Introduction  Pure-tone threshold audiometry provides us with a restricted knowledge about the hearing function and, especially, about the hearing of normal speech. However, the indispensable information on the hearing capacity for different frequencies and thus on the condition of every part of the basilar membrane can only be obtained by puretone audiometry. Here, too, the speech range will be part of our main concern, and for this reason our method of measuring should be as accurate as possible in regard to both intensity and the frequencies involved. The same holds true for the higher frequencies when we wish to detect an impending noise trauma.For such demands octave audiometry is an imperfect means, as with this technique a very restricted number of frequencies are tested and the parts of the basilar membrane lying between these frequencies are neglected. Thus only a rough idea of the hearing abilities is obtained. However
