This work was supported in part by the ASHFoundation Student Audiology Research Grant awarded to L.C. and the Jerome R. and Arlene L. Gerber Fund. The authors would like to thank Dr. Brent Edwards and Dr. Tim Trine at Starkey Corporation for providing the hearing aids used for testing. These data have also been published by L.C. as part of her requirement for her dissertation at Syracuse University. Many thanks to Dr. Laurel Carney, Dr. Kathy Vander Werff, and especially Dr. Larry Humes for helpful comments while writing this manuscript. Comments from three anonymous reviewers and Dr. Paul Iverson, the associate editor, have tremendously strengthened this manuscript.

N2 - Spectral weighting strategies using a correlational method [R. A. Lutfi, J. Acoust. Soc. Am. 97, 1333-1334 (1995); V. M. Richards and S. Zhu, J. Acoust. Soc. Am. 95, 423-424 (1994)] were measured in ten listeners with sensorineural-hearing loss on a sentence recognition task. Sentences and a spectrally matched noise were filtered into five separate adjacent spectral bands and presented to listeners at various signal-to-noise ratios (SNRs). Five point-biserial correlations were computed between the listeners' response (correct or incorrect) on the task and the SNR in each band. The stronger the correlation between performance and SNR, the greater that given band was weighted by the listener. Listeners were tested with and without hearing aids on. All listeners were experienced hearing aid users. Results indicated that the highest spectral band (∼2800-11 000 Hz) received the greatest weight in both listening conditions. However, the weight on the highest spectral band was less when listeners performed the task with their hearing aids on in comparison to when listening without hearing aids. No direct relationship was observed between the listeners' weights and the sensation level within a given band.
