What is harmonic ratio?

The harmonic ratio measures the amount of energy in the tonal part of the signal compared to the amount of energy in the total signal.

How do you calculate harmonics-to-noise ratio?

A Harmonicity object represents the degree of acoustic periodicity, also called Harmonics-to-Noise Ratio (HNR). Harmonicity is expressed in dB: if 99% of the energy of the signal is in the periodic part, and 1% is noise, the HNR is 10*log10(99/1) = 20 dB.

What does high harmonic to noise ratio mean?

The Harmonics-to-Noise (HNR) ratio is a measure of the proportion of harmonic sound to noise in the voice measured in decibels. (Ferrand, 2007). HNR quantifies the relative amount of additive noise (Awen & Frankel, 1994) The lower the HNR, the more noise in the voice.
