Background & Aim

Spatial listening is the ability to distinguish a target speech stream from simultaneous distracting noise using auditory spatial awareness. It relies on several factors, including the listener’s hearing thresholds, auditory experience, familiarity with the surrounding environment, motivation, and attention.

Listening in noisy environments is especially challenging for younger children in school settings, where early educational skills are often taught amidst background noise. Spatial processing disorder (SPD) is a significant issue observed in a notable proportion of children diagnosed with auditory processing disorder (APD). This round table will explore spatial listening research work in children

Material & Methods

Psychophysical and electrophysiological measures of spatial listening were condcted on normal children to establish norms for these measures

Results

It showed normal scores of the test that improved with age in both LiSN test and electrophysiological measures

Conclusions

LiSN test is a promising tool for assessing spatial listening as well as electrophysiological measures

Keywords

Research and clinical interest in cochlear implant (CI) electrode impedance have evolved significantly throughout 2024 and 2025. The current focus has shifted from simple "functionality checks" to using impedance as a sophisticated biomarker for the internal environment of the cochlea. In CIs, electrode impedance measurement plays a role in optimizing power requirements, establishing electrode integrity, and determining electrical stimulation parameters such as the pulse duration, pulse amplitude, and stimulation rate. Any changes in impedance levels may indicate issues with the electrodes and/or cochlear implants, such as short circuits, open circuits, or damaged devices. Long-term use of the device may lead to a reduction in its efficiency in delivering electrical current to the surrounding cochlear tissues, resulting in an increase in impedance and decreased implant effectiveness. Therefore, it is saliently important to perform follow-up examinations post-implantation to investigate potential changes in the electrical impedance of cochlear implants over time. On the other hand, early activation results in decrease of impedance and better voltage transmission across electrodes. This of course will improve the outcome performance of CI. Impedance Voltage Matrix an emerging tool provide a deeper insight on the electrode neural interface at each electrode. Different electrode impedance models are developing to be integrated into clinical practice using the standard software. All detailed related updates will be highlighted in the roundtable.
