Cognitive Spare Capacity and Speech Communication: A Narrative Overview

Cognitive Spare Capacity and Speech Communication: A Narrative Overview

Background noise can make speech communication tiring and cognitively taxing, especially for individuals with hearing impairment. It is now well established that better working memory capacity is associated with better ability to understand speech under adverse conditions as well as better ability to benefit from the advanced signal processing in modern hearing aids. Recent work has shown that ...

Cognitive Spare Capacity as a Window on Hearing Aid Benefit

Testing Listening Effort for Speech Comprehension Using the Individuals’ Cognitive Spare Capacity

Most hearing aid fittings today are almost solely based on the patient's audiogram. Although the loss of gain in the cochlea is important , for a more optimal fitting, more individual parameters of the patient's cochlear loss together with the patient's cognitive abilities to process the auditory signal are required (Stenfelt & Rönnberg, 2009; Edwards, 2007). Moreover, the evaluation of the fit...

Cognitive spare capacity in older adults with hearing loss

Individual differences in working memory capacity (WMC) are associated with speech recognition in adverse conditions, reflecting the need to maintain and process speech fragments until lexical access can be achieved. When working memory resources are engaged in unlocking the lexicon, there is less Cognitive Spare Capacity (CSC) available for higher level processing of speech. CSC is essential f...

Utilization based Spare Capacity Distribution

Flexible real-time applications have predefined temporal limits within which they can operate. Real-time systems that support flexible scheduling need a mechanism to distribute spare capacity in a predictable way among the running applications with respect to the applications’ temporal limits and available system resources. This paper introduces a greedy algorithm for spare capacity distributio...
