研究概览
简要总结
The study aims to develop and validate behavioural and self-reported listening effort measures tailored for Kannada-speaking adults. It involves the creation of a novel Word Identification and Recall Test (WIRT) and the translation and validation of the Extended Effort Assessment Scale (EEAS) into Kannada. The study also aims to establish normative baselines and evaluate these tools among normal-hearing and hearing-impaired populations.Listening effort can be reliably measured and validated in Kannada-speaking adults through behavioural paradigms like the WIRT and self-reported measures like the EEAS, enabling improved clinical assessment of listening effort in hearing-impaired individuals.
