The protective effect of a conductive hearing loss in workers exposed to industrial noise.

There is controversy as to whether a conductive hearing loss protects the inner ear from the effects of loud noise. A retrospective study was carried out on 24 patients with a combination of unilateral conductive hearing loss and noise-induced hearing loss. This allowed subjects to act as their own controls. There was no statistical difference in thresholds between the two ears; possible explanations for this finding are discussed.

Noise levels and exposure patterns to do-it-yourself power tools.

The noise levels produced by a variety of do-it-yourself power tools were measured in a real-life situation. Most of the devices tested produced noise of 100 dB(A) or greater at the user's ear. A questionnaire was issued to 100 males who used these devices. The vast majority used the devices infrequently and therefore are unlikely to be directly at risk of hearing damage. A group of users who may be more at risk from using power tools in the home are those who are, or have been exposed to occupational noise.

Simpson-Edinburgh low-pressure air bed: an early clinical evaluation.

A simple, inexpensive low-pressure air bed has been developed for use in situations where decubitus ulcers may arise. This bed is currently being evaluated in patients with spinal injuries, both in the hospital situation and in the home. Early experience is highly encouraging as regular turning of the patient can be safely omitted. We feel that widespread use of this bed could greatly decrease the incidence of pressure sores.
