Explaining Sound: What is total harmonic distortion (THD ...
https://audiophileon.com/news/what-is-total-harmonic-distortion-thd/
Distortion is one of the biggest factors when it comes to producing the best sound possible. Distortion of a sound is exactly what it sounds like. It is extra being put into the final output signal and making it sound wrong, i.e., distorted from its pure form. Audiophiles work hard at all stages of their setup, whether it be with headphones an…

Total harmonic distortion (THD) is the sum of all the harmonics measured in the product’s output. A THD measurement sums all the distortion products by adding up the extra harmonic energy into a single value, expressed as either a percentage (which we’ll typically show on a logarithmic scale), or as a dB value, representing the proportion of the energy compared to …
Total Harmonic Distortion (THD): Is It a Good Indicator of ...

Harmonic distortion is often stated as a measurement called Total Harmonic Distortion, or THD, which is a percentage of the overall signal composed of harmonic distortion. THD is not a good indicator of how audible harmonic distortion will be unless it is of an extremely high or extremely low value. This is because there could be relatively high amounts of harmonic distortion in …

Total harmonic distortion or THD is a very important parameter in the audio amplifier domain. THD is a measure of the amount of harmonic components present in a signal. It can be defined as the ratio of the sum of the powers of all the harmonic components to the power of the fundamental frequency.
How much THD is audible? – PS Audio

THD is a measurement method that quantifies the severity of non-linear distortion in a signal processing stage, by injecting a pure sine wave test stimulus and measuring the generation of harmonics. We wouldn’t normally be listening to THD, except in the unusual case of feeding a pure sine wave to the amplifier and listening to the output.
What are GOOD THD % ratings? | AVS Forum

THD is primarily even-order harmonic distortion, measured with single test tones. Even-order harmonic distortion up to around 2% during program material is almost always inaudible. Music and movie soundtracks are more complex, though, and the complex odd-order harmonic distortions are much more audible, even in miniscule amounts.
