Portable automated rapid testing: Validation of automated testing on older listeners from India

Abstract

Portable automated rapid testing (PART) is an iPad application (https://braingamecenter.ucr.edu/games/p-a-r-t/) capable of measuring various psychoacoustic thresholds in an automated and rapid format using commercially available headphones. The app has been validated previously in native speakers of English and an adapted version of the app has been validated in young normal hearing listeners from Mexico. Previous research from our labs indicated that the thresholds obtained using non-speech tasks did not differ significantly between the native and the non-native speakers of English while the native speakers of English had significantly better thresholds in the speech task. However, there was no significant difference in the amount of spatial release from masking between the groups. Here, we present psychoacoustic threshold data for a large cohort of older listeners from India with various English proficiencies. The thresholds obtained from this group will be compared against previously published thresholds based on native speakers of English. It is hypothesized that the results would be similar to what was found earlier with younger listeners from India. These results will give us the evidence to start using this app to measure thresholds of various central auditory processing measures in non-native speakers of English.
