What does the Noise: Harmonics Ratio assess in acoustic measurements?

The Noise: Harmonics Ratio is a valuable assessment in acoustic measurements that specifically evaluates the quality of harmonics in vocal sound. This ratio provides insight into how much harmonic content is present in a voice relative to the noise or breathiness that may accompany it. A higher ratio indicates a clearer and richer harmonic structure, which is often associated with a more pleasant vocal quality. Understanding this ratio is critical in various fields, such as speech-language pathology and music, as it helps professionals gauge the overall health and quality of a person's voice and can assist in identifying potential vocal disorders.
