Auditory warnings are used in a variety of settings such as hospitals and the cockpits of modern military aircraft. This paper describes a study in which sets of auditory warnings comprised of speech, auditory icons (environmental sounds) and abstract sounds were compared with respect to ease of learning and retention. Speech warnings and auditory icons were learnt and retained with equal ease, while abstract-sound warnings were found to be learnt and retained with far greater difficulty.
