Use of hearing devices and fluency in Brazilian Sign Language and oral language in deaf students

ABSTRACT Purpose: to assess the relationship between deaf students’ fluency in Brazilian Sign Language (BSL) and oral language and hearing aid use. Method: the sample comprised 112 professional BSL translators, interpreters, and instructors. They answered a questionnaire on hearing characteristics and BSL and oral language fluency of students accompanied by them, who attended municipal schools in a Brazilian city. Association analysis between oral language fluency, BSL fluency, the degree of hearing loss, and device use was made with the chi-square test or Fisher’s Exact test. The significance level was set at p<0.05. Results: the professionals’ responses referred to 88% (n = 126) of all deaf students enrolled in municipal schools. The students’ mean age was 13 years; 72 (57%) were males, 98 (78%) had severe or profound hearing loss, 57 (45%) used electronic hearing devices, 83 (66%) were fluent only in BSL, 12 (10%) were fluent only in oral language, and 18 (14%) were fluent in both BSL and oral language. Hearing device use was statistically associated with oral fluency (p < 0.001). Of all students fluent in oral language (n = 30), 18 (60%) were also fluent in BSL (p < 0.001). Conclusion: BSL was the communication modality most used by students, including those who also used oral language and electronic hearing devices. This may indicate a change in the social perception of deaf people, their language, and their culture.
