Abstract : The Aerospace Medical Panel of the Advisory Group for Aerospace Research and Development (AGARD) held a Symposium entitled 'Audio Effectiveness in Aviation', in Copenhagen, Denmark, 7-11 October 1996. It was held in order to address concerns that, while effective voice communications and aural signals are important in military and civil aviation, their implementations are often less than satisfactory in modern aircraft. Factors that influence this are: (a) in many cases audio communications systems in aircraft are based on design concepts that are dated and do not take advantage of recent advances in the area; (b) the noise environments in which the aviator performs often cause acoustic interference with attempts to communicate by means of auditory channels; (c) prolonged exposure to those same noise environments causes temporary and even permanent hearing impairment to the operator; (d) audio signals used as warnings, cautions and advisories are non-standardized and not optimally designed; (e) often audio displays are designed without adequate consideration being given to how they will be integrated into the aircraft systems within which they will function.
