Purpose: to investigate the relation between socioeconomic classification and perceived quality of life of people who have a relative with hearing loss. Methods: it is a quantitative and descriptive exploratory research developed with relatives of hearing impaired children and teenagers, users of Sistema Único de Saúde. The researchers applied Brazil Economic Classification Criteria, and Quality of Life WHOQOL-BREF surveys. All data were tabulated and statistically analyzed using the descriptive statistics and graphical analysis of the variables. Results: twenty relatives of hearing impaired patients took part in the research. When the responses for the Brazil Economic Classification Criteria survey were descriptively analyzed, it was found that most of the participants belong to the B2 and C1 classes, corresponding to 35% each. The smaller part of the sample is in the C2 class, corresponding to 10%, and 20% are in the B1 class. It was perceived a better quality of life in the social field (69.1) and a worse quality of life in the environmental field (55.1). Conclusion: the study showed that there was a relation between families' socioeconomic classification and perceived quality of life, because the lower the socioeconomic classification, the worse was the perceived quality of life in all areas except for the environmental field.

The LS CE-Chirp stimulus was shown to be as efficient as the click to capture ABR at high levels of stimulation, with the advantage of producing greater-amplitude V waves.

A higher rate of low birth weight, and prematurity was observed in infants who underwent screening and had an audiological diagnosis by the third month of life. Only one newborn presented a change in audiological status. The authors emphasize the importance of auditory monitoring for all infants, considering this as a high-risk sample for hearing loss.
