THD to dB - convert percent % to decibels dB percentage ...
http://www.sengpielaudio.com/calculator-thd.htm
Nonlinear distortions are given as distortion attenuation a k in dB or as damping factor k (THD) in percent. Total harmonic distortion (THD) is defined as the ratio of the rms voltage of the harmonics to that of the fundamental component. This is accomplished by using a spectrum analyzer to obtain the level of each harmonic and performing an rms summation.

Total Harmonic Distortion - Universal Audio
https://www.uaudio.com/blog/total-harmonic-distortion/
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. A sinusoidal input is used because sinusoids ...
Sennheiser HD800S Unveiled! | Page 341 - Head-Fi
https://www.head-fi.org/threads/sennheiser-hd800s-unveiled.785577/page-341
Interesting site. Thanks. Just looking at the measurements on Innerfidelity, the HD800S has about 4-5% more distortion at 20Hz and 100dB (SPL...not distortion)than the HD800. What's funny to me is that many folks on Head-Fi talk about 'fidelity' and being as 'true to the source' (i.e. lowest distortion) as possible but then ignore these things when it doesn't support …
Inaccurate THD measurement - Pico Technology
https://www.picotech.com/support/viewtopic.php?t=13823
Another weird aspect is the measurement of THD + N (dBc). In a first test, when the spectrum analyzer was set to 1 MHz, at maximum power amplifier was obtained THD+N = 48.68dBc and THD = 0.368%. Then, I reduced the bandwidth of at spectrum analyzer, in this case 6kHz, and THD+N reached ~45dBc and THD=~1%.
Convert THD+N percentage ratio in dB? : audiophile
https://www.reddit.com/r/audiophile/comments/b5mszm/convert_thdn_percentage_ratio_in_db/
There are a few rules of thumb, e.g. a shift of the decimal point is equal to 20 dB. e.g. if you have a THD of 10 %, then the SPL of the harmonics will be 20 dB lower than the SPL of the fundamental. if you have a THD of 1 %, it‘s 40 dB lower. 0.1 % = 60 …
