Purpose: to investigate the findings of the test Masking Level Difference with the results of acoustic reflex and the composition of the phonological system of children with Phonological Disorder, with the purpose of check if there associations that may assist in understanding the process of acquisition of atypical language Methods: quantitative, observational and descriptive study, developed through secondary survey of a database, consisting of speech therapy evaluations of 110 children with Phonological Disorder, ages between 5 and 10 years. For the composition of the corpus used in this study was the requirement to have done tympanometry with present tympanogram of type A (Jerger) and have evaluation of Masking Level Difference. Results: data from 110 children, 57 were suited to these requirements, composing the population of this study, 42 male and 15 female. Of the 57 children, 23 (40.3%) had normal results of Masking Level Difference and 34 (59.7%) had altered result. No statistical difference was found in the relationship between the Masking Level Difference with the variables age, sex, degree of speech intelligibility, and the result of contralateral and ipsilateral acoustic reflex. The relationship between phonological acquisition of the phonemes in initial and medial onset, statistical significance was found between the non-acquisition of phonemes /s/ and /r/ early-onset and /s/ and /z/ in medial onset with the test result altered. Conclusion: other auditory processing abilities beyond the binaural interaction, should be studied in order to identify its relation with phonological disorder.

Metodos: estudo quantitativo, observacional e descritivo, desenvolvido por meio de levantamento secundario de um banco de dados, constituido de avaliacoes fonoaudiologicas de 110 criancas com transtorno fonologico, com idades entre 5 e 10 anos. Para a composicao do corpus deste estudo o requisito utilizado foi a realizacao da timpanometria, com curva timpanometrica do tipo A (Jerger) e possuir avaliacao do Masking Level Difference. Resultados: dos dados de 110 criancas, 57 se enquadraram nestes r
