This study aims to compare the scores of PEACH and TEACH in children with severe-to-profound sensorineural hearing loss (SNHL) using hearing aids. Methods: This is a double-blind two-period crossover study on 21 children aged 9-72 months with severe-to-profound SNHL using hearing aids. There were two 6-week periods of fitting Phonak Naida Venture SP hearing aids using the fifth version of the Desired Sensation Level (DSL v5) and the National Acoustics Laboratories’ nonlinear fitting procedure (NAL-NL2) prescriptions. At the end of each trial, the PEACH and TEACH questioners were completed through an interview with the parents and teachers, respectively. Results: There was a strong correlation between the PEACH and TEACH in total and subscale scores. There was no significant difference between the results of DSL v5 and the NAL-NL2 prescriptions for the total score and subscale scores of PEACH and TEACH. Conclusion: The PEACH score has a strong correlation with the TEACH score. These questionnaires are useful tools for indirectly assessment of hearing-impaired children’s communication skills. The DSL v5 and the NAL-NL2 prescriptions make no significant difference in the performance of children with severe-to-profound SNHL. https://avr.tums.ac.ir/index.php/avr/article/view/938
