Auditory Display Typical Use

Auditory displays are typically used as warnings, alerts, and alarms. Attempts have been made to standardize the meaning of these terms. Bliss and Gibson (1998) give the following definitions.

  • Warning - A hazardous event may occur if circumstances prevail.
  • Alert - A hazardous event is expected to occur soon if nothing is changed.
  • Alarm - A hazardous event is occurring and requires immediate response.

These distinctions are used with other standards and design criteria in complex systems such as airplane cockpits, air traffic control systems, nuclear power plant control rooms, and medical monitoring equipment.

Aircraft Cockpit

Aircraft cockpits have complex visual and auditory displays. The number of these displays has steadily increased, as aircraft have become more technically sophisticated.
