Iinkqubo zesandi ziyinxalenye ebalulekileyo yobomi bethu, zidlala indima ebalulekileyo kwezolonwabo lwasekhaya kunye nokuveliswa komculo ochwephesha. Nangona kunjalo, kubantu abaninzi, ukukhetha izixhobo zesandi ezifanelekileyo kunokuba yinto edidayo. Kule tweet, siza kuhlola ezinye izalathisi eziphambili ezijikeleze isandi ukukunceda uqonde ngcono indlela yokukhetha izixhobo zesandi ezifanela iimfuno zakho.

1. Impendulo rhoqo

Impendulo yemvamisa ibhekisa kwisiphumo somthamo wezixhobo zesandi kwiimvamisa ezahlukeneyo, ezihlala zilinganiswa ngeHertz (Hz). Kwizixhobo zesandi ezisemgangathweni ophezulu, kufuneka zikwazi ukugubungela uluhlu olubanzi lweemvamisa kwaye ziboniswe ngokucacileyo ukusuka kwiithoni eziphantsi ukuya kweziphezulu. Ke ngoko, xa ukhetha izixhobo zesandi, qwalasela uluhlu lwazo lwempendulo yemvamisa ukuqinisekisa ukuba ungonwabela amava esandi apheleleyo.

2. Inqanaba loxinzelelo lwesandi

Inqanaba loxinzelelo lwesandi luphawu olulinganisa umthamo wokuphuma kwezixhobo zesandi, ezihlala zilinganiswa ngee-decibels (dB). Inqanaba loxinzelelo lwesandi eliphezulu lithetha ukuba izixhobo zesandi zinokubonelela ngokukhupha isandi okunamandla, okufanelekileyo kwiziganeko ezinkulu okanye kwiindawo ezifuna ukuzalisa igumbi lonke. Nangona kunjalo, kubalulekile ukuba ungalandeli ngokungaboniyo amanqanaba oxinzelelo lwesandi, njengoko ivolumu ephezulu inokubangela umonakalo kwiindlebe. Ke ngoko, xa ukhetha izixhobo zesandi, kubalulekile ukuqwalasela imeko oyisebenzisayo kwaye kufuneka ulinganise ivolumu kunye nomgangatho wesandi.

3. Ukuguqulwa kweHarmonic

Ukuphazamiseka kweHarmonic kubhekisa kukuphazamiseka kwesandi okongezelelweyo okuveliswa zizixhobo zesandi xa kwandiswa isandi, okuhlala kubonakaliswa njengepesenti. Ukuphazamiseka kweHarmonic okuphantsi kuthetha ukuba izixhobo zesandi zinokuphinda zivelise isignali yesandi yokuqala ngokuchanekileyo, zibonelele ngomgangatho wesandi ocacileyo nowenene. Ke ngoko, xa ukhetha izixhobo zesandi, kubalulekile ukuba unikele ingqalelo kwinqanaba lokuphazamiseka kweHarmonic ukuqinisekisa ukuba unako ukonwabela amava esandi asemgangathweni ophezulu.

4. Umlinganiselo wesignali kwingxolo

Umlinganiselo wesignali kwingxolo sisalathisi esilinganisa umlinganiselo phakathi kwesignali yesandi ephumayo yesixhobo sesandi kunye nengxolo yangasemva, edla ngokulinganiswa ngee-decibels (dB). Umlinganiselo ophezulu wesignali kwingxolo uthetha ukuba izixhobo zesandi zinokubonelela ngemiqondiso yesandi ecacileyo necocekileyo, nto leyo enciphisa impembelelo yengxolo yangasemva kumgangatho wesandi. Ke ngoko, xa ukhetha izixhobo zesandi, kubalulekile ukukhangela iimveliso ezinemilinganiselo ephezulu yesignali kwingxolo ukuqinisekisa ukuba unamava angcono esandi.

5. Iyunithi yomqhubi

Iyunithi yomqhubi wezixhobo zesandi ibandakanya izinto ezifana nezithethi kunye nee-subwoofers, ezichaphazela ngokuthe ngqo umgangatho wesandi kunye nokusebenza kwezixhobo zesandi. Iindidi ezahlukeneyo zeeyunithi zesandi zifanelekile kwiindidi ezahlukeneyo zezandi kunye nokusebenza kwesandi, njengeeyunithi ze-dynamic coil drive, iiyunithi ze-capacitive drive, njl. Ke ngoko, xa ukhetha izixhobo zesandi, qaphela uhlobo kunye neenkcukacha zeyunithi yaso yomqhubi ukuqinisekisa ukuba inokuhlangabezana neemfuno zakho zesandi.

6. Impendulo yesigaba

Impendulo yesigaba kukukwazi kwezixhobo zesandi ukuphendula kutshintsho lwesigaba kwimiqondiso yokufaka, nto leyo echaphazela ngokuthe ngqo iimpawu zexesha-indawo yemiqondiso yesandi. Kwizixhobo zesandi ezikumgangatho ophezulu, impendulo yesigaba kufuneka ibe yethe ngqo, igcine ubudlelwane bexesha lesignali yesandi ingatshintshanga. Ke ngoko, xa kukhethwa izixhobo zesandi, kufuneka kunikwe ingqalelo kwiimpawu zazo zempendulo yesigaba ukuqinisekisa ukuchaneka nokucaca kwesignali yesandi.

7. Isisombululo sefrikhwensi

Isisombululo sefrikhwensi sibhekisa kubuchule bezixhobo zesandi ukwahlula imiqondiso yefrikhwensi ezahlukeneyo, ezidla ngokulinganiswa ngeHertz (Hz). Isisombululo sefrikhwensi ephezulu sithetha ukuba izixhobo zesandi zinokwahlula ngokuchanekileyo imiqondiso yesandi yefrikhwensi ezahlukeneyo, zibonelela ngomgangatho wesandi ocolekileyo nochanekileyo. Ke ngoko, xa ukhetha izixhobo zesandi, kubalulekile ukuqaphela inqanaba lazo lesisombululo sefrikhwensi ukuqinisekisa ukuba unokufikelela kumava esandi akumgangatho ophezulu.

8. Uluhlu olutshintshayo

Uluhlu olutshintshayo lubhekisa kuluhlu lomahluko phakathi kwemiqondiso ephezulu neyona incinci enokusetyenzwa zizixhobo zesandi, ngokuqhelekileyo ilinganiswa ngee-decibels (dB). Uluhlu olukhulu olutshintshayo luthetha ukuba izixhobo zesandi zinokucwangcisa uluhlu olubanzi lwemiqondiso yesandi, zibonelela ngoluhlu olukhulu lotshintsho lwevolumu kunye neenkcukacha ezityebileyo zesandi. Ke ngoko, xa ukhetha izixhobo zesandi, qaphela iimpawu zazo zoluhlu olutshintshayo ukuqinisekisa ukuba unokonwabela iziphumo zesandi ezingcono.

9. Ukuvumelana kwesigaba

Ukuhambelana kwesigaba kubhekisa kwinqanaba lokuvumelana phakathi kwezigaba zezixhobo ezininzi zesandi xa kukhutshwa imiqondiso yesandi, nto leyo edla ngokuba yinto ebaluleke kakhulu kwiinkqubo zeziteshi ezininzi. Ukuhambelana kwesigaba okuhle kuthetha ukuba imiqondiso yesandi evela kwiitshaneli ezahlukeneyo inokuhlala ihambelana, inika amava esandi anomlinganiselo wesithathu kwaye ayinyani. Ke ngoko, xa ukhetha inkqubo yesandi eneziteshi ezininzi, kubalulekile ukuba unikele ingqalelo kwiimpawu zayo zokuhambelana kwesigaba ukuqinisekisa ukuba unokufezekisa iziphumo zesandi ezinzulu ngakumbi.
