The Impact

Musicians have enhanced auditory processing abilities. In some studies, these abilities are paralleled by an improved understanding of speech in noisy environments, partially due to more robust encoding of speech signals in noise at the level of the brainstem. Little is known about the impact of musicianship on attention-dependent cortical activity related to lexical access during a speech-in-noise task. To address this issue, we presented musicians and nonmusicians with single words mixed with three levels of background noise, across two conditions, while monitoring electrical brain activity. In the active condition, listeners repeated the words aloud, and in the passive condition, they ignored the words and watched a silent film. When background noise was most intense, musicians repeated more words correctly compared with nonmusicians. Auditory evoked responses were attenuated and delayed with the addition of background noise. In musicians, P1 amplitude was marginally enhanced during active listening and was related to task performance in the most difficult listening condition. By comparing ERPs from the active and passive conditions, we isolated an N400 related to lexical access. The amplitude of the N400 was not influenced by the level of background noise in musicians, whereas N400 amplitude increased with the level of background noise in nonmusicians. In nonmusicians, the increase in N400 amplitude was related to a reduction in task performance. In musicians only, there was a rightward shift of the sources contributing to the N400 as the level of background noise increased. This pattern of results supports the hypothesis that encoding of speech in noise is more robust in musicians and suggests that this facilitates lexical access. Moreover, the shift in sources suggests that musicians, to a greater extent than nonmusicians, may increasingly rely on acoustic cues to understand speech in noise.

AbstractDifficulty hearing in the presence of background noise is a common complaint heard by audiologists. This can be accompanied by additional difficulty in classrooms and other difficult listening situations. This was recently exacerbated by the coronavirus disease 2019 (COVID-19) shutdowns and the accompanying mask usage and virtual meetings. This article describes one such patient seen during the recent shutdown. This patient reported difficulty hearing during her college coursework for her music performance major. She was an established otology patient with an extensive middle ear history including multiple surgeries. During the shutdown, she virtually consulted with the auditory processing disorders clinic at the recommendation of her otologist to discuss her college-related difficulty and pursue educational accommodations. Challenges and solutions for seeing this patient and other, similar patients virtually are discussed as well as a review of how this patient proceeded and how the knowledge gained from this patient could apply to others with similar concerns.
