Participating in conversation is an integral part of human social interaction, and having a hearing impairment makes it difficult to communicate, especially in noisy environments. This can lead to hearing-impaired individuals withdrawing from social interactions, eventually leading to social isolation. One of the most important outcomes of hearing rehabilitation, therefore, is to regain people's ability to partake in social interactions, but we often have to generalize results from tests that only involve one part of communication, either comprehension or production. Conversation, however, involves an overlap between the two, and it is a dynamic feedback process between interlocutors who may adapt to each other's difficulties to alleviate communication barriers. This thesis aimed to find objective measures of conversational dynamics that varied in a systematic way when people experienced increased communication difficulty. In four experiments, we investigated the effects of noise on conversational dynamics between normal-hearing pairs of interlocutors, and between normal-hearing/hearing-impaired pairs either seated separately or face-to-face. When communicating in noise, hearing-impaired individuals were less precise in their timing of turn-taking, they produced longer utterances, and they spoke slower and louder. When receiving compensation for their hearing loss, hearing-impaired individuals were able to time their responses with higher precision, and they produced shorter utterances. The results are promising for the prospect of using conversational dynamics as objective measures for evaluating the performance of different hearing assistive devices' processing strategies and features.
