Biomimetic direction of arrival estimation for resolving front-back confusions in hearing aids [PDF]
, 2015 Sound sources at the same angle in front or behind a two-microphone array (e.g., bilateral hearing aids) produce the same time delay and two estimates for the direction of arrival: A front-back confusion.
