Abstract

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.
