IRCT20190118042404N1 IRCT 2019-02-25 Iran University of Medical Sciences The effects of spatial auditory training on speech in noise perception in elderly The effects of “ auditory spatial training” on informational masking release with persian version of coordinate response measure(CRM) in elderly normal hearing listeners 2019-02-19 anticipated 30 Complete https://irct.ir/trial/36954 interventional Randomization: Not randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Single, Purpose: Supportive. N/A central auditory processing disorder and speech in noise perception problem. Intervention 1: Intervention group: The people with even numbers will participate in this group. Rehabilitation sessions will be divided into some main categories: sessions with nonmeaningful competing signals such as white noise and sessions with meaningful distractive signals such as babble noise and some sentences. In all of the spatial training sessions the target signal will present from the 0 azimuth degree and the competing maskers will present from + and - 90 azimuth degree. We will use the Persian version of Quick SIN as a target signals. Every session will start from the signal to noise ratio which patient will respond correctly to less than 50 percent of sentences and will continue until 30 minutes. Training sessions will continue for 6 weeks and every week patient will participated in two sessions. Intervention 2: Control group: The persons with odd numbers will be in the control group. These people must not recieve any rehabilitative programs during this study. All of the particapated persons of our study are suffering from speech in noise perception, so we will guarantee that if our designed spatial traing has a significant value on the speech in noise perception we will administrate that to all of the control group persons.
