The Importance of Visual Control in Auditive Speech Communication among Persons with Presbyacusis

Summary/Abstract: The main way of speech reception is auditive. This is supplemented by visual reception, especially among persons with impaired hearing, but also significant for persons whose hearing is normal. The sense of sight is of great importance for understanding speech when information gained through hearing is impeded. Visual speech perception is even more important in cases of severe hearing deficiency, especially among persons suffering from presbycusis because they have a hearing defect and because vocal speech communication is taking place under bad environmental conditions. The success of reading a speech from lips and face is very important for persons with presbycusis, and it may be impeded by a wide spectrum of disruptive factors (fast speech that hinders lip-reading, weak lighting, distance from the speaker, various visual obstacles). Specific changes in the eyes and CNS could also be disrupting. The research included 134 examinees of both genders suffering from presbycusis. They were examined by the PIPSL questionnaire. This research required two scales from the questionnaire, both connected with visual perception (understanding speech by visual perception and understanding speech without visual information). Factor analyses gave five factors that describe the field of understanding speech with visual perception and without visual perception.
