Ukuthi umsindo uthathwa njenge sina nomaokubukhali kuya ngenani lokudlidliza elenza ngeyunithi ngayinye yesikhathi. Lapho kunyakaza kaningi (imvamisa ephezulu), umsindo uyanda. Uma ukudlidliza kungavamile (imvamisa ephansi) umsindo uzoba mkhulu kakhulu.
Umsindo uphansi noma uphezulu kuye ngokuthi uvama kangakanani. Imvamisa yemisindo ilinganiswa kuHertz (Hz) okuyinombolo yokudlidliza kwamaza ngomzuzwana.
Imisindo engabonakala endlebeni yomuntu iphakathi kwama-Hz angama-20 kuye kwangama-20 000. Le amplitude ibizwa ngokuthi “i-spectrum ezwakalayo”.
Kodwa-ke, ngezindlela zobuchwepheshe, imisindo itholakele engazwakali kubantu kepha izilwane ezahlukahlukene ziyabona noma zikhiphe njengendlela yokuxhumana. Isibonelo, izinhlobo ezahlukahlukene zemikhomo ziyakhipha futhi zibone ziphansi kakhulu (ngemvamisa ye-10 Hz) futhi iphakeme kakhulu (enezikhathi ezingama-325 kHz noma ama-325,000 Hz) imisindo. Lokhu kusho ukuthi ezinye izinhlobo zemikhomo zixhumana nemisindo engaphansi kobubanzi obuzwakalayo kubantu, kuyilapho ezinye zikhuluma ngemisindo engaphezulu kakhulu kwalokho esingakuzwa.
- Iyahamba. Imisindo ephezulu kakhulu ibhekwa njengaleyo edlula u-5 kHz, olingana no-5,000 Hz.
- Amathuna. Imisindo yeBass ivame ukubhekwa njengaleyo engaphansi kwama-250 Hz.
- Lesisemkhatsini.Ububanzi obuphakathi kuka-250 Hz no-5,000 Hz buhambisana nemisindo ephakathi.
Ukuvama komsindo akufanele kudidaniswe nevolumu. Umsindo ophezulu ungaba namandla amakhulu (ivolumu ephezulu) noma amandla aphansi (ivolumu ephansi) ngaphandle kokuthinta imvamisa yegagasi.
IVolumu ichazwa njengenani lamandla adlula ebusweni ngomzuzwana.
Umculo waseNtshonalanga usebenzisa amanothi aqoqelwe "octave" ngokuya ngemvamisa yawo yamagagasi. Ukusuka kokuphansi kuye phezulu, amanothi we-octave ngayinye ahlelwe kanjena: Do, re, mi, fa, sol, la, si.
Bhekafuthi:
- Imisindo enamandla namandla
- Imisindo yemvelo neyokufakelwa
Izibonelo zemisindo ye-bass
- Ukuduma. I-Thunder ikhipha imisindo ephansi kakhulu kangangokuba eminye ayikwazi ukubonwa yindlebe yomuntu (ngaphansi kwama-20 Hz).
- Izwi lowesilisa omdala. Imvamisa, izwi lowesilisa liphakathi kuka-100 no-200 Hz.
- Izwi le-bass. Abaculi besilisa ababizwa nge- "bass" yilabo abakwazi ukuletha amanothi aphakathi kuka-75 no-350 Hz.
- Umsindo webhasi. I-bassoon iyinsimbi ye-woodwind efinyelela imisindo ephansi njengo-62 Hz.
- Umsindo we-trombone. I-trombone iyinsimbi yethusi efinyelela amanothi aphansi njengo-73 Hz.
- C we-octave 0. Ngumsindo ophansi osetshenziswa emculweni waseNtshonalanga. Imvamisa yayo ingu-16,351 Hz.
- Uma kusuka ku-octave 1. Yize icishe ibe ngama-octave amabili ngaphezulu kwe-C ye-octave 0, le B isewumsindo ophansi kakhulu, onamvamisa we-61.73 Hz.Ingaphansi kwamandla omculi we-bass.
Izibonelo zemisindo ephezulu
- Umsindo we-violin. I-violin iyinsimbi enezintambo efinyelela eminye yemisindo enomsindo kakhulu ku-orchestra (ngemuva kwepiyano, enemisindo ehlukahlukene).
- Izwi lezingane. Izingane zivame ukuba namazwi angaphezu kwama-250 noma ama-300 Hz. Yize leli banga lingadluli kuma-Hz angu-5 000 ajwayele ukucatshangelwa imisindo ephezulu, siyawabona lawa mazwi njengezwi eliphakeme uma kuqhathaniswa namazwi abantu abadala.
- Izwi le-soprano. Abaculi besifazane ababizwa ngokuthi "ama-sopranos" bangakhipha amanothi aphakathi kuka-250 Hz no-1,000 Hz.
- Uma owesihlanu wesihlanu. Ngomunye wemisindo emikhulu kunayo yonke i-soprano eqeqeshiwe engayifinyelela, imvamisa ye-987.766 Hz.
- Ingoma yezinyoni. Ubuncane bokukhishwa kwe-birdong yi-1,000 Hz futhi bufinyelela ku-12,585 Hz.Noma amaza aphansi kakhulu aphakathi kwemisindo ephakeme kakhulu uma iqhathaniswa nezwi lomuntu.
- Shaya ikhwela. Imvamisa icishe ibe yi-1,500 Hz.
- Qhubeka nge: Izici Zemisindo eziyi-10
