App Summary

Listen - Auditory Training is a gamified program that uses principles of perceptual learning to train auditory processing skills, such as sound localization and working memory, to improve speech comprehension in noisy environments. The associated research (N=30) in normally hearing adults found this mixed-training approach led to modest improvements on speech-in-competition tests compared to an active control condition (Cohen's d = 0.68). The authors conclude that these initial data show promise for future study in populations with hearing difficulties.

Detailed Description

Functionality & Mechanism

Developed at the University of California Riverside's Brain Game Center, this system leverages perceptual learning and auditory neuroscience within a gamified interface. Sessions require responding to discrete sound cues, based on language primitives, to navigate in-game obstacles. The platform integrates adaptive algorithms that continuously measure auditory discrimination ability and calibrate task difficulty to each individual's performance threshold. This mechanism is designed to progressively enhance spectral-temporal processing, sound localization, and auditory working memory through repeated engagement.

Evidence & Research Context

  • A comparative study (N=30) evaluated the system's training protocol in college-aged participants with normal hearing.
  • The protocol demonstrated modest improvements in understanding speech in competition compared to an active control condition (Cohen's d = 0.68).
  • The training modules are designed to target a mixture of foundational auditory processing skills believed to underlie speech comprehension in noisy environments.
  • The associated research notes the preliminary nature of these findings and suggests the need for future investigation in populations with hearing difficulties.

Intended Use & Scope

This auditory training system is designed as a research tool for investigating perceptual learning and as a cognitive fitness application for the general public. Its primary utility is to provide structured training on specific auditory processing skills. The application is not a diagnostic tool or a substitute for professional audiological evaluation or prescribed hearing loss interventions.

Effectiveness/Outcome Study

Training with an auditory perceptual learning game transfers to speech in competition

Polley et al. (2021) · NPJ Science of Learning

Showed modest improvement in understanding speech with background noise but results were based on small sample.

Understanding speech in the presence of acoustical competition is a major complaint of those with hearing difficulties. Here, a novel perceptual learning game was tested for its effectiveness in reducing difficulties with hearing speech in competition. The game was designed to train a mixture of auditory processing skills thought to underlie speech in competition, such as spectral-temporal processing, sound localization, and auditory working memory. Training on these skills occurred both in quiet and in competition with noise. Thirty college-aged participants without any known hearing difficulties were assigned either to this mixed-training condition or an active control consisting of frequency discrimination training within the same gamified setting. To assess training effectiveness, tests of speech in competition (primary outcome), as well as basic supra-threshold auditory processing and cognitive processing abilities (secondary outcomes) were administered before and after training. Results suggest modest improvements on speech in competition tests in the mixed-training compared to the frequency-discrimination control condition (Cohen's d?=?0.68). While the sample is small, and in normally hearing individuals, these data suggest promise of future study in populations with hearing difficulties.
