RHYTHM SB3229  
Preconfigured DSP System  
for Hearings Aids  
Description  
The RHYTHMt SB3229 hybrid from ON Semiconductor is  
a trimmer−configurable DSP system based on a four−channel  
compression circuit featuring a feedback cancellation algorithm.  
Based on a phase cancellation method, SB3229’s adaptive feedback  
reduction algorithm provides added stable gain to enable extra gain  
and user comfort. It features rapid adjustment for dynamic feedback  
situations and resistance to tonal inputs.

HYBRID  
CASE 127DN  
In addition to these adaptive algorithms, SB3229 also supports the  
following features: up to four channel WDRC, low−distortion  
compression limiting, cross fading between audio paths for click−free  
memory changes, eight−band graphic equalizer, eight configurable  
generic biquad filters, programming speed enhancements, in−channel  
squelch to attenuate microphone and circuit noise in quiet  
environments, optional peak clipping, flexible compression  
adjustments, volume control, rocker switch, noise generation for  
Tinnitus treatment, and industry−leading security features to avoid  
cloning and software piracy.
