Evaluation of Visual Feedback for fo and SPL in Subglottal Pressure Measurements—A Methodological Study

Year: 2025

Type: article

Abstract: OBJECTIVE: and SPL in subglottal pressure measurements in habitual voice and at phonation threshold level with a syllable string and a phrase for the purpose of improving the reliability of subglottal pressure measurements. METHODS: and SPL versus no visual feedback. Two raters analyzed the pressure data for calculations of intra- and interrater reliability and found in general high agreement (Intra-rater agreement between 96% and 98% for habitual voice and 91% and 88% for phonation threshold. Inter-rater agreement was 95% for habitual voice and 80% for phonation threshold.). RESULTS: without visual feedback. CONCLUSIONS: deviations but slightly deteriorated for participants with small deviations. Thus, the procedure using visual feedback has the potential to improve the reliability of subglottal pressure measurements.
