Recruitment of loudness in the differential diagnosis of end‐organ and nerve fibre deafness

LXXVII Auditory Fatigue in Differentiating Aural Pathology

“…The normal hearing and conductive loss groups exhibited a greater temporary threshold shift and a slower recovery time for the stimulating frequency than did the neural involvements. 5. The recruitment factor, as defined in this study, did not differentiate between the etiological groups.…”

Modern Developments in Pure Tone Audiometry and Their Application to the Clinical Diagnosis of End-Organ Deafness

“…Thus Lund-Iversen (1952) of Oslo and Liden and Nilsson (1950) of Stockholm who have used methods involving sustained stimuli, report anomalous results. On the other hand, Eby and Williams (1951) of the Mayo Clinic, in one of the few adequate repetitions of the original investigation, used the testing technique, then specified, in an adequate number of cases, including 32 of Meniere's disease and 6 of VHIth nerve neuroma or cerebello-pontine angle tumour, and obtained results which were entirely in agreement with the original series.…”

An Auditory Loudness Recruitment Test Battery: Analysis and Comparison of Subtests

“…In general, smaller DL's and RCL's are found above 2000 cps than below that frequency. 3. In general, the extent of the DL is inversely proportional to the sensation level of the stimulus tone, while the number of correct speech sound discriminations is di¬ rectly proportional to the sensation level.…”
