, music, and wind. The feature uses this
classification to automatically adjust settings of other features for
optimum audio performance.
iLogt 4.0 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 manufacturer can
program the fitting system to retrieve the data for further analysis after
an extensive period of wearing the hearing aid. This allows the
audiologist to fine tune the hearing aid and further counsel the
end-user.
Automatic Adaptive Directionality − The Automatic Adaptive
Directional Microphone (ADM) algorithm automatically reduces the
level of sound sources that originate from behind or to the side of the
hearing aid wearer without affecting sounds from the front. The
algorithm can also gather input from the acoustic iSceneDetect
environmental classifier algorithm and automatically select whether
directionality is needed or not, translating into additional current
savings.

Adaptive Feedback Canceller − Automatically reduces
acoustic feedback. It allows for an increase in the stable gain
while minimizing artifacts for music and tonal input signals.
Additional tuning parameters make for more precise tuning
of the algorithm to the hearing aid. The development tools
for the R3920 offer a special calibration module to help
assess the maximum stable gain in the hearing aid the
manufacturer has built to further optimize the Adaptive
Feedback Canceller algorithm.
Adaptive Noise Reduction − The Adaptive Noise
Reduction algorithm monitors noise levels independently in
128 individual bands and employs advanced psychoacoustic
models to reduce noise and provide user comfort. The
algorithm can be set for varying levels of aggressiveness
from 3 dB up to 12 dB.
Automatic Receiver Detection − For Receiver−in−Canal
(RIC) devices with field replaceable receivers, R3920
allows manufacturers to code different receiver types so
they are automatically recognizable in software, eliminating
potential selection errors.
Tinnitus Masking − R3920 is equipped with a noise
source that can be used to mask tinnitus. The noise can be
shaped and attenuated and then summed into the audio path
either before or after the volume control. A white noise
signal is generated and inserted into the audio path either
before or after the volume control. Filtering can be
performed on the white noise signal in order to shape the
noise signal to a desired frequency and bandwidth. The
tinnitus masker can be used as a stand alone tinnitus making
device or as part of a hearing aid.
EVOKEt Advanced Acoustic Indicators − Allows
hearing aid manufacturers to provide more pleasing,
multi−frequency tones simulating musical notes or chords to
indicate events such as program or volume changes.
In−situ Tone Generator − The narrow−band noise
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.
Other Key Features − R3920 also supports the following
features: FrontWave® directional processing, built−in
feedback path measurement, cross fading between audio
paths for click−free program changes, 16−band graphic
equalizer, 8 generic biquad filters (configurable as
parametric or other filter types), programming speed
enhancements, optional peak clipping, flexible compression
adjustments, direct interfaces to analog or digital volume
control, rocker switch, direct audio input and telecoil.
Rhythm R3920 also encompasses industry−leading security
features to avoid cloning and software piracy.

1. A device must internally provide a hold time of at least 300 ns for the PC_SDA signal to bridge the undefined region of the falling edge of PC_CLK.
2. The maximum tHD;DAT has only to be met if the device does not stretch the LOW period (tLOW) of the PC_CLK signal.
3. A Fast−mode I2C−bus device can be used in a Standard−mode I2C−bus system, but the requirement tSU;DAT P250ns must then be met.
This will automatically be the case if the device does not stretch the LOW period of the PC_CLK signal. If such a device does stretch the
LOW period of the PC_CLK signal, it must output the next data bit to the PC_SDA line tr max + tSU;DAT = 1000 + 250 = 1250 ns (according
to the Standard−mode I2C−bus specification) before the PC_CLK line is released.
4. Cb = total capacitance of one bus line in pF.
