IRCT20181203041834N1 IRCT 2019-10-14 Iran University of Medical Sciences effect of combined active and passive listening tasks on simultaneous sound segregation exploring the effect of auditory training regimes with combined active listening and passive hearing on perceptual learning caused by double vowel recognition exercises 2019-01-21 anticipated 32 Complete https://irct.ir/trial/35770 interventional Randomization: Not randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Factorial, Purpose: Supportive. N/A the effect of auditory training on perception of speech in noisy environment in healthy subjects. Intervention 1: Intervention group: active listening group who receive active listening trainings on double vowel recognition via computer for five days. each training section will last 90 minutes during which participants listen to double vowel stimuli with different amount of f0 separation (f0 difference decreases after each correct response). Intervention 2: Intervention group: active listening and passive hearing group who receive active listening and passive hearing training on double vowel recognition for five days. each training section will last 90 minutes. during active listening period of training participants listen to double vowel stimuli with different amount of f0 separation and try to recognize the two of the vowels (f0 difference decreases after each correct response). During passive hearing period of the training participants will play a video game (TETRIS) while double vowel stimuli will be heard passively via earphones. Intervention 3: Intervention group: passive hearing group who are going to hear double vowel stimuli passively while playing a video game (TETRIS). This intervention will last for five days, 90 minutes each session. Double vowel stimuli will be presented via headphones and their F0s may varry from 0 to 5 semitones. Participants will be told not to pay attention to the auditory stimuli during playing TETRIS. Intervention 4: Control group: participants of control group will recieve no double-vowel-training intervention between EEG recording sessions. No - There is not a plan to make this available Justification or reason for not sharing IPD is because of small amplitude of ORN wave it can not be measured individually so a grand average will be provided and reported.
