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…

THD stands for Total Harmonic Distortion and can be used to estimate the degree to which a system is nonlinear. A THD measurement can be made by applying a sine wave as an input to a system, and measuring the total energy which appears at the output of the system at harmonics of the input frequency.

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 is the addition of new tones to the audio signal. These distortion products occur at integer multiples of the original signal’s frequency and are harmonically related to the original tone. When the signal is a single sine wave (tone) of frequency f1, harmonic tones are f2, f3, etc., at integral multiples of the original tone.

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.

A common type of amplifier distortion is called harmonic distortion. It can arise if any component in the amplifer clips the peaks of the waveform. A common specification for high fidelity amplifiers is the total harmonic distortion. This distortion may be less than 1%, or even less than 0.5% from 20-20,000 Hz for high quality amplifiers.

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.
