Intelligent Microphone for eCall

Intelligent Microphone technology has been incorporated into the eCall Units of several providers. This technology meets all the Type 1 Double Talk performance requirements by EU and Russia:

  • Reduces the echo (the sound feedback loop) by about 30dB, making it easier to continue
    the conversation.
    Beamforming allows the reduction of even non-linear echo arising from speaker distortion
  • Automatically corrects the individual variables such as sensitivity and assembly of
    mic elements, ensuring the optimal echo removal for each device
  • Removes the echo from the beginning allowing double talk from the start (requires prior tuning to suit the position of the microphones and speaker)

eCall is a European initiative intended to bring rapid assistance to motorists involved in a collision
anywhere in the European Union (EU).
The regulation requires all new cars sold in the EU to be equipped with eCall technology from April 2018.
In the event of a serious accident, eCall automatically dials 112 – Europe’s single emergency number.
