Harmonics Ib qho kev sib haum xeeb yog ib qho ntawm ib qho kev nce qib ntawm cov khoom siv sonic uas suab nrov tshaj qhov nrov zaus. Qhov ntau zaus harmonics uas suab saum lub hauv paus tsim lub harmonic spectrum harmonic spectrum A harmonic spectrum yog ib spectrum uas muaj cov zaus Cheebtsam uas nws frequencies yog tag nrho cov zauv ntau ntau ntawm cov zaus zaus; cov zaus no hu ua harmonics. "Cov ib feem ntawm tus kheej tsis hnov txog tab sis tau muab sib xyaw ua ke los ntawm pob ntseg rau hauv ib lub suab." https://en.wikipedia.org › wiki › Harmonic_spectrum

ntawm lub suab. … Harmonics muaj qhov amplitude qis dua qhov zaus.
Puas yog qhov tseem ceeb tshaj plaws?
Vim qhov tseem ceeb yog qhov qis tshaj plawsthiab tseem pom tau tias yog qhov nrov tshaj plaws, pob ntseg qhia tias nws yog lub suab tshwj xeeb ntawm suab paj nruag [harmonic spectrum]…. Cov neeg ib feem tsis tau hnov dab tsi tab sis raug muab sib xyaw los ntawm pob ntseg rau hauv ib lub suab.
Dab tsi yog tag nrho cov resonant frequencies siab dua qhov tseem ceeb zaus?
Qhov qis tshaj resonant zaus hu ua qhov tseem ceeb, thaum tag nrho cov resonant ntau zaus hu ua overtones. Tag nrho cov resonant zaus yog ib qho sib npaug ntawm qhov tseem ceeb, thiab lawv raug hu ua harmonics.
Puas yog cov zaus zaus yog qhov qis tshaj plaws?
Qhov qis tshaj plaws uas tsim los ntawm ib qho cuab yeej tshwj xeeb yog hu ua qhov zaus zaus. Lub hauv paus zaus tseem hu ua thawj harmonic ntawm ntsuas.
Qhov zaus ntawm qhov zaus yog dab tsi?
The fundamental zaus (n=1) is ν=v/2l. Cov zaus ntau dua, hu ua harmonics lossis overtones, yog ntau qhov tseem ceeb. Nws yog kev cai xa mus rau lub hauv paus raws li thawj harmonic; n=2 muab qhov thib ob harmonic lossis thawj overtone, thiab lwm yam.
