Abstract

Most children with Down syndrome has high rates of middle ear disorders, most of the times leading to conductive hearing loss (Soares, 2013). In this study, measures of broadband acoustic absorbance will be used to evaluate the middle ears of the subjects, since the characteristics of broadband acoustic impedance measures are directly related to middle ear condition (Araújo, 2015). The absorbance, is the ratio between the energy absorbed by the middle ear and the incident energy presented in the ear canal (Carrico et al, 2014). This evaluation technique of the middle ear has some advantages, such as covering a wide frequency range, not having such critical position of the probe in the ear canal (especially at high frequencies) and not requiring pressurization of the ear canal. It requires little time to do a full scan of the absorbance in a wide frequency range and can be a very sensitive test in the evaluation of middle ear disorders and conductive hearing loss (Silva et al, 2013). Objective: To analyze the acoustic absorbance measured with broadband stimuli in ambient pressure in children with DS. Method: This is a prospective, cross-sectional analytical study. In this research, will participate 15 children with DS, between 6 and 10 years (study group), and 15 children of the same age without SD, with no hearing and no hearing risk indicators (control group).
