Nansi imfihlo yokuphinda kabili izinga lokucindezela komsindo!

Emhlabeni womsindo womsebenzi, ukufuna ikhwalithi yomsindo ephezulu kanye nokufakwa akupheli. Enye yentuthuko ebaluleke kakhulu kubuchwepheshe bokuqinisa umsindo kube ukuthuthukiswa kwezinhlelo zemigqa yomugqa. Lezi zinhlelo seziphenduke inketho yokukhethwa kukho kochwepheshe kusukela kumakhonsathi kuya emicimbini yezinkampani, futhi ngesizathu esihle. Kulesi sihloko, sizohlola ukuthi yini eyenza amasistimu omsindo womugqa adume kangaka ezindaweni zomsindo okhokhelwayo futhi sembule izimfihlo zekhono lawo lokuphinda kabili izinga lokucindezela komsindo.

Ukuqonda Line Array Technology

Ingqikithi yomugqa womugqa uchungechunge lwezipikha ezihlelwe ziqonde phezulu. Lokhu kulungiselelwa kuvumela ukusakazeka komsindo okulawulwa kakhulu kunokulungiselelwa kwesipikha esivamile. Idizayini ye-array yomugqa iyenza ikwazi ukukhiqiza umsindo ebangeni elide kuyilapho igcina ukucaca nokuvumelana. Lokhu kubaluleke kakhulu ezindaweni ezinkulu, njengoba zidinga umsindo ukuze ufinyelele kuwo wonke amakhona ngaphandle kokulahlekelwa ikhwalithi yomsindo.

Isihluthulelo ekusebenzeni kahle kwezipikha zomugqa yikhono lazo lokusebenzisa isimiso sokuphazanyiswa kwamagagasi. Uma izipikha eziningi zihlelwa ziqonde phezulu, zisebenza ndawonye ukuze zakhe i-wavefront ehambisanayo. Lokhu kusho ukuthi amaza omsindo esipikha ngasinye ayanezelana, okuholela emazingeni aphezulu okucindezela komsindo (SPL) kude. Lesi simo sivame ukubizwa ngokuthi "ukuhlanganisa", futhi yilokhu kuhlanganisa okuvumela amalungu afanayo emigqa ukuthi anikeze umsindo onamandla ngaphandle kokukhulisa kakhulu.

Izinzuzo ze-Line Array Systems

1. Ukufakwa okunwetshiwe: Esinye sezizathu eziyinhloko zokusebenzisa amasistimu we-line array ekusebenzeni okuphrofeshinali yikhono lawo lokuhlinzeka ngisho nokuzwakala komsindo endaweni enkulu. Ukusethwa kwesipikha somdabu kuvame ukuphumela ekusabalaliseni komsindo okungalingani, okuholela ezwini elikhulu kakhulu kwezinye izindawo kanye nevolumu enganele kwezinye izindawo. Amalungu afanayo emigqa angenziwa ngendlela oyifisayo kuma-acoustics athile wendawo, ukuqinisekisa ukuthi wonke amalungu ezithameli athola umuzwa wokulalela ongaguquki.

2. Nciphisa impendulo: Impendulo iyinkinga evamile ekuqiniseni umsindo obukhoma, ikakhulukazi uma usebenzisa imibhobho. Amalungu afanayo emigqa angamiswa ngendlela enciphisa amathuba empendulo. Ngokuqondisa umsindo kude kumakrofoni nezinye izisetshenziswa ezizwelayo, onjiniyela bomsindo bangazuza inzuzo ephezulu ngaphambi kwempendulo, okuholela ekusebenzeni okunamandla kakhudlwana.

3. Ukukaleka: Amasistimu we-array ye-line scalable kakhulu futhi afanele izimo ezihlukahlukene zohlelo lokusebenza. Kungakhathaliseki ukuthi iklabhu encane noma inkundla yezemidlalo enkulu, uhlu lomugqa lungalungiselelwa ukuhlangabezana nezidingo ezithile zomcimbi. Kubasebenzi abahlakaniphile abavame ukusebenza ezindaweni ezahlukene, lokhu kuvumelana nezimo kuyinzuzo enkulu.

I-4.Aesthetics: Ngaphezu kwezinzuzo zayo zobuchwepheshe, imigqa yemigqa ibuye ibe nokubukeka okucacile, kwesimanje. Lokhu kubaluleke kakhulu ezenzakalweni eziphezulu, lapho ukwethulwa okubukwayo kubaluleke kakhulu njengekhwalithi yomsindo. Idizayini ehlangene yamalungu afanayo emigqa iwavumela ukuthi ahlangane ngaphandle komthungo nesethingi yesiteji, iqinisekise ukuthi ukunaka kwezithameli kuhlala kugxile ekusebenzeni.

Phinda kabili izinga lokucindezela komsindo

Manje, ake singene ezimfihlakalweni zokuthi umugqa uhlanganisa kanjani kabili izinga lokucindezela komsindo. Umqondo wezinga lokucindezela komsindo ubalulekile ekuqondeni ukuphakama okuzwakalayo komsindo. Ikalwa ngama-decibel (dB), futhi ukuguqulwa okungu-10 dB kumele ukukhuphuka okuphindwe ka-10 kokuqina komsindo. Ngakho-ke, ukuphinda kabili umsindo ozwakalayo, ukukhuphuka okucishe kube ngu-10 dB kuyadingeka.

Amalungu afanayo emigqa afinyelela lesi senzo esimangalisayo ngomklamo wawo oyingqayizivele nokumisa. Lapho izikhulisa-zwi zipakishwe zibheke phezulu, zakhe igagasi elihambisanayo elivumela umsindo ukuba uye kude futhi ngamandla amakhulu. Lokhu kusebenza ikakhulukazi ezindaweni ezinkulu lapho kudingeka khona ukusabalalisa amabanga amade. Ngokusebenzisa izikhulisazwi eziningi ohlwini lomugqa, onjiniyela bomsindo bangakhuphula ngempumelelo ileveli yokucindezela komsindo (SPL) ngaphandle kwesidingo samandla engeziwe.

Ukwengeza, ikhono lokulawula ukusakazeka okuqondile komsindo linika amandla ukuma okunembe kwezethameli. Lokhu kusho ukuthi umsindo ungafinyelela izethameli ngokuqondile kuyilapho unciphisa ukubonakaliswa okuvela ezindongeni nophahla olungangcolisa umsindo. Umphumela uba umsindo ocacile, onamandla ogcwalisa indawo ngaphandle kokukhungatheka.

Kafushane
Sekukonke, amasistimu omsindo womugqa aguqule indlela okwenziwa ngayo okuphrofeshinali okwethulwa ngayo. Ikhono labo lokuhlinzeka ngekhava elilinganayo, ukunciphisa impendulo, nokuzivumelanisa nosayizi abahlukahlukene bendawo kubenza babe ithuluzi elibaluleke kakhulu konjiniyela bomsindo. Imfihlo yempumelelo yabo ilele ekwakhiweni kwabo okuyingqayizivele, okuphinda kabili izinga lokucindezela komsindo ngokuphazanyiswa kwegagasi nokuqagela komsindo okuhambisanayo.

Njengoba ubuchwepheshe buqhubeka nokuvela, imigqa efanayo ngokungangabazeki izoqhubeka nokuhola phambili ezisombululo zomsindo ezichwepheshile. Kunoma ubani obambe iqhaza ekudlalweni okubukhoma, ukuqonda izinzuzo nezimiso zokusebenza zamasistimu omugqa ofanayo kubalulekile ekudaleni umuzwa omuhle kakhulu womsindo. Noma ngabe ungunjiniyela womsindo, umenzi noma umhleli womcimbi, usebenzisa ubuchwepheshe be-line array kungathatha ukusebenza kwakho kufinyelele phezulu, kuqinisekiswe ukuthi yonke inothi izwakala kahle futhi wonke umzuzu omangalisayo ungazwakala.
