Effect of peripheral hearing loss on the masking level difference
J. Jerger, D. Brown and S. Smith
The effects of both symmetric and asymmetric peripheral hearing loss on the
masking level difference (MLD) at 500 Hz were studied in 651 subjects with
conductive or sensorineural hearing loss and 270 normal controls. The data
supported the hypothesis that the modification in MLD due to peripheral
hearing loss results from deterioration in threshold in the antiphasic
condition. These results provide correction factors for the normal MLD
range as functions of boundary frequency of sensorineural loss above 500 Hz
and degree of both symmetric and asymmetric sensitivity loss at 500 Hz in
both subjects with conductive hearing loss and those with sensorineural
hearing loss.
