Diabetes Mellitus (DM) consists of a chronic metabolic disorder of diverse origin that emerges when the pancreas stops producing enough insulin, or even when the body loses the ability to make use of this hormone efficiently. DM is considered one of the most important risk factors for the emergence of micro and macrovascular complications such as retinopathy, nephropathy, neuropathy, hypertension, and cardiovascular and neurological symptoms such as tinnitus, vertigo, and hearing loss. From some studies, it was found that histopathological changes in diabetic patients, alter the functioning of the inner ear, affecting the cochlea (modiolus, spiral lamina, organ of Corti, stria vascularis, spiral ligament, external spiral sulcus, endolymph, and perilymph), spiral ganglion, cochlear nerve, and causing even central auditory disorders. Thus, metabolic disorders resulting from diabetes mellitus can eventually jeopardize the auditory system, whose integrity is essential for speech perception to happen properly, especially in adverse listening environments, such as in environments where listening is impaired by the presence of noise. Tests of sentence recognition in quiet and noise are a valuable and indispensable tool in audiological evaluation since they enable an analysis of auditory skills in a context that is closer to everyday listening experiences. The test Portuguese Sentence List (LSP), a precursor in Brazil was prepared to understand and solve problems involving speech intelligibility, especially in noise. This test allows measuring the skills of speech recognition of a listener, as a reflection of their performance in realistic listening situations. The aim of this study is to evaluate speech recognition in noise for individuals with type I Diabetes Mellitus.(AU)
