Purpose: The objectives of the current study are as follows: 1) to compare speech-in-noise perception performance among mild cognitive impairment (MCI) subgroups and a cognitively normal elderly (CNE) group; and 2) to explore cognitive domains specifically related to speech-in-noise perception. Methods: Data were collected on samples of 46 patients with MCI and 39 hearing threshold-matched CNE subjects. Two different patient classifications were used: 1) patients with amnestic MCI (aMCI) (n=21) or patients with non-amnestic MCI (naMCI) (n=25); and 2) patients with frontal-executive dysfunction (FED) (n=16) or patients without FED (n=30). All subjects received audiometric, neuropsychological, and speech-in-noise perception assessments. Speech-in-noise perception was measured via sentence recognition tests with speech-spectrum and multi-talker babble background noise at four SNRs: +5 dB, 0 dB, -2 dB, and -5 dB. Results: First, the MCI with FED group scored lower than both the MCI without FED and the CNE groups under both types of noise when the SNR fell from 0 dB to -5 dB. At SNR + 5 dB, there was no group difference in the presence of speech-spectrum noise, but the MCI with FED group still scored lower than the CNE group in the presence of multi-talker babble noise. Second, there were no differences between the aMCI and naMCI groups in speech perception performance under any noisy conditions. Third, significant positive correlations were found between speech-in-noise perception and frontal-executive function in the MCI patients. Conclusions: Our findings suggest that frontal-executive function strongly relates to speech-in-noise perception. Considering that deficits in speech-in-noise perception are related to increased risk of cognitive decline and dementia, MCI patients with FED who have severely impaired speech perception may have a higher risk of developing dementia. These patients should receive cognitive training focused on frontal-executive function and audiological rehabilitation.
