The fundamental basis and technical aspects involved in integrating two relatively new technologies in the design of communication headsets are reviewed. The first technology, known as active noise reduction (ANR), can improve speech intelligibility by reducing the amount of interfering noise from the environment. The second technology, known as binaural technology, allows the simulation of 3D auditory displays, which can enhance speech intelligibility and situational awareness over monophonic listening.
