harmonics
The science of musical sounds
plural form of harmonic
{i} study or theory of musical sounds; healing method of chanting that was developed and practiced by Tibetan monks
A sinusoidal quantity having a frequency that is an integral multiple (X2, X3 etc ) of a fundamental (X 1) frequency
An overtone whose frequency is a whole-number multiple of the intitial or base frequency The whole number multiples of a frequency that determines the timbre recognition of an instrument's sound
Integral multiples of a puretone The tone itself is the 1st harmonic, or fundamental frequency; twice the frequency of the tone is the 2nd harmonic; three times the frequency of the tone is the 3rd harmonic; etc
Sound & vibration due to engine vibration at high speeds Spec Sheet (Specification Sheet) issued by GSARA & calls out minimum measurement requirements for each racing aircraft
Harmonics are sinusoidal voltages or currents having frequencies that are integer multiples of the frequency at which the supply system is designed to operate Harmonic distortion originates is the nonlinear characteristics of device and loads on the power system The levels are described by the complete harmonic spectrum with magnitudes and phase angles of each individual harmonic component The IEEE Standard 519-1992 provides guidelines for harmonic current and voltage distortion levels on transmission and distribution circuits
Harmonics or overtones provide the characteristic timbre of instruments and voices and occur above and below the so-called fundamental or base note The popular soft plastic pipe can be used to explore harmonics -- as you swirl it around faster and faster, you "climb up" from one harmonic to the next You can also over-blow a glass bottle with higher and higher air velocity for the same experiment The first harmonic is one octave higher than the fundamental The second harmonic an octave + a fifth The third harmonic is two octaves higher than the fundamental The forth adds another third Odd-order harmonics are more pleasing to the human ear because they act as octave-doublers Most tube amps have high odd-order distortion, which causes a euphonic coloration Even-order distortion introduces fifth, thirds and diminished thirds and isn’t harmonically benign THD specs report on the Total Harmonic Distortion behavior of amplifiers
(h): Integer multiples of the fundamental frequency e g
sounds that are multiples of the fundamental frequency
Also called overtones, these are vibrations at frequencies that are multiples of the fundamental Harmonics extend without limit beyond the audible range They are characterized as even-order and odd-order harmonics A second-order harmonic is two times the frequency of the fundamental; a third order is three times the fundamental; a fourth order is four times the fundamental; and so forth Each even-order harmonic: second, fourth, sixth, etc -is one octave or multiples of one octave higher than the fundamental; these even-order overtones are therefore musically related to the fundamental Odd-order harmonics, on the other hand: third, fifth, seventh, and up-create a series of notes that are not related to any octave overtones and therefore may have an unpleasant sound Audio systems that emphasize odd-order harmonics tend to have a harsh, hard quality
The higher multiples of the fundamental frequency superimposed on an ac wave form Harmonics can create power line disturbances that damage sensitive electronic equipment such as computers They also add current to the system neutral conductor
The fundamental and the tones whose frequencies are whole number multiples of the fundamental
Secondary and less distinct tones which accompany any principal, and apparently simple, tone, as the octave, the twelfth, the fifteenth, and the seventeenth
A series of partials with frequencies that are pie multiples of a fundamental frequency (In a harmonic series, the first harmonic would be the fundamental, second harmonic the first overtone )
The name is also applied to the artificial tones produced by a string or column of air, when the impulse given to it suffices only to make a part of the string or column vibrate; overtones
the vibration of an air column or string is divided into fractions (for example, two halves, three thirds, etc) which sound simultaneously to produce sound
plural of harmonic
The harmonic tones produced by a vibration that go to make up the aural spectrum of any particular note, or grouping of notes
