The aim of the current study is to investigate the potential use of specific metrics in assessing the quality and optimizing an individual's cochlear implant fitting. Assessment of the sensitivity and specificity of specific metrics that are potential predictors of inaccurate T-levels and C-levels is important to determining best methods for streamlined high quality fitting, as well as automated adjustments for optimizing. One of the key objectives is to integrate a new technological advance in the form of in-situ audiometry, which removes the need for a sound booth to conduct audibility checks of the program. Other planned investigations relate to identifying the metrics which best identify maps that are not optimized, and to development and assessment of a range of techniques which may be able to be effectively applied in the clinical setting.
