Effect of Auditory Distractors on Speech Recognition and Listening Effort.

The study included only 16 young-adult listeners, and one was excluded because of hearing loss, so it does not show how children or adults with hearing loss respond to distractors. The distractors were always presented before the target word, and the exact jitter timing was not recorded, so the study cannot say how timing between distractor and target affected responses. The noise condition was set at +5 dB signal-to-noise ratio to keep recognition high, which may have been too easy to test whether high perceptual load reduces distraction effects on listening effort. The word lists were not balanced for word length or other word features, which could add variability to response times. The target words were chosen from a child vocabulary corpus, so young adults may not have used these words as naturally as children would. The exploratory response-time distribution analysis did not fully match the traditional median analysis, so the effort findings need replication.

The authors reported no real or perceived conflicts of interest.

Do not conclude that background noise protects listeners from distraction. Distractors did not lower word recognition in noise, but they still slowed spoken responses, and noise itself reduced word recognition.
