Thirteen individuals with laryngopharyngeal reflux (LPR) were studied pre- and post-treatment. The effect of treatment on perceptual ratings of voice quality and frequency and intensity measures was examined. Relationships between perceptual and acoustic parameters were assessed descriptively. Results showed a small, but significant improvement in the perception of voice quality post-treatment. No significant differences were found between pre- and post-treatment means for any of the acoustic measures except harmonics-to-noise ratio (HNR). Descriptive analyses showed some association between perceptual ratings and acoustic measures. Discussion of results focuses on severity of LPR.
对13名患有喉咽反流（LPR）的个体进行了治疗前和治疗后的研究。研究了治疗对嗓音质量的感知评分以及频率和强度测量的影响。对感知参数和声学参数之间的关系进行了描述性评估。结果显示，治疗后嗓音质量的感知有小幅但显著的改善。除谐波噪声比（HNR）外，其他声学测量的治疗前和治疗后平均值之间未发现显著差异。描述性分析显示，感知评分与声学测量之间存在一定关联。结果讨论集中在喉咽反流的严重程度上。
