ABSTRACT
A questionnaire survey was undertaken of patients who had recently purchased a private hearing aid. They were asked their reasons for choosing a private aid in preference to an NHS aid. Cosmetic considerations and the failings of Health Service provisions were the most commonly cited reasons.

An experiment was performed using low-level ultrasound in an attempt to inhibit tinnitus during and after stimulation. The method used a double-blind crossover technique with a placebo. Forty subjects were tested, and they generally reported little or no change in their tinnitus, the results from placebo and ultrasound not being statistically different. It cannot be concluded, therefore, that the ultrasound we were using has any beneficial effect on tinnitus. These results do not confirm the findings of the pilot study using the same ultrasound devices (Carrick et al., 1986).

The evaluation of high-frequency thresholds above 8 kHz has not always been accepted as a reliable, reproducible measure in routine audiological clinics. Using standard equipment we have shown that thresholds at 10 kHz and 12 kHz can be so measured, and that 16 kHz thresholds may be determined with the same degree of reliability with only the minor addition of a signal generator and a set of high performance earphones.
