Speechreading ability was investigated among hearing aid users with different time of onset and different degree of hearing loss. Audio-visual and visual-only performance were assessed. One group of subjects had been hearing-impaired for a large part of their lives, and the impairments appeared early in life. The other group of subjects had been impaired for a fewer number of years, and the impairments appeared later in life. Differences between the groups were obtained. There was no significant difference on the audio-visual test between the groups in spite of the fact that the early onset group scored very poorly auditorily. However, the early-onset group performed significantly better on the visual test. It was concluded that the visual information constituted the dominant coding strategy for the early onset group. An interpretation chiefly in terms of early onset may be the most appropriate, since dB loss variations as such are not related to speechreading skill.
研究了不同发病时间和不同听力损失程度的助听器使用者的唇读能力。评估了视听和仅视觉模式下的表现。一组受试者在生命的大部分时间里都有听力障碍，且这些障碍在早年出现。另一组受试者听力受损的时间较短，且这些障碍在晚年出现。得出了两组之间的差异。尽管早发性组在听觉测试中得分很低，但两组在视听测试中没有显著差异。然而，早发性组在视觉测试中的表现明显更好。得出的结论是，视觉信息构成了早发性组的主要编码策略。主要根据发病早来进行解释可能是最合适的，因为单纯的分贝损失变化与唇读技能无关。
