Ngaphandle kwemisindo, asikwazanga ukukhokhela ukuphakama futhi sithwale ifa lomuntu siliyise lapho esikhona namuhla. Imisindo isenza siphelele, isinika ikhono lokuzwa, ukuzwa nokujabulela yonke into. Kodwa le nto ephelele kakhulu ingaba uhlobo lokwesaba kwangempela uma singakwazi ukuthola umsuka wayo wangempela; ngoba 'ukuba khona okungenamvelaphi' kwenza kube nzima ngempela ukukuchaza, kudala ukwesaba okungaziwa ezingqondweni zethu. Yebo, zikhona, futhi azikachazwa kuze kube namuhla.
1 | I-Taos Hum
Sekuyiminyaka engaphezu kwengu-40, ingxenye encane yabantu (cishe u-2%) emhlabeni wonke bekhononda ngokuzwa umsindo ongaqondakali obizwa kabanzi ngokuthi, “The Hum”. Umthombo walo msindo awaziwa, futhi namanje awuchazwa yisayensi.
2 | UJulia
I-“Julia” iwumsindo ongaqondakali owaqoshwa ngo-March 1, 1999, yi-US National Oceanic and Atmospheric Administration (NOAA). I-NOAA ithe umthombo womsindo cishe bekuyi-Iceberg enkulu eshayeke e-Antarctica. Kodwa-ke, izithombe eziphuma ku-Apollo 33A5 yeNASA zikhombisa isithunzi esikhulu sinyakaza engxenyeni eseNingizimu-ntshonalanga ye-cadre ngesikhathi esifanayo somsindo oqoshiwe. Nakuba zisazohlukaniswa, izithombe ngokusobala zinikeza ulwazi lokuthi lesi sithunzi esingaziwa sikhulu ngo-2x kune-Empire State Building.
3 | IBloop
Eminyakeni engama-70 edlule, izilwandle zomhlaba ziye zavela njengezixhobo zokulalela zomhlaba wonke ezibalulekile, okokuqala ngamanethiwekhi wemakrofoni angaphansi kwamanzi okuskena imikhumbi-ngwenya yezitha ngesikhathi seMpi Yomshoshaphansi, nasemashumini eminyaka amuva nje, ososayensi abacwaninga izilwandle nokwakheka kwangaphakathi Umhlaba.
Omunye wemicimbi edume kakhulu futhi enamandla yamanzi angaphansi kwamanzi, owaziwa ngokuthi yiBloop, waqoshwa yi-US National Oceanic and Atmospheric Administration (NOAA) ngonyaka we-1997. Umcimbi weBloop uthathe cishe umzuzu owodwa futhi wavuka kaningi kusuka ekudumeleni okuphansi. Itholwe ngemibhobho engaphansi kwamanzi ebangeni elingaphezu kwamamayela angu-1 3,000 futhi ibizwakala kakhulu kunemisindo eyenziwe yisiphi isilwane esaziwayo.
Indawo embi yomcimbi owadala iBloop isolwandle eduze ne-Antarctic Circle, kanti uNOAA manje ucabanga ukuthi iBloop ibangelwe umsindo wezinguzunga zeqhwa ezinkulu "ukuzala," noma ukuhlukana, kusukela ekupheleni kwezinguzunga zeqhwa lase-Antarctic nokuwela olwandle .
4 | Umculo Wenyanga
Osomkhathi kusigaba somyalo we-Apollo 10 bezwa "umculo ongajwayelekile" ngenhla ohlangothini olude lwenyanga ngo-1969, ngokusho kwamatheyiphu alalelwayo eNASA avela emishini. Imibhalo yamateyipu yakhishwa yi-NASA ngo-2008, ikhombisa osomkhathi ababekhuluma ngomculo "wasemkhathini" ongazwakala ngaphakathi kumkhumbi-mkhathi. Umsindo uyema ngemuva kwehora, futhi osomkhathi baxoxa ngokuthi kufanele yini batshele abalawuli beNASA ngalokhu.
Ngaleso sikhathi, osomkhathi babengahlangani noMhlaba ngoba umzila womyalo womyalo wawubathwale wawusa ohlangothini olude lwenyanga, olubheke unomphela kude noMhlaba.
NgoFebhuwari 2016, i-NASA yenza ukuqoshwa komphakathi esidlangalaleni kudokhumentari emayelana nomsebenzi we-Apollo 10 - "owomile" wokufika kwenyanga ka-Apollo 11 okwenzeka ngawo lowo nyaka. Ochwepheshe be-NASA no-astronaut we-Apollo 11 uMichael Collins, abezwa umsindo ofanayo ohlangothini lwenyanga, bacabanga ukuthi “umculo” kungenzeka ubangelwe ukuphazanyiswa komsakazo phakathi kwezinsimbi zemodyuli ye-command ne-module yenyanga lapho besondelene .
5 | I-Upsweep
I-Upsweep umsindo ongaziwa okhona okungenani selokhu iPacific Marine Environmental Laboratory iqale ukuqopha i-SOSUS - uhlelo lokuqapha umsindo ngaphansi kwamanzi neziteshi zokulalela emhlabeni wonke - ngo-1991. Umsindo “uqukethe isitimela eside semisindo emincane ye-band-up upsueping yemisindo eminingi isikhathi semizuzwana lilinye, ”kubika i-laboratory.
Indawo okuyimithombo kunzima ukuyikhomba, kepha isePacific, phakathi nendawo maphakathi ne-Australia neNingizimu Melika. Izinguquko ze-Upsweep nezinkathi zonyaka, ziba zinomsindo kakhulu entwasahlobo nasekwindla, noma kungacaci ukuthi kungani. Umbono oholayo ngukuthi uhlobene nomsebenzi wentaba-mlilo.
6 | Umlozi
I-Whistle yaqoshwa ngoJulayi 7, 1997, futhi i-hydrophone eyodwa kuphela - imakrofoni zangaphansi kwamanzi ezazisetshenziswa yiNational Oceanic and Atmospheric Administration (NOAA) - eyathatha. Indawo ayaziwa futhi imininingwane elinganiselwe yenze kwaba nzima ukuqagela ngomthombo.
7 | Yehlisa kancane ijubane
ISlow Down yaqoshwa okokuqala ngoMeyi 19, 1997, futhi ibizwa nangokuthi yiqhwa eliwela phansi, yize abanye abantu begcizelela ukuthi kungaba yisigaxa esikhulu. Umsindo, ohlala cishe imizuzu eyisikhombisa, uncipha kancane kancane ebangeni, yingakho igama elithi "yehlisa ijubane." Njengo-Upsweep, umsindo ubuzwakala ngezikhathi ezithile kusukela wabonwa ekuqaleni.
8 | Ama-Skyquakes
Ama-Skyquakes, noma ama-sonic booms angachazeki, aye ezwakala emhlabeni wonke kule minyaka engama-200 edlule noma ngaphezulu, imvamisa eduze kwamanzi. La ma-headcratchers abikiwe eGanges e-India, e-East Coast nase-Finland Lakes yase-US, ngaseNorth Sea, nase-Australia, Japan nase-Italy.
Umsindo - ochazwe njengolingisa ukuduma okukhulu noma umlilo wenkanunu - uboshelwe kuyo yonke into kusuka ema-meteor angena emkhathini kuya kuphethiloli ophuma emigodini esemhlabeni (noma igesi eqhuma ngemuva kokubanjwa ngaphansi kwamanzi ngenxa yokubola kwezinto eziphilayo ) ukuzamazama komhlaba, izindiza zamasosha, imigede engaphansi kwamanzi iyawa, ngisho nomkhiqizo ongaba khona womsebenzi kazibuthe welanga noma womhlaba.
9 | I-UVB-76
I-UVB-76, eyaziwa nangokuthi i-The Buzzer, ibilokhu iveza imisakazo yama-shortwave amashumi eminyaka. Isakaza ngo-4625 kHz nangemva kwemisindo ephindaphindayo, izwi ngezikhathi ezithile lifunda izinombolo namagama ngesiRashiya. Umthombo nenjongo akukaze kunqunywe.
10 | IColossi yaseMemnon
ENtshonalanga yoMfula iNayile eduze kwaseLuxor, eGibhithe, imifanekiso emibili emikhulu yamawele imile ngokuziqhenya. Ebizwa ngeColossios yaseMemnon, bayinkokhiso kuFaro Amenhotep III. Ngo-27 BC ukuzamazama komhlaba okukhulu kwabhidliza ingxenye yesinye sezithombe ezinkulu, kwaqhekeka ingxenye engezansi kwawa okuphezulu. Ngokushesha abantu baqala ukubona okuthile okuxakile - isithombe saqala 'ukucula'. Isazi-mlando esingumGreki kanye nesazi sokuma komhlaba uStrabo, bekuzwakala njengokushaya, kuyilapho isihambi esingumGreki kanye nesazi sokuma komhlaba uPausanias ekufanisa nentambo ye-lyre eqhekezayo.
Ososayensi namuhla bacabanga ukuthi umsindo ubangelwe ukukhuphuka kokushisa nomswakama emanxiweni etshe njengoba iLanga liphuma. Kepha abakwazi ukuhlola umbono wabo, ngoba yize izithombe zisekhona, umsindo awukho. Cishe ngo-199 CE, umbusi waseRoma uSeptimius Severus wayala ukuba kulungiswe umonakalo wokuzamazama komhlaba - futhi ukucula kwaphela.
11 | Isitimela
Isitimela yigama elinikezwe umsindo orekhodwe ngoMashi 5, 1997, kuhlu lwe-Equatorial Pacific Ocean oluzimele lwe-hydrophone. Umsindo ukhuphukela kumvamisa we-quasi-steady. Ngokusho kwe-NOAA, imvelaphi yomsindo kungenzeka ukuthi ikhiqizwa yiqhwa elikhulu kakhulu leqhwa eliseRoss Sea, eduze kwaseCape Adare.
12 | IPing
I-Ping, echazwe njenge- “acoustic anomalies” “imisindo [yayo] esabisa izilwane zasolwandle”. Kuzwakala eFury naseHecla Strait, umzila omncane wamanzi olwandle ase-Arctic osesifundeni saseQikiqtaaluk eNunavut, eCanada. Kuphenywa ngabaphathi bezempi baseCanada.
13 | Umsindo Wehlathi Grove
IForest Grove Sound bekungumsindo ongachazeki, ochazwe yi-The Oregonian njenge "scream mechanical", ezwakale eForest Grove, e-Oregon ngoFebhuwari 2016. UMnyango Wezamahlathi wanquma ukuthi imishini yabo kwakungeyona imbangela yomsindo. Umsindo wenzeke ngaseGales Creek Road.
IWashington Post ichaze lo msindo njengokuzwakala “komtshingo omkhulu udlalwa phansi”, amabhuleki ezimoto, noma impempe yesitimu. Umnyango wezomlilo weForest Grove awuthathanga lo msindo njengengozi yokuphepha. Futhi ngokweNW Natural, zazingekho izinkinga ngezintambo zikagesi eForest Grove ngaleso sikhathi. Umsindo uhlala ungachazeki kuze kube namuhla.
14 | Umsindo weHavana Syndrome
Phakathi kuka-2016 no-2017, imisindo ebanga imvelaphi engaziwa kuthiwa yezwa ngabasebenzi baseMelika naseCanada eHaana, eCuba. Yilapho igama elithi “Havana Syndrome” lisuselwa khona. I-Havana syndrome iqoqo lezimpawu nezimpawu zezokwelapha ezitholwa ngabasebenzi baseMelika naseCanada baseCuba. Kusukela ngo-Agasti 2017, imibiko yaqala ukuvela ukuthi abasebenzi baseMelika nabaseCanada abasebenzela izwe eCuba babhekane nezinkinga zezempilo ezingajwayelekile, ezingachazwanga ezisukela ngasekupheleni kuka-2016.
Uhulumeni wase-US usole iCuba ngokwenza izigameko ezingacacisiwe ezidala lezi zimpawu. Izifundo ezalandela zosomaqhinga abathintekile eCuba, ezishicilelwe ephephabhukwini i-JAMA e-2018, zathola ubufakazi bokuthi osomaqhinga bathola ukulimala kobuchopho ngandlela thile, kepha ababonanga ukuthi yini imbangela yalokhu kulimala. Kamuva kwaphakanyiswa ukuthi kube ngenxa yemisebe ye-microwave njengoba ukuhlaselwa kwe-microwave ngokumelene nenxusa laseMelika eMoscow kubhalwe ngokomlando.
Abanye abacwaningi babeke ezinye izimbangela zokulimala, kufaka phakathi i-ultrasound ngokuhlanekezelwa kwe-intermodulation okubangelwa ukungasebenzi kahle noma ukubekwa ngokungafanele kwemishini yaseCuba yokuqapha, imisindo yekhilikithi, nokuchayeka emithini yokubulala izinambuzane ye-neurotoxic.
Ekuqaleni kuka-2018, izinsolo ezifana nalezo ezibikwe ngabameli baseCuba zaqala ukwenziwa ngabameli baseMelika eChina. Isigameko sokuqala esabikwa ngusomaqhinga waseMelika eChina saba ngo-Ephreli 2018 eConsulate General yase-United States, eGuangzhou, inxusa elikhulu laseMelika eChina. Esinye isigameko sasike sabikwa phambilini yisisebenzi se-USAID eHhovisi Lenxusa laseMelika eTashkent, e-Uzbekistan, ngoSepthemba 2017; Umbiko wesisebenzi wehliswe nguMnyango Wezwe wase-US.
Ngemuva kokufunda ngemisindo engajwayelekile futhi engaqondakali, yazi mayelana Izimo Zokukhanya Ezingaqondakali Ezihlala Zingachazeki.
