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.

Related Experiment Videos

  • 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.
