UNLABELLED
In audiology clinics, complaints about difficulties in speech recognition in noise environments are frequent, even for normal-hearing individuals. Thus, the audiologist must not only identify a hearing loss, but also analyze speech recognition, under noisy conditions similar to those found in our daily lives.
AIM
Determine the reference value for the recognition of phrases under noisy conditions, in the free field, for adult normal hearing patients.
MATERIALS AND METHODS
This study was carried out in 2005 and 2006. We had 150 adult normal hearing individuals participating, with ages between 18 and 64 years, assessed in a sound-proof booth. We evaluation was based on lists of phrases in Portuguese. The phrases lists were presented in the free field, in the presence of a competitive noise, at the fixed intensity of 65 dB H. The incidence angle of both stimuli was 0 masculine- 0 masculine azimuth.
RESULTS AND CONCLUSION
The phrases recognition thresholds in the free fields were obtained in the signal to noise ratio of -8.14 dB H, which is the reference value for normal hearing individuals.
未标注
在听力诊所，即使是听力正常的人，也经常抱怨在嘈杂环境中语音识别困难。因此，听力学家不仅要识别听力损失，还要在类似于我们日常生活中的嘈杂条件下分析语音识别。
目的
确定成年听力正常患者在自由声场嘈杂条件下短语识别的参考值。
材料与方法
本研究于2005年和2006年进行。我们有150名年龄在18至64岁之间的成年听力正常个体参与，在隔音室进行评估。评估基于葡萄牙语短语列表。短语列表在自由声场中呈现，同时存在竞争性噪声，固定强度为65 dB H。两种刺激的入射角均为0度方位角。
结果与结论
在自由声场中，短语识别阈值在信噪比为-8.14 dB H时获得，这是听力正常个体的参考值。
