Improving hearing aid performance in noise: Challenges and strategies
34 The Hearing Journal Improving hearing aid performance in noise April 2002 • Vol. 55 • No. 4 A common problem for people with a hearing impairment is the increased difficulty they encounter in communicating in noisy situations.1 Because the majority of people with a hearing impairment need to communicate in noisy situations at least some of the time,2 it is obvious that one design goal for he...
متن کاملMulti-microphone noise cancellation for improvement of hearing aid performance
A scheme for binaural pre-processing of speech signals for input to a standard linear hearing aid has been investigated. The system is based on that of Toner & Campbell [l] who applied the Least Mean Squares (LMS) algorithm in sub-bands to speech signals from various acoustic environments and signal to noise ratios (SNR). The processing scheme attempts to take advantage of the multiple inputs t...
متن کاملWorking 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...
متن کاملIntelligibility ratings of continuous discourse: application to hearing aid selection.
Twelve normal-hearing subjects rated the intelligibility of 35-s, hearing-aid-processed continuous discourse (CD) passages. Three talkers (two male, one female), four hearing aids, and two signal-to-babble (S/B) ratios were used in a completely crossed design. Research questions concerned: (1) ability of listeners to rate intelligibility, (2) sensitivity of hearing aid rankings were based on in...
متن کاملThe 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...
