The effects of harmonic distortion on equipments
IEE Colloquium on Sources and Effects of Harmonic Distortion in Power Systems, 1997All transformers are affected by harmonics given that any power system is contaminated to some degree by them. What is of interest and concern are the extremes, albeit known and in most cases predictable extremes. Some loads are known as classical harmonic generators so far as transformers are concerned. Any transformer connected to a converter load or

Harmonic distortion in electret microphones
Applied Acoustics, 1991Abstract Using the harmonic-balance method, an approximate solution for the differential equation describing the relationship between the output voltage of the electret microphone and its air-gap thickness is obtained. Closed form expressions are derived for the amplitudes and phases of the fundamental, second- and third-harmonic components of the ...

Harmonic Distortion Perception Threshold
2007One of the quality factors of almost every professional audio instrument is the total harmonic distortion (THD) factor. In view of attempts to reduce it to the smallest possible values, a question comes up: what is the real human threshold of perceiving harmonic distortion?

Second Harmonic Distortion in Horns
1994Figure 44 presents solutions to the following equation: $$ \% 2ndharmonic = 1.76 \sqrt {{{I_T}}} (f/{f_c}) \times {10^{{ - 2}}} $$ (44.1) where IT is the acoustic intensity at the horn throat in watts per square meter, fc is the nominal cutoff frequency of the horn, and f is the driving frequency.
