Abstract: Directional microphones in hearing aids have changed considerably over the years. Signia has consistently been in the forefront of directional technology for hearing aids. Technological advancements in microphone design, digital processing and algorithms have all factored into how hearing aids perform directional tasks. This progress in directional performance has also been shown to provide improvements in wearer benefit for speech understanding in noise.
In this course, we will discuss Signia’s evolutions in directional technology throughout the years, the most current implementations used today and the wearer benefit that can be realized with this technology.

Learning Objectives:

  • Upon completion, participant will be able to differentiate between traditional directionality and beamforming.
  • Upon completion, participant will be able to discuss signal-to-ratio advantages of directional microphones..
  • Upon completion, participant will be able to discuss the contribution of wireless transmission to directional microphone.
