Language delay is a deficiency in children to develop language abil- ities on the chronological age appropriate. The purpose of the study is to investigate the effects of signal to noise ratio of auditory cortical responses to expressive language delay.
This research was conducted in the Audiology Department of Istan- bul University Cerrahpasa Faculty of Medicine. 20 children whose age’s between 3-6 and diagnosed language delay were included in this study. The patients were evaluated as audiological and included participants within normal hearing limits. Auditory cortical respons- es have been tested by FRYE Hearlab ACE, receptor- expressive lan- guage skills were tested with the PLS -4 test battery. Patients; were tested in three sessions. Stimuli were sent in three ways. A) In a quiet environment, the signal intensity of 75dB SPL, B) SNR:0 (Signal:75 dB SPL, Noise:75 dBSPL, C) SNR:+10 (Signal:75 dB SPL, Noise:65 dBSPL. Results will be discussed.
