Abstract
The phenomenon of central presbycusis has been investigated employing a central auditory battery in elderly individuals with essentially normul hearing. The studies indicate a progressive loss in central auditory competence measured by simultaneous binaural challenges and frequency and temporal distortion tests. The rate of failure is related to age, on the whole, but there is increasing variability from the normals with seniority. The hearing disability in noise or speech competitive environments is explained by these data. Auditory disabilities related to poor articulation and rapid speech presentation are identified by other tests in the battery. Central presbycusis, in addition to the peripheral form, does exist and further compounds the hearing disorder in many elderly.
