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

The study focuses on the effect of auditory target tracking training on selective attention 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 trials,the validity of training method was verified by speech-shaped noise perception under the condition of 3 x 5 noise which is composed of two factors,the type of speech interference and the signal-to-noise ratio(SNR).The experimental results show that the speech perception performance of the training group is significantly better than that of the control group,which proves that the speech perception performance and auditory attention in speechshaped noise environment can be improved through the training of auditory target tracking.This indicates that the auditory target tracking training can stabilize the auditory attention level under the condition of speech-shaped noise.The work provides an effective method for promoting auditory selective attention in the real world and can be extended to specialized vocational training.
