Abstract
The quantal psychophysical method was used to obtain psychometric functions for differential intensity sensitivity at 2 sensation levels (10 and 40 db), at 2 frequencies (1000 and 4000 cps), in 10 normals and 10 cases of hearing losses with normal hearing at 1000 cps but losses at 4000 cps plus recruitment. At 1000 cps where control subjects had normal acuity but experimental subjects had hearing loss accompanied by loudness recruitment, differential sensitivity was significantly better in the experimental group.Keywords
