Hearing in Noise Test Brazil: standardization for youngadults with normal hearing
Individuals with the same ability of speech recognition in quiet can haveextremely different results in noisy environments.Objective: To standardize speech perception in adults with normal hearing in the free fieldusing the Brazilian Hearing in Noise Test.Methods: Contemporary, cross-sectional cohort study. 79 adults with normal hearing and with-out cognitive impairment participated in the study. Lists of Hearing in Noise Test sentenceswere randomly in quiet, noise front, noise right, and noise left.Results: There were no significant differences between right and left ears at all frequenciestested (paired t − 1 test). Nor were significant differences observed when comparing gender andinteraction between these conditions. A difference was observed among the free field positionstested, except in the situations of noise right and noise left.Conclusion: Results of speech perception in adults with normal hearing in the free field duringdifferent listening situations in noise indicated poorer performance during the condition withnoise and speech in front, i.e., 0◦/0◦. The values found in the standardization of the Hearingin Noise Test free field can be used as a reference in the development of protocols for
