Abstract
This study aims to determine the degree to which Portable Automated Rapid Testing (PART), a freely available program running on a tablet computer, is capable of reproducing standard laboratory results. Undergraduate students were assigned to one of three within-subject conditions that examined repeatability of performance on a battery of psychoacoustical tests of temporal fine structure processing, spectro-temporal amplitude modulation, and targets in competition. The repeatability condition examined test/retest with the same system, the headphones condition examined the effects of varying headphones (passive and active noise-attenuating), and the noise condition examined repeatability in the presence of recorded cafeteria noise. In general, performance on the test battery showed high repeatability, even across manipulated conditions, and was similar to that reported in the literature. These data serve as validation that suprathreshold psychoacoustical tests can be made accessible to run on consumer-grade hardware and perform in less controlled settings. This dataset also provides a distribution of thresholds that can be used as a normative baseline against which auditory dysfunction can be identified in future work.

This study examined the validity and reliability of a battery of ten assessments that evaluate different aspects of the central auditory function using the PART application applied to young adult listeners without reported hearing problems
Summary
Treatment of auditory difficulties that are not accompanied by losses of audibility. The diagnostic and rehabilitative approaches that do exist are regarded as specialized tools to be used by those clinicians who work with children or adults with suspected auditory processing disorders (APDs). The screening test for auditory processing (SCAN; Keith, 1995) is a battery of assessments that incorporates multiple auditory processing abilities While these and other tests have been used successfully both in the laboratory and the clinic to identify auditory processing dysfunction (e.g., Gallun et al, 2012; Gallun et al, 2016; Hoover et al, 2017), none of them are portable, automated, or rapid. Portable automated rapid testing could play an essential role in gathering the datasets necessary to better characterize the auditory processing abilities and difficulties of individual listeners relative to the expected abilities of other listeners of a similar age with similar audiometric thresholds Without this information, the clinician will continue to have difficulty appropriately identifying and remediating the auditory processing dysfunction they observe in their patients.
