I-Harmonics ikunceda ukuhlukanisa izixhobo zomculo ezahlukeneyo
Ukuba ufunde naluphi na uqeqesho lwe- acoustics , iteknoloji yesalathisi ye-radios, okanye ubunjineli bombaneli, unokukhumbula ukhupha isihloko sobunzima be-harmonic. Ingxenye ebalulekileyo yendlela umculo uvezwe ngayo kwaye uqondwe. I-fremonic frequency yinkalo enye esinceda ngokuchanekileyo imilinganiselo ekhethekileyo yomsindo owenziwe ngezixhobo ezahlukeneyo, nangona badlala inqaku elifanayo.
Inkcazo yeHarmonic Frequency
I-fremonic frequency yinto ephindaphindiweyo iphinda iphinda iphinda iphindwe ngokuphindaphindiweyo, eyaziwa njengexesha eliqhelekileyo. Ukuba isangqa esisiseko sisetyenziswe kwi- hertz ye- 500, ibona i-frequency ye-harmonic yokuqala kwi-1000 hertz, okanye iphindwe kabini. Inqanaba lesibini le-harmonic lwenzeka kwi-1500 hertz, eliphindwe kathathu kwixesha eliqhelekileyo, kwaye inqanaba lesithathu le-harmonic li-2000 hertz, eliyi-quadruple ye-frequency frequency, njalo njalo.
Ngomnye umzekelo, i-harmonic yokuqala ye-frequency ye-750 hertz yi-1500 hertz, kwaye i-harmoniki yesibili ye-750 hertz ngu-2250 hertz. Zonke ii-harmonics zihamba ngexesha eliqhelekileyo kwaye zinokuphulwa phantsi kwinqanaba leenombolo kunye ne-antinodes.
Iimiphumo zeHarmonic Frequency
Phantse zonke izixhobo zomculo zivelisa uhlobo olumile olumatshini olumile oluqulethe iimbalo eziphambili kunye nezihambelanayo. Ukubunjwa ngokuchanekileyo kwezi zihlandlo kuvumela indlebe yomntu ukuba iqonde ukungafani phakathi kwamagama amanqaku amabili okuculayo ngokubambisana kwinqanaba elifanayo (ubukhulu) kunye nomgangatho (amplitude). Nantsi indlela esiyazi ngayo ukuba igitala izandile njengegitala kwaye ayikho i-oboe okanye ixilongo okanye ipayili okanye idrama. Ngaphandle koko, wonke umntu kunye nayo yonke into iyavakala enye. Iimvumi ezinobuchule ziyakwazi ukuhlalutya izixhobo ngokuphulaphula nokuthelekisa ii-harmonic ezikhoyo phakathi kohlengahlengiso.
Harmonics Versus Overtones
Ixesha elithi "overtones" lisetyenziswe rhoqo kwiingxoxo ezinxulumene neefowuni ze-harmonic. Nangona i-harmonic efanayo yesibini i-harmonic yokuqala, i-harmoniki yesithathu yinto yesibini yesibini, kwaye njalo-le mibini ibini ihlukileyo kwaye iyingqayizivele. I-Overtones ifake kwizinga elipheleleyo okanye isiqalo sesandi sokudlala.
Ukuphazamiseka kwesiHarmonic Frequency kwi-Speakers
Abathengi banomsebenzi wokunikezela ukubonakaliswa ngokuchanekileyo kwama-harmonic kwezixhobo abazenzayo. Ukulinganisa umahluko phakathi kwezandi ezingenayo kunye nemveliso yezithethi, i- Specification yeHarmonic Distortion (THD) eyabelwe kwisithethi ngasinye-esezantsi kumanqaku, ngcono ukuhanjiswa kwesithethi. Umzekelo, i-THD ye-0.05 ithetha ukuba iipesenti ezingama-0.05 zesandi esivela kwisithethi sichasene okanye siphathwe kakubi.
Izinto ze-THD kubathengi basekhaya kuba banako ukusebenzisa amanqaku e-THD adweliswe kwisithethi ukuvavanya umgangatho ophezulu abanokulindela ukuwufumana kwisithethi. Ngokwenene, ukungafani kwezixhobo ze-harmonics zincinci, kwaye abaninzi abantu abayi kubona isahlulo sepesenti kwi-THD kwisithethi esinye ukuya kwesinye.
Nangona kunjalo, xa i-fremonic frequency iphikisiwe ngamaphesenti a-1, izixhobo zokurekhoda izandi ezingekho ngokwemvelo, ngoko kuqikelele ukuhlala kude nezithethi ekupheleni kwe-THD.
