Efficacy of auditory target tracking training to enhance selective attention during continuous speech-shaped noise

Auditory training may strengthen auditory skills that help human not only in on-task auditory perception performance but in continuous speech-shaped noise environment.Firstly,a short-term and simplified training method was designed which adopted stable stimuli tracking to train the participants.After twenty training units,the validity of training method was verified by speech-in-noise perception under the 3×5 noise composed of two factors:types of interference speech and the signal-to-noise ratio.As a result,the training group presented significant better speech perception performance than control group.Outcome suggest that efficacy of auditory target tracking training can improve speech perception performance and selective attention during speech-shaped noise environment.These findings provide an effective method to promote auditory selective attention in real-world,and extended to special vocational training.
