Effects of noise and working memory capacity on memory processing of speech for hearing-aid users.

OBJECTIVES It has been shown that noise reduction algorithms can reduce the negative effects of noise on memory processing in persons with normal hearing. The objective of the present study was to investigate whether a similar effect can be obtained for persons with hearing impairment and whether such an effect is dependent on individual differences in working memory capacity. DESIGN A senten...

Working memory and intelligibility of hearing-aid processed speech

Previous work suggested that individuals with low working memory capacity may be at a disadvantage in adverse listening environments, including situations with background noise or substantial modification of the acoustic signal. This study explored the relationship between patient factors (including working memory capacity) and intelligibility and quality of modified speech for older individual...

The Relationship Between Acceptable Noise Level and Initial Acceptance of Hearing Aid

Introduction: The Acceptable Noise Level (ANL) evaluates the willingness of a listener to hear a continuous speech in the presence of background noise. ANL is related to some variables. Although many studies were accomplished on the relationship between ANL and hearing aid satisfaction, no study was found for the usage of ANL as the predictor of initial hearing aid acquisition. Therefore, the c...

Dynamic Relation Between Working Memory Capacity and Speech Recognition in Noise During the First 6 Months of Hearing Aid Use

The present study aimed to investigate the changing relationship between aided speech recognition and cognitive function during the first 6 months of hearing aid use. Twenty-seven first-time hearing aid users with symmetrical mild to moderate sensorineural hearing loss were recruited. Aided speech recognition thresholds in noise were obtained in the hearing aid fitting session as well as at 3 a...

Working Memory and Hearing Aid Processing: Literature Findings, Future Directions, and Clinical Applications

Working memory-the ability to process and store information-has been identified as an important aspect of speech perception in difficult listening environments. Working memory can be envisioned as a limited-capacity system which is engaged when an input signal cannot be readily matched to a stored representation or template. This "mismatch" is expected to occur more frequently when the signal i...
