INTRODUCTION
Individuals with the same ability of speech recognition in quiet can have extremely different results in noisy environments.
OBJECTIVE
To standardize speech perception in adults with normal hearing in the free field using the Brazilian Hearing in Noise Test.
METHODS
Contemporary, cross-sectional cohort study. 79 adults with normal hearing and without cognitive impairment participated in the study. Lists of Hearing in Noise Test sentences were randomly in quiet, noise front, noise right, and noise left.
RESULTS
There were no significant differences between right and left ears at all frequencies tested (paired t-1 test). Nor were significant differences observed when comparing gender and interaction between these conditions. A difference was observed among the free field positions tested, except in the situations of noise right and noise left.
CONCLUSION
Results of speech perception in adults with normal hearing in the free field during different listening situations in noise indicated poorer performance during the condition with noise and speech in front, i.e., 0°/0°. The values found in the standardization of the Hearing in Noise Test free field can be used as a reference in the development of protocols for tests of speech perception in noise, and for monitoring individuals with hearing impairment.
引言
在安静环境中具有相同言语识别能力的个体，在嘈杂环境中的结果可能截然不同。
目的
使用巴西噪声环境下听力测试对正常听力的成年人在自由声场中的言语感知进行标准化。
方法
当代横断面队列研究。79名听力正常且无认知障碍的成年人参与了该研究。噪声环境下听力测试句子列表在安静、噪声在前、噪声在右和噪声在左的环境中随机呈现。
结果
在所有测试频率下，左右耳之间均无显著差异（配对t检验）。比较性别以及这些条件之间的相互作用时，也未观察到显著差异。在所测试的自由声场位置中观察到了差异，但噪声在右和噪声在左的情况除外。
结论
正常听力的成年人在噪声环境中不同聆听情况下自由声场中的言语感知结果表明，在噪声和言语在前即0°/0°的条件下表现较差。噪声环境下听力测试自由声场标准化中得到的值可作为制定噪声环境中言语感知测试方案以及监测听力障碍个体的参考。
