Portable automated rapid testing of central auditory processing measures implemented in the app PART (https://braingamecenter.ucr.edu/games/p-a-r-t/) were adapted for Spanish-speaking populations. This adaptation included the generation of a corpus equivalent to the CRM to test a speech-on-speech masking task, in addition to frequency modulation tasks, temporal gap, temporal, spectral and spectro-temporal modulations, and pure tone detection in noise. This battery of tests was selected for its potential clinical utility and its previous validation across several settings including remote testing with participant-owned headphones, tablets or smartphones. Here, we tested 96 young adults in Mexico City (ages 18–45) with normal hearing. As expected, distributions of scores were similar to previously reported norms for the English-language version of the battery in English-speaking populations. Scores for the newly developed Spanish-language speech-on-speech masking tests were also similar to data previously reported in English-speaking populations. Furthermore, there was no significant effects of age or subjective hearing handicap (HHIA) in any of the tests. This study can be now used as a normative dataset, and the adapted battery can be used as an accsessible tool (available freely online) for valid and reliable testing of central auditory processing measures in Spanish-language populations.
