The Pamphlet Collection of Sir Robert Stout: Volume 38



The above cases were not consecutive, but fairly represent the result in a number of cases examined. I feel it my duty to say that I have met with several cases in which the Audiphone did not give entire satisfactory results, but I think the failures may very readily be accounted for in each case. One is that of a lady aged 68, of catarrhal deafness, the failure was altogether owing to the looseness of her artificial teeth, and in others to various causes plainly perceptible.

I may also mention that in all cases examined, other instruments of ancient and recent invention, were also tested or tried, but in no instance save one was any found as effectual as the Audiphone. I refer to the case of the lady with the loose artificial teeth. In this case the ordinary conversation tube was found the only available aid.
