What is it about?

Numerous researchers have explored the advantages of listening with two ears compared to one ear using various methodologies. However, none of these studies have clarified which type of material is most suitable for such evaluations. Some researchers have used monosyllabic words, others have used disyllabic words, and some have employed sentences. In this study, we examined all three types of materials from different perspectives to determine which speech material is best for assessing binaural hearing. We then applied the chosen speech material to both individuals with normal hearing to establish normative data and bilateral cochlear implant users, along with a localization test, to explore any potential relationship.

Why is it important?

This study's findings have implications for both research and clinical practice, offering valuable insights into the optimal methods for assessing binaural hearing. The study addresses the lack of clarity in previous research regarding the most appropriate speech material for assessing binaural hearing advantages. By investigating the suitability of various materials (monosyllabic words, disyllabic words, and sentences), it fills an important gap in the literature. Enhancing comparability: With previous studies using different methodologies and materials, comparing their results becomes challenging. This study's findings can provide a standardized approach and enhance comparability between different studies, contributing to a more comprehensive understanding of binaural hearing benefits. Informing clinical practice: By determining the most effective speech material for assessing binaural hearing, the study's results can be directly applicable in clinical settings. Clinical audiologists can use this information to evaluate patients' binaural hearing abilities better. Establishing normative data: By obtaining normative data from individuals with normal hearing using the chosen speech material, the study establishes a baseline for comparison.


As my master's thesis, this study holds a special significance for me. I take great satisfaction in the fact that we are addressing a previously unexplored question, and our research has the potential to contribute to both clinical and research domains.
