1. Microphone
New microphone design is less prone to shock and feedback-related problems
Microphone diaphragms are perpendicular to receiver diaphragm, eliminating sympathetic vibrations that can cause feedback
Microphones are offset from port openings, reducing the potential for moisture problems
2. Receiver
Filterless receiver is less susceptible to shock and moisture damage
New receivers provide a smoother frequency response, resulting in better sound quality
3. DSP Chip
Newest generation of SONIC's patented multiplicative AGC processing and envelope mapping resulting in unprecedented sound quality
Uses efficient FFT+Finite Impulse Response processing, resulting in lower battery consumption
Group time delay of <6ms, providing real-time processing of sound
Dual A/D converters allow for multiple omni microphone directionality
E2 memory size increased 14,000% over previous SOIC DSP, allowing for implementation of more complex features
4. Telecoil
Calibrated to match the omni microphone response
New telecoil design reduces electro-magnetic interference and "hum"(60 cycle).
5. Programming Pins
Improved design ensures communication between hearing aid and fitting system
