Pixation Corp.
Technology
Hi-Fi Audio
Pixation technologies reproduce speech with high fidelity: 31.25 kHz microphone sampling; 62.5kHz PWM audio out; eight octave bandwidth (3DB: 50Hz to 15.5 kHz)
Low Cost
Pixation technologies can be implemented on low-cost microcontrollers such as the 48MHz Microchip® ATSAMD21E17 using the ARM® Cortex M0+ Processor.
Passive Amplification
Pixation technologies can improve the Speech Intelligibility Index (SII) by raising high frequency speech levels to levels above the microphone equivalent noise levels.
Signal-to-Noise
​
Move beyond wide dynamic range compression with Pixation's controlled acoustic signal expansion technology. This technology greatly improves intelligibility in noisy environments.
​
Dip Listening
Pixation technologies continuously analyzes the sound environment to catch "acoustic glimpses" of speech, especially when fluctuating background noise levels decrease momentarily.
Low Power, Safety
A new level of hearing aid performance: 9 hours (typical) with a rechargeable 110mAh LiPo battery. Sound exposure limited to 85dBA time-weighted average.
