TL;DR: In this paper, an audio signal is decomposed into lower and upper sub-band and at least the noise component of the upper subband is encoded at the decoder by a decoding means which utilises a synthesised noise excitation signal and a filter to reproduce the noise components in the lower subband.

Abstract: An audio signal is decomposed into lower and upper sub-band and at least the noise component of the upper sub-band is encoded. At the decoder the audio signal is synthesised by a decoding means which utilises a synthesised noise excitation signal and a filter to reproduce the noise component in the upper sub-band.

Benefits of bilateral cochlear implants and/or hearing aids in children
TL;DR: Functional benefits from bilateral stimulation in 20 children ages 4–14 show that both groups perform similarly when speech reception thresholds are evaluated, but there appears to be benefit from wearing two devices compared with a single device that is significantly greater in the group with two CI than in the bimodal group.
Bilateral Cochlear Implants in Adults and Children
Ruth Y. Litovsky,Aaron J. Parkinson,Jennifer Arcaroli,Robert W. Peters,Jennifer Lake,Patti M. Johnstone,Gonqiang Yu +6 more
TL;DR: Results suggest that, for adults, bilateral hearing leads to better performance on the localization task, and on the speech task when the noise is near the poorer of the 2 ears, and for children, localization and discrimination are slightly better under bilateral conditions.

Speech intelligibility and spatial release from masking in young children.
TL;DR: The findings suggest that, similar to adults, young children are able to utilize spatial and/or head shadow cues to segregate sounds in noisy environments.

TL;DR: In this paper, a common narrow-band speech signal is expanded into a wide-band signal and the expanded signal gives the impression of a wide band speech signal regardless of what type of vocoder is used in a receiver.
