Summary
Acoustic analysis effectively assesses hoarseness, with Noise-to-Noise Excitation (NNE) and Signal-to-Noise Ratio (SNR) being key indicators. This objective method aids in clinical evaluation of voice disorders.
Area of Science:
- Speech-language pathology
- Acoustic phonetics
- Otolaryngology
Context:
- Hoarseness is a common voice disorder affecting vocal quality.
- Accurate assessment is crucial for diagnosis and treatment planning.
- Traditional auditory assessment can be subjective.
Purpose:
- To explore the correlation between objective acoustic analysis and subjective auditory assessment of hoarseness.
- To identify key acoustic parameters that best describe hoarseness severity.
Summary:
- Acoustic analysis was performed on 24 normal and 154 pathological voice samples, categorized into four hoarseness groups.
- Significant differences in acoustic parameters were observed across groups, except for jitter between normal and mild hoarseness.
- Noise-to-Noise Excitation (NNE) and Signal-to-Noise Ratio (SNR) emerged as primary descriptors of hoarseness.
- A strong correlation was found between five acoustic parameters and auditory hoarseness assessment.
Impact:
- Acoustic analysis provides an objective and straightforward method for clinical hoarseness assessment.
- This technique can enhance diagnostic accuracy and treatment efficacy for voice disorders.
- Findings support the integration of acoustic analysis into routine clinical practice.
