A newly-released international standard for medical equipment alarms, IEC 60601-1-8, incorporates a long-standing suggestion that alarms should indicate their source through distinctive melodies. In this paper we examine this suggestion. We describe the proposed alarms, outline the history of the idea, and review recent research on the effectiveness of the alarms, some of it performed in our la...

The auditory hazard assessment algorithm for the human (AHAAH), developed by the US Army Research Laboratory, is theoretically based and has been demonstrated to rate hazard from intense sounds much more accurately than existing methods. The AHAAH model operates in a PC level computer and analyses hazard in the time domain. In addition to reproducing the conductive path from air to the cochlea ...

Noise-induced hearing loss (NIHL) continues to be one of the most prevalent occupational conditions and occurs across a wide spectrum of industries. Occupational hearing loss is preventable through a hierarchy of controls, which prioritize the use of engineering controls over administrative controls and personal protective equipment. The occupational and environmental medicine (OEM) physician w...

The subjective benefit of middle ear implantation was studied in a group of 23 hearing-impaired patients who could not use conventional hearing aids owing to severe chronic external otitis. Changes in hearing disability (Abbreviated Profile of Hearing Aid Benefit [APHAB]) and changes in quality of life (Glasgow Benefit Inventory [GBI]) were determined. Mean benefit value on the APHAB for the su...

The data for the present investigation were collected between August, 1951, and August, 1956, in the Butterley Company's works at Codnor Park. In some of the shops of these works the noise is so intense that outsiders experience it as unpleasant and in some spots even as unbearable. During the period mentioned no protective devices were in use, largely because the workers found many of the exis...
