Kunezizathu eziningi zokuthi kungani kungase kudingeke sazi izinga lomsindo elisizungezile. Isibonelo, uma sinomakhelwane othanda ukudlala umculo kakhulu, noma ukuthola izinga lomsindo wemvelo esingawuthwala endaweni yethu yokusebenza. Kuzo zonke lezi zimo, i- izinhlelo zokusebenza zokukala ama-decibel. Kulokhu okuthunyelwe sizohlaziya okunye okuhle kakhulu.
El i-decibel (dB) isilinganiso esisetshenziselwa ukuveza izinga lamandla noma izinga lokuqina lomsindo. Umkhawulo wokuzwa wendlebe yomuntu unikezwe inani elingu-0 dB. Leso sibalo singalingana, kancane noma ngaphansi, nesokuthula okuphelele, nakuba umuntu ngamunye enokuzwela okuhlukile.
Ukuze sibe nombono olinganiselwe wenani lama-decibel, okungukuthi, izinga lomsindo esivezwa kulo ekuphileni kwethu kwansuku zonke, singanikeza izibonelo ezithile: umsindo wezwi lomuntu engxoxweni evamile (ngaphandle kokumemeza) icishe ibe ngu-40 dB, leyo yesicoci se-vacuum esebenza ngesikhathi sokuhlanza indlu ingu-70 dB kanye ne-drill kagesi engu-90 dB.
I-World Health Organization (WHO) isungula i- umkhawulo wama-55 dB njengomkhawulo ongabekezeleleka ukuze kube nendawo yokuhlala eyanele. E-Spain, yimikhandlu yedolobha enquma amazinga omsindo avunyelwe ezindaweni zokuhlala, ngaphakathi kwemingcele ebekwe yi- Umthetho Womsindo. Ngokuvamile, izilinganiso ezilandelayo ziyasebenza:
- Emini (kusukela ngo-8 ekuseni ukuya ku-22 p.m.) awukwazi ukweqa u-35 dB.
- Ebusuku (kusuka ngo-22:8 kuye ku-30am) lo mkhawulo wehliswa ube ngu-XNUMX dB.
Lawa mahora namazinga angase ahluke ngamaholide nangezimpelasonto, nakuba kulula ukuzazi futhi uzihloniphe ukuze ugweme unswinyo lwezomnotho zokuphatha. Kulapho amamitha e-decibel eqala khona ukusebenza, noma okungcono kakhulu, izinhlelo zokusebenza zokukala ama-decibel: ukwazi ukuthi singaphakathi kwemikhawulo esemthethweni.
Imitha yomsindo (SPL)
Ngaphandle kwamamitha ezinga lomsindo wekhwalithi yobuchwepheshe, uhlelo lokusebenza Imitha yomsindo (SPL) Ingelinye lamathuluzi angcono kakhulu esingawasebenzisela ukukala imisindo nomsindo wendawo. Igama elithi SPL limele Izinga lokucindezela komsindo, okuyilokho ngempela lolu hlelo lokusebenza olukalayo ngezinga eliphezulu lokushuna kahle.
I-plus eyengeziwe isixhumi esibonakalayo sayo esihle, isici sayo esibonakalayo esingasenza ngokwezifiso ngokuhlukile imiklamo ephefumulelwe amageji esitayela sakudala noma se-vintage. Isixazululo esihle kakhulu, futhi esisebenzayo.
I-Decibel X
Imitha yomsindo enhle kakhulu, inembe kakhulu futhi inokwethenjelwa. I-Decibel X Inikeza izilinganiso ezilinganiselwe ngaphambili ezingahlanganiswa nezinye izinhlelo zokusebenza futhi futhi isivumela ukuthi sakhe umlando futhi sabelane ngemiphumela yezilinganiso zethu ngezinkundla zokuxhumana.
Ngebanga elijwayelekile lokulinganisa ukusuka ku-30 dB ukuya ku-130 dB, imiphumela iboniswa kusetshenziswa izithombe ezisebenzayo ngesikhathi sangempela. Iphinde ibe ne- "Gcina idivayisi ivukile". ukwenza ukurekhoda kwesikhathi eside, isibonelo, ukwazi izinga lomsindo wehhovisi phakathi nosuku lonke lokusebenza. Isebenza kakhulu.
Isihlaziyi Somsindo
Imitha yomsindo ephrofeshinali esinika ulwazi oluningiliziwe noluthembekile ngamaleveli omsindo we-ambient. Isihlaziyi Somsindo Iyakwazi ukwenza ukuhlaziya okuvumelanayo kwamashaneli ahlukahlukene futhi isinikeze ukumelwa okuyingcaca kwazo.
Akuyona imitha yomsindo elula ukuyisebenzisa, kodwa a ithuluzi eliyinkimbinkimbi okudinga ulwazi oluncane lwama-acoustic ohlangothini lomsebenzisi. Imiphumela yakhona inikezela ngemininingwane yobuchwepheshe okungenzeka ingadingeki kubantu abaningi, kodwa ukusetshenziswa kochwepheshe kungase kuthakazelise kakhulu. Kunoma ikuphi, singancoma kuphela lolu hlelo lokusebenza kochwepheshe.
I-Sound Meter Pro
Ukuvala uhlu, enye yezinhlelo zokusebenza ezinhle zokukala ama-decibel esinawo. I-Sound Meter Pro iyisicelo samahhala kodwa esikwazi ukunikeza izilinganiso zomsindo ezisezingeni eliphezulu. Lokhu kungenxa yokuthi ilinganiselwe kusetshenziswa i-Nor140, imitha yezinga lomsindo enembayo ephezulu.
Ngaphezu kokulinganisa amazinga omsindo wendawo, uhlelo lokusebenza lisivumela ukuthi silondoloze izilinganiso zethu ngezindawo ezihambisanayo. Ine-interface elula nenhle. Ukugqamisa neyakhe i-vibrometer ehlanganisiwe esebenzisa inzwa yokusheshisa ukukala ukudlidliza okuqinile. Noma ngisho nokuzamazama komhlaba.
Ngendlela yokuphetha, kubalulekile ukwazi ukuthi izinhlelo zokusebenza ziwusizo kangakanani ukukala ama-decibel kusetshenziswa omakhalekhukhwini bethu. Njengoba sesibonile, kunjalo amathuluzi awusizo kakhulu futhi alula ukusebenzisa ukuthi bangasinika ukufundwa okuthembekile mayelana namazinga we-acoustic wekhaya noma indawo yokusebenza. Kodwa-ke, imiphumela yayo ayivumelekile ngaphakathi kohlelo Lokulondoloza Ukuzwa komsebenzi ngaphandle kwalapho izilinganiso zenziwe kusetshenziswa umbhobho wohlobo 2 kanye nokulinganiswa kwedivayisi okugunyaziwe ngaphambi nangemuva kwesilinganiso ngasinye.
