Now that it is known to be abnormal for the pitch of a pure tone above 1000 c/s to depend on intensity (Strange, 1955(Strange, , 1956 it becomes important to know more about those types of deafness which accompany this pitch defect, especially with regard to the abnormally large gain in loudness for a given increase in intensity which is known as recruitment of loudness. The technique of alternate binaural loudness balance (Fowler, 1936) is a sensitive way of exploring the loudness function of a deaf ear, but it can only be used when the subject has good hearing in the other ear. The author has studied a group of such subjects, and, in the course of extended tests, has examined the pitchintensity dependence for each ear separately, and has performed loudness balance tests as between the two ears. This paper is concerned with these experiments. METHODSThe apparatu8 was designed to produce two pure tones each lasting for 1 sec in quick succession, the next pair of tones following after an interval of 1-5-2 sec. The tones were produced by a pair of Hewlett-Packard 205 A.G. oscillators, and were independently controUed in frequency and intensity. The two tones could be led to a single earphone, in which case the apparatus was exactly as described before (Strange, 1955(Strange, , 1956), or else it was possible to lead the first tone ofeach pair to one earphone of a matched 4026A S.T. and C. head set, and the second tone to the other. The same Amplivox audiometer was used as before.The subjectd each possessed one ear with very much better hearing than the other, and were selected on the basis of the air conduction threshold audiogram. The only thing in common between the defective ears of the various subjects was irregularity of the threshold audiogram, not its shape. Only one of these subjects had previous experience of the pitch tests, H.C.W. (Strange, 1956). One subject, V.P., was a woman.Technique. Pitch tests were carried out as described before (Strange, 1955(Strange, , 1956) always using a single earphone and testing one ear at a time. Frequencies between 125 and 6000 C/s were examined as follows. The subject heard a series ofpairs ofpure tones in one ear, and his task was to record a forced-choice comparison ofthe pitch of the second tone of each pair with the pitch of the standard first tone. This procedure is sometimes called the method of constant stimuli, and by
