Cognition and hearing aids.
TLDR
It is argued that signal processing designed to improve speech understanding may have both positive and negative consequences, and that these may depend on individual WM capacity.Abstract:
The perceptual information transmitted from a damaged cochlea to the brain is more poorly specified than information from an intact cochlea and requires more processing in working memory before language content can be decoded. In addition to making sounds audible, current hearing aids include several technologies that are intended to facilitate language understanding for persons with hearing impairment in challenging listening situations. These include directional microphones, noise reduction, and fast-acting amplitude compression systems. However, the processed signal itself may challenge listening to the extent that with specific types of technology, and in certain listening situations, individual differences in cognitive processing resources may determine listening success. Here, current and developing digital hearing aid signal processing schemes are reviewed in the light of individual working memory (WM) differences. It is argued that signal processing designed to improve speech understanding may have both positive and negative consequences, and that these may depend on individual WM capacity.read more

Cognitive Load During Speech Perception in Noise: The Influence of Age, Hearing Loss, and Cognition on the Pupil Response
TL;DR: Ageing and hearing loss were related to less release from effort when increasing the intelligibility of speech in noise and this indicates that utilizing linguistic ability to improve speech perception is associated with increased listening load.

The emergence of cognitive hearing science.
TL;DR: Cognitive Hearing Science is illustrated in research on three general topics: (1) language processing in challenging listening conditions; (2) use of auditory communication technologies or the visual modality to boost performance; (3) changes in performance with development, aging, and rehabilitative training.

Effects of noise and working memory capacity on memory processing of speech for hearing-aid users
TL;DR: Noise reduction can reduce the adverse effect of noise on memory for speech for persons with good working memory capacity and it is argued that the mechanism behind this is faster word identification that enhances encoding into working memory.
Journal ArticleDOI
Working memory supports listening in noise for persons with hearing impairment.
TL;DR: The finding of superior performance of persons with high working memory capacity in modulated noise with fast-acting compression agrees with findings of previous studies including a familiarization period of at least 9 wk, in contrast to studies with familiarization of 4 wk or less that have shown that persons with lower cognitive capacity may benefit from slow- acting compression.

The episodic buffer: a new component of working memory?
TL;DR: The revised model differs from the old principally in focussing attention on the processes of integrating information, rather than on the isolation of the subsystems, which provides a better basis for tackling the more complex aspects of executive control in working memory.

The magical number 4 in short-term memory: a reconsideration of mental storage capacity.
TL;DR: A wide variety of data on capacity limits suggesting that the smaller capacity limit in short-term memory tasks is real is brought together and a capacity limit for the focus of attention is proposed.
Journal ArticleDOI
A capacity theory of comprehension: individual differences in working memory.
TL;DR: A theory of the way working memory capacity constrains comprehension is proposed, which proposes that both processing and storage are mediated by activation and that the total amount of activation available in working memory varies among individuals.

Speech enhancement using a minimum-mean square error short-time spectral amplitude estimator
Yariv Ephraim,David Malah +1 more
TL;DR: In this article, a system which utilizes a minimum mean square error (MMSE) estimator is proposed and then compared with other widely used systems which are based on Wiener filtering and the "spectral subtraction" algorithm.

Speech enhancement using a minimum mean square error short-time spectral amplitude estimator
TL;DR: This paper derives a minimum mean-square error STSA estimator, based on modeling speech and noise spectral components as statistically independent Gaussian random variables, which results in a significant reduction of the noise, and provides enhanced speech with colorless residual noise.
