There are 9 (35,8%) female and 14 (64,2%) male preschool cochlear implant users in the study group.

Children ranging in age from 5 to 7 who also have 5-6 years old language skills.

There are 9 (35.8%) female and 14 (64,2%) male preschool children with normal hearing in the control group.

Children ranging in age from 5 to 6 who also have age-appropriate language skills.

We would like to observe the effect of the music integrated phonological awareness program on preschool cochlear implant users and to compare the phonological awareness skills of the study group with the control group before and after the online training. The program is prepared as 10 lessons. Participants were guided through online training for 5 weeks, with 20-minute sessions conducted weekly. The training was carried out via Zoom, a free virtual interview program. Each family had a computer.

The Early Childhood Phonological Awareness Scale (PASECP) was used to measure sound awareness and sound discrimination skills of preschool children whose language age is between 60-72 months. The test has 8 sub-dimensions. There are 8 test items in the first sub-dimension and 10 test items in the other sub-dimensions, with a total of 78 test items. If the answers given by the children to the scale items are correct (1), if incorrect (0), they are coded into the answer key. The test is administered to children individually. The application time for each child takes approximately 15 minutes. High scores of the child indicate that his/her phonological awareness is good.

Mismatch Negativity (MMN) was used to evaluate the central auditory system. Neuron-Spectrum-5 (4/EPM) (Neurosoft, Ivanoco, Russia) was used for the electrophysiological recordings of the study group. Speech stimuli were used as stimuli. Amplitude and latency changes were observed in the Mismatch Negativity test before and after the training. The increase in amplitudes and shortening of latencies after training indicate that the central auditory system has developed.

Spectral-Temporally Modulated Ripple Test (SMRT) was used to assess the spectral discrimination ability of the study group. The test was performed using SMRT software. Waveform broadband noise with spectral-temporal modulation was used. In each trial, three ripple sounds were presented. Two stimuli were reference signals with an intensity of 20 ripple/octave (rpo) and another stimulus was a target signal with a lower rpo intensity. The initial intensity of the target signal was 0.5 rpo and was replaced by a step size of 0.2 rpo. Adaptive running terminated after ten reverses.Spectral-Temporally Modulated Ripple Test was calculated over the last six reversals. Three runs were completed for each child, and the final threshold was determined by averaging the three runs. Having a low rpo value was an indication of good spectral resolution of the children.
