Auditory warnings in noisy environments.
Auditory warnings are used throughout industry, transport, and the medical world. Despite the fact that auditory warnings frequently have to compete with intense and complex noise backgrounds, their use is widespread. This article reviews research and practice in the area of auditory warning design and implementation with particular emphasis on noisy environments. Auditory and visual modalities as warning senses are compared, and ergonomic methods of producing warnings which are acoustically tailored to their environments are reviewed. Developments in design approaches are reviewed with examples of both traditional types of warnings and digital, contemporary warning styles. Other issues such as false alarms and the minimisation of warning numbers are briefly considered.
