Brain aging and speech perception in noise: effects of background noise and talker variability

In Experiment 2, we examined the relationship between speech perception in noise and brain structure and function using magnetic resonance imaging (MRI) in a subset of 32 participants from Experiment 1. The project was approved by the Comité d’éthique de la recherche sectoriel en neurosciences et santé mentale, Institut Universitaire en Santé Mentale de Québec (#360-2014). Here we share all stimulus files, stimulus information and experiment files for both experiments.

We also share uncorrected and corrected group MRI data (average brain, functional and structural MRI group maps). Individual data (behavioural and MRI), cannot be shared because participants did not consent to individual data sharing. To be meaningful, the behavioural data would need to contain information such as age, sex, etc. and such information could lead to the identification of the participants.

The study is published in the open access journal Neuroimage: Tremblay, P., Brisson, V., Deschamps, I. (2020). Brain aging and speech perception in noise: effects of background noise and talker variability. Neuroimage, 227, 117675. doi.org/10.1016/j.neuroimage.2020.117675
