More seriously rather, I've had my NHS hearing aids updated. Instead of Oticons with thick tubes and earmoulds, it's Siemens with thin tubes and in the ear. Best of all there's volume control!
Things seem to be improved since audiology has been outsourced from the hospital trust to local suppliers. The one I used was more informative and proactive.
Getting round to the technical, the volume has three settings, the steps being 2 dB. I remarked, that seemed quite a lot, but was told that an increase of 6 dB, (I hope I've got this right) was perceived as half that.
Strange!
