Recently, China's first smart digital hearing aid chip developed by the Institute of Microelectronics, Chinese Academy of Sciences, which is the core of the first hearing aid core SoC chip, is a truly single-chip fully integrated hearing aid solutions.
The chip has passed the hearing aid industry test standards, the performance, power consumption indicators to meet the needs of the international mid-range hearing aids. This achievement is of great significance to promoting the hearing aid industry in our country from manufacturing to innovation and development.
The Hearing Aid SoC chip uses a single chip fully integrated solution, of which, low noise AFE includes adaptive pre-amplifier PGA and low noise 16-bit ADC; low-power DSP includes a dedicated instruction set processor ASIP and several coprocessors. Based on the SoC chip, just equipped with a microphone, speaker, EEPROM, zinc-empty battery and a small amount of capacitance, you can build a typical hearing aid system. The SoC chip can also be programmed, used in voice acquisition, voice noise reduction and other areas.
