HEARING HEALTH CARE
We have extensive experience in:
  • Architecture, Design and Optimization of custom integrated circuits for hearing aids
  • Analog ASIC implementations provide ultra-low power operation, lower development cost.
  • Multi-Band Compression technology:
  Multi-Band compression splits the audio spectrum into two or more frequency
                bands and applies programmable compression to each band separately.
  Programmable Multi-Band compression adaptively compensates for frequency                         dependent hearing losses on an individualized basis.
  • RF Inductive Power-Link technology:
  Remote recharging of hearing aid batteries
  Powering implanted hearing aid devices
  • RF communications between control devices, left/right hearing aids or external DSP audio processing module.
