| Summary, etc | Understanding speech in background noise is often more difficult for individuals who are older and have<br/>hearing impairment than for younger, normal-hearing individuals. In fact, speech-understanding abilities<br/>among older individuals with hearing impairment varies greatly. Researchers have hypothesized that<br/>some of that variability can be explained by how the brain encodes speech signals in the presence of<br/>noise, and that brain measures may be useful for predicting behavioral performance in difficult-to-test<br/>patients. In a series of experiments, we have explored the effects of age and hearing impairment in<br/>both brain and behavioral domains with the goal of using brain measures to improve our understanding<br/>of speech-in-noise difficulties. The behavioral measures examined showed effect sizes for hearing<br/>impairment that were 6e10 dB larger than the effects of age when tested in steady-state noise, whereas<br/>electrophysiological age effects were similar in magnitude to those of hearing impairment. Both age and<br/>hearing status influence neural responses to speech as well as speech understanding in background<br/>noise. These effects can in turn be modulated by other factors, such as the characteristics of the background<br/>noise itself. Finally, the use of electrophysiology to predict performance on receptive speech-innoise<br/>tasks holds promise, demonstrating root-mean-square prediction errors as small as 1e2 dB. An<br/>important next step in this field of inquiry is to sample the aging and hearing impairment variables<br/>continuously (rather than categorically) e across the whole lifespan and audiogram e to improve effect<br/>estimates. |
